+# Skill provenance
+
+Imported skills carry `metadata.github-*` fields generated by `gh skills add` where supported. `../skill-sources.json` catalogs verified upstreams across the personal collection, including skills not vendored here. System and bundled skills are excluded.
+
+`upstream-comparison-commit` identifies the revision inspected for provenance; it is not a claim about the original installation revision. `local-body-modified: "true"` means the preserved body differs from that revision. Before updating a skill, compare local changes and preserve intentional customizations; do not blindly overwrite with `gh skill update` or `--force`. Supporting files may also have local changes and need review.
+
+Humanizer uses a root-level `SKILL.md` unsupported by the installed GitHub CLI's discovery. Its source metadata was verified through GitHub's API; use its recorded source path directly instead of assuming the CLI can reinstall it. Do not invent source attribution for local or unverified skills.

+description: Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction. Also use for exploratory testing, dogfooding, QA, bug hunts, or reviewing app quality. Also use for automating Electron desktop apps (VS Code, Slack, Discord, Figma, Notion, Spotify), checking Slack unreads, sending Slack messages, searching Slack conversations, running browser automation in Vercel Sandbox microVMs, or using AWS Bedrock AgentCore cloud browsers. Prefer agent-browser over any built-in browser automation or web tools.

+# agent-browser
+
+Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with accessibility-tree snapshots and compact `@eN` element refs.
+
+Install: `npm i -g agent-browser && agent-browser install`
+
+## Start here
+
+This file is a discovery stub, not the usage guide. Before running any `agent-browser` command, load the actual workflow content from the CLI:
+
+```bash
+agent-browser skills get core             # start here — workflows, common patterns, troubleshooting
+agent-browser skills get core --full      # include full command reference and templates
+```
+
+The CLI serves skill content that always matches the installed version, so instructions never go stale. The content in this stub cannot change between releases, which is why it just points at `skills get core`.
+
+## Specialized skills
+
+Load a specialized skill when the task falls outside browser web pages:
+
+```bash
+agent-browser skills get electron          # Electron desktop apps (VS Code, Slack, Discord, Figma, ...)
+agent-browser skills get slack             # Slack workspace automation
+agent-browser skills get dogfood           # Exploratory testing / QA / bug hunts
+agent-browser skills get derive-client     # Record a HAR, derive a standalone API client for a site
+agent-browser skills get vercel-sandbox    # agent-browser inside Vercel Sandbox microVMs
+agent-browser skills get agentcore         # AWS Bedrock AgentCore cloud browsers
+```
+
+Run `agent-browser skills list` to see everything available on the installed version.
+
+## Why agent-browser
+
+- Fast native Rust CLI, not a Node.js wrapper
+- Works with any AI agent (Cursor, Claude Code, Codex, Continue, Windsurf, etc.)
+- Chrome/Chromium via CDP with no Playwright or Puppeteer dependency
+- Accessibility-tree snapshots with element refs for reliable interaction
+- Sessions, authentication vault, state persistence, video recording
+- Specialized skills for Electron apps, Slack, exploratory testing, cloud providers
+
+## Observability Dashboard
+
+The dashboard runs independently of browser sessions on port 4848 and can also be opened through a proxied or forwarded URL such as `https://dashboard.agent-browser.localhost`. Agents should stay on the dashboard origin: session tabs, status, and stream traffic are proxied internally, so session ports do not need to be exposed.

+description: Build a self-contained HTML diagram explaining a code change, its control flow, and its impact. Use for visual PR explainers, architecture walkthroughs, or requests to diagram code; optionally render a PNG for sharing.
+---
+
+# Code Diagram HTML
+
+Build one self-contained HTML page that gives a reviewer a working mental model of a code change without opening the source. Preserve the project's visual identity when one exists; otherwise use the neutral defaults below. This skill has no organization-specific branding, paths, services, or browser infrastructure requirements.
+
+Save generated explainers and images in a writable artifact directory outside the repository. Never commit generated PR evidence as a hosting workaround. Return the local path and, when sharing, upload through a supported attachment mechanism. When used by `$create-pr`, follow its attachment delivery workflow.
+
+## Ground the explanation
+
+Read the actual diff and relevant code before drawing. Resolve the PR base rather than assuming a branch name. For a stack, compare against the immediate parent. Trace the entry points and decisions needed to explain the change; verify every function name, file reference, threshold, and default. Keep unknown behavior explicit and distinguish active behavior from unused scaffolding.
+
+Open with a short lede: what changed and why it matters. Show the flow rather than a file inventory. Put source references beside the claims they support, using verified repository-relative paths and line numbers. When remote source links are available, prefer links pinned to the reviewed commit.
+
+## Choose the main diagram
+
+| Shape          | Use when                                  | Layout                                               |
+| -------------- | ----------------------------------------- | ---------------------------------------------------- |
+| Sequence       | Work moves through actors over time       | Swim lanes, with steps as rows and actors as columns |
+| Flow           | Branches later reconverge                 | Top-down graph with labeled forks and merges         |
+| Decision tree  | Branches terminate independently          | Cards or a tree with explicit outcomes               |
+| Before / after | A refactor or migration is the main story | Matching rows in adjacent panels                     |
+
+Use one main diagram per page. Supporting cards or code panels can explain decisions and transformations without introducing a second competing story. Include impacted files, validation, or observability only when they help explain the actual change; do not invent instrumentation to fill a section.
+
+For flows, label each branch and show where it rejoins or terminates. Keep nodes short, move detail into adjacent notes, and highlight the path affected by the change. Prefer two-way forks where they aid reading, but preserve the real decision structure. Stop at the boundary relevant to the explanation; include response or downstream behavior when that is part of the change.
+
+## Self-contained visual design
+
+Use semantic HTML with all CSS in a `<style>` element. No frameworks, build step, external stylesheets, font CDNs, or runtime network dependencies. Use JavaScript only when interaction materially helps; the core explanation should remain readable without it. Escape code snippets as text.
+
+Match the project's established colors and typography when available. Do not copy a logo or brand treatment from an unrelated project. System fonts are a portable default; embed a local font only when its redistribution license permits it. Inline any images or SVG needed by the page.
+
+When there is no project style, use a restrained neutral theme:
+
+- Background `#f8fafc`, white cards, text `#0f172a`, muted text `#475569`, borders `#cbd5e1`.
+- One blue accent (`#2563eb`) for the changed path. Use labeled success/error states; color alone must not carry meaning.
+- System sans-serif body and headings; system monospace for code and source labels. Body text around 16px, clear heading hierarchy, comfortable line height.
+- Consistent spacing, modest rounded cards, and high contrast. Avoid decorative logos, oversized headers, or dense chrome.
+
+Make the layout work on desktop and narrow screens. Stack comparison panels on mobile, keep reading order intact, and allow local scrolling for wide code or swim lanes instead of clipping the page. Use inline SVG when connectors would otherwise become brittle CSS positioning. Include a print stylesheet when the artifact is intended for export.
+
+## Verify and deliver
+
+Open the page with an available browser or preview tool. Inspect desktop and narrow layouts for clipped text, disconnected branches, overlapping labels, and unreadable contrast. Recheck claims against the final source. If browser verification is unavailable, say so rather than claiming the page was visually checked.
+
+When invoked by `$create-pr`, PNG rendering and embedding in the PR body are mandatory; follow its upload and rendered-body verification requirements. For standalone HTML requests, PNG export remains optional.
+
+For a PNG, use the available screenshot tool to capture the full document, preferably at 2x scale. Do not assume a fixed CDP endpoint, browser port, agent host, or repository-local rendering script. Inspect the resulting image, fix layout problems, and render again if needed.
+
+Return or open the HTML artifact. When sharing through GitHub or chat, keep a concise native-format explanation alongside it: those surfaces generally cannot render the HTML inline. Attach or link the PNG and downloadable HTML through supported artifact tools. Publish to Slack or another external channel only when the user authorized that destination, and use that channel's native formatting.
+
+Use `$show-me` for the compact inline companion. The HTML carries the detailed diagram; the inline view should still communicate the essential change by itself.

+name: create-pr
+description: Create or update a GitHub pull request whose body combines show-me visuals with embedded PNGs rendered from a self-contained code-diagram-html explainer grounded in the actual diff.
+---
+
+# Create PR
+
+Make the PR body a visual explanation of the change using both `$show-me` and `$code-diagram-html`. Load those skills before composing the description. Install both alongside this skill; if either is unavailable, identify the missing dependency rather than claiming its workflow ran.
+
+## Compose from the actual change
+
+Read the repository's PR guidance and template, resolve the correct base branch, and inspect the full PR diff and relevant source. For a stacked PR, explain only its layer relative to its immediate base. Reuse an existing PR for the branch instead of creating a duplicate.
+
+Lead with one or two sentences describing the concrete problem and resulting behavior. Make the core of the body `$show-me` output: choose a Mermaid flow or sequence, a before/after diff, pseudocode, a call tree, or a component sketch that makes the change clear. Use verified identifiers and paths, and put short explanations next to the visuals. Avoid a generic inventory of changed files.
+
+Also apply `$code-diagram-html` to create one self-contained HTML explainer of the same change in a temporary artifact directory outside the repository. Upload it through a supported attachment or artifact mechanism and link it as downloadable HTML. Never commit generated HTML, PNGs, recordings, or other PR evidence to any repository branch to host them. If no supported upload path is available, retain the local artifacts and report the delivery blocker.
+
+GitHub PR bodies do not render arbitrary HTML, CSS, local filesystem links, or embedded data-URL images. The body must remain understandable without opening the HTML. Use GitHub-rendered Mermaid or fenced sketches inline. Render the HTML explainer to PNG and embed the resulting images in the PR body; this is required, not an optional attachment. Never invent an upload URL or imply that a repository HTML blob link is a live preview.
+
+Include concise validation results and any material limitations. Preserve required template fields and issue links. State exactly what ran, what passed or failed, and what remains unverified; do not claim screenshots or checks that were not performed.
+
+## Render and embed the PNGs
+
+Use `$code-diagram-html` to render the complete explainer, preferably at 2x scale. Inspect the PNG for clipped text, disconnected branches, and unreadable labels. Fix and re-render any problems. Split a tall render into readable sections when necessary, preserving the full explanation and its order.
+
+Upload the PNGs through a supported attachment or artifact mechanism. Never use committed files or raw Git URLs as an image-hosting workaround. Use image URLs that GitHub can render and reviewers can access. Never expose private artifacts through a public host just to obtain an image URL. Local paths and data URLs are not valid delivery substitutes; `gh pr create` and `gh pr edit` do not upload files referenced in Markdown.
+
+Add a `## Visualization` section to the PR body containing Markdown image embeds (`![Descriptive alt text](verified-image-url)`) for every rendered section, followed by the downloadable HTML link. A PNG link alone, an image in a comment, the HTML attachment, or a Mermaid block does not satisfy the embedded-PNG requirement.
+
+If rendering or image hosting is unavailable, preserve the completed draft and report the specific blocker. Do not silently downgrade to an HTML-only or Mermaid-only body, or claim this workflow is complete without the PNGs.
+
+## Publish and verify
+
+Follow the user's authorization and the repository's commit, push, and verification rules. A request to create a PR authorizes creating it; a request only to draft a body does not authorize publication. Use `$gh-stack` when the branch is in a stack, then edit that layer's generated PR body.
+
+Write the complete body to a temporary UTF-8 file and use `gh pr create --body-file <file>` or `gh pr edit <number> --body-file <file>`, with explicit repository and base/head scope as appropriate. Do not interpolate the body into shell code.
+
+Read back the published body and check artifact links. Open the PR in a browser and confirm the PNGs actually render in the body and remain legible at GitHub’s displayed width. A successful body update or image URL fetch alone does not prove rendering. If browser verification is unavailable, report the rendering check as unverified. Verify that diagram labels still match the final diff, after the final code changes. Return the PR URL and report any remaining delivery or validation limitations.

+
+# gh-stack
+
+`gh stack` is a [GitHub CLI](https://cli.github.com/) extension for stacked branches and pull
+requests. A stack is an ordered chain of branches rooted on a trunk, where each branch has one PR
+based on the branch below it, so a reviewer sees only that layer's diff.
+
+`gh stack` prints a stack trunk-first, left to right:
+
+```
+(main) <- auth <- api <- frontend
+```
+
+Left is the **bottom**, right is the **top**. `auth` is based on `main` and merges first;
+`frontend` merges last. `up` moves toward the top, away from trunk; `down` moves toward it.
+Foundational work belongs at the bottom, code that depends on it above. For how to choose the
+layers, read `references/stack-design.md`.
+
+## Setup
+
+```bash
+gh extension install github/gh-stack
+git config rerere.enabled true         # remember conflict resolutions
+git config remote.pushDefault origin   # required if the repo has more than one remote
+```
+
+## Non-interactive use
+
+`gh stack` branches on whether **stdout is a TTY**. Piped, most commands error cleanly or print
+static text; under a PTY the same commands open a prompt or a full-screen TUI and block forever.
+Agent harnesses differ, so always pass the flags below instead of relying on that detection.
+
+**Multiple remotes:** never run `push`, `submit`, `sync`, `rebase`, or `link` without
+`--remote <name>` unless `remote.pushDefault` is configured. `checkout` and `trunk` have no
+`--remote` flag and require the config.
+
+| Always run                                | Never run bare      | Why                                           |
+| ----------------------------------------- | ------------------- | --------------------------------------------- |
+| `gh stack view --json`                    | `gh stack view`     | opens a TUI under a PTY                       |
+| `gh stack submit --auto`                  | `gh stack submit`   | prompts for a title per new PR                |
+| `gh stack merge <target> --yes`           | `gh pr merge`       | `gh pr merge` cannot merge a stack            |
+| `gh stack init <branch>...`               | `gh stack init`     | prompts for branch names                      |
+| `gh stack add <branch>`                   | `gh stack add`      | prompts for a name, and fails even when piped |
+| `gh stack checkout <target>`              | `gh stack checkout` | opens a selection menu                        |
+| `gh stack up` / `down` / `top` / `bottom` | `gh stack switch`   | `switch` is menu-only                         |
+| —                                         | `gh stack modify`   | TUI-only, no non-interactive path             |
+
+- `view --short` is safe in both modes, but it is formatted for humans. Use `--json` to parse.
+- **`checkout <pr>` when a different local stack already covers those branches** cannot be forced.
+  Run `gh stack unstack --local` first (this keeps the stack on GitHub), then retry.
+
+## Branch placement
+
+- **Starting multi-part work:** create the stack before writing files. Do not implement every
+  concern on trunk and split it later. Put one dependent concern in each layer, bottom to top.
+- **Editing an existing stack:** check out the layer that owns the change before editing. Never
+  commit a lower layer's concern on the current top branch. Run `gh stack view --json`; if
+  ownership is unclear, inspect `git log --all -- <path>`. Then check out the owner, edit, commit,
+  rebase upstack, and return to top.
+
+```bash
+gh stack down                   # or: gh stack checkout api
+git add ... && git commit -m "Add get-user endpoint"
+gh stack rebase --upstack       # replay every branch above onto the change
+gh stack top                    # return to where you were
+gh stack push
+```
+
+## Core loop
+
+```bash
+gh stack init auth              # create the stack and check out its branch
+git add ... && git commit -m "Add auth middleware"
+gh stack add api                # next layer, branched from the current one
+git add ... && git commit -m "Add API routes"
+gh stack submit --auto          # push every branch and open draft PRs
+gh stack view --json            # confirm
+```
+
+Add `--open` to `submit` to create PRs ready for review instead of drafts. Branch names are
+verbatim — `gh stack add refactor/foo` creates `refactor/foo`.
+
+## Staying in sync
+
+```bash
+gh stack sync                   # fetch, reconcile with GitHub, rebase, push, refresh PR state
+gh stack sync --prune           # also delete local branches for merged PRs
+```
+
+Pruning never happens without `--prune` when non-interactive. If the local and remote stacks have
+diverged, `sync` prints both chains, makes no changes, and exits 0 with `Sync aborted` — see
+`references/troubleshooting.md`.
+
+## Merging
+
+Scope the merge with an argument:
+
+```bash
+gh stack merge 42 --yes          # PR #42 plus every unmerged PR below it
+gh stack merge 7 --yes           # every unmerged PR in stack #7
+gh stack merge 42 --yes --squash # or --merge, --rebase, --merge-method <method>
+```
+
+Pass a PR number to merge that PR and every unmerged PR below it, or a stack number to merge every
+unmerged PR in that stack. The operation is all-or-nothing: if any PR in that set cannot merge,
+none do.
+
+Without a method flag the last-used method is reused. If the base branch uses a merge queue, the
+stack is queued instead and the queue picks the method, ignoring any flag you passed with a
+warning; queued PRs may land in separate groups.
+
+## Reading state
+
+`gh stack view --json` writes JSON to **stdout**. Status messages go to **stderr** — do not parse
+them, branch on exit codes instead.
+
+```
+trunk           string
+currentBranch   string
+branches[]      name, head, base, isCurrent, isMerged, isQueued, needsRebase
+branches[].pr   number, url, state ("OPEN" | "MERGED" | "QUEUED"); absent when no PR exists
+```
+
+`base` is the saved SHA of the parent branch that this branch was last known to contain. It may be
+older than the parent's current tip. `needsRebase` is true when the current parent tip is no longer
+an ancestor of the branch.
+
+## Exit codes
+
+| Code | Meaning                    | Recovery                                                   |
+| ---- | -------------------------- | ---------------------------------------------------------- |
+| 0    | Success                    | —                                                          |
+| 1    | Generic error              | Read stderr                                                |
+| 2    | Not in a stack             | `gh stack init`, or `gh stack checkout <target>`           |
+| 3    | Rebase conflict            | Follow the Exit 3 recovery below                           |
+| 4    | GitHub API failure         | Check `gh auth status`, retry                              |
+| 5    | Invalid arguments          | Fix the invocation; see `<command> --help`                 |
+| 6    | Disambiguation required    | Branch is in several stacks; check out a non-shared branch |
+| 7    | Rebase already in progress | `gh stack rebase --continue` or `--abort`                  |
+| 8    | Stack file locked          | Another `gh stack` process is writing; retry after ~5s     |
+| 9    | Stacked PRs unavailable    | Not enabled on the repository; tell the user               |
+| 10   | Modify recovery required   | `gh stack modify --abort`                                  |
+
+**Exit 3 recovery:**
+
+- After `gh stack rebase`: resolve the files, run `git add`, then
+  `gh stack rebase --continue`; use `gh stack rebase --abort` to restore the stack.
+- After `gh stack sync`: the stack has already been restored. Run `gh stack rebase` to recreate the
+  conflict, then resolve and continue as above.
+
+## Constraints
+
+- Stacks are strictly linear: one parent, at most one child. Use separate stacks for parallel work.
+- There is no non-interactive reorder or removal. Errors may suggest `gh stack modify`, but it is
+  TUI-only — restructure with `unstack` then `init` instead.
+- PR titles and bodies are auto-generated. Use `gh pr edit` afterwards to change them.
+
+## More detail
+
+`gh stack <command> --help` is authoritative for flags and arguments. Note that
+`gh stack help <command>` does **not** work — it prints the top-level help.
+
+Open the reference whose trigger matches the task; no need to preload all three.
+
+- `references/stack-design.md` — read before creating a stack, when deciding how many layers to
+  use, what belongs in each one, or whether work belongs in a new stack.
+- `references/commands.md` — read when a command fails unexpectedly or you need its preconditions,
+  side effects, atomicity, or ordering guarantees.
+- `references/troubleshooting.md` — read on a rebase conflict, after a squash-merge, on local and
+  remote divergence, when restructuring a stack, or when driving stacks from another tool.

+# Command behavior
+
+`gh stack <command> --help` is authoritative for flags and arguments. (`gh stack help <command>` only prints the top-level help.) This file only covers behavior `--help` does not
+explain: preconditions, side effects, atomicity, and failure modes.

+
+## init
+
+Creates the stack and checks out the **last** branch in the list, so a single `init` can lay down
+the whole chain: `gh stack init auth api frontend`.
+
+`init` processes branch arguments from bottom to top. Existing branches are adopted. If the first
+branch does not exist, it is created from the trunk; each later new branch is created from the
+branch immediately before it. There is no separate adopt mode — existence decides. `--base`
+selects a non-default trunk.
+
+`init` also enables `git rerere`. Under a TTY the first run in a repo asks for confirmation; set
+`git config rerere.enabled true` beforehand to skip it.
+
+## add
+
+- **Must run from the top branch** of the stack (or the trunk when the stack is still empty).
+  Anywhere else it exits **5** with `can only add branches on top of the stack`. Run `gh stack top`
+  first.
+- **Uncommitted changes carry over.** Without `-Am`, `add` does not touch the working tree, so
+  staged and unstaged changes follow you onto the new branch. Commit or stash first for a clean start.
+- **`add -Am` commits in place when the current branch has no commits yet** — for example
+  immediately after `init` — instead of creating a branch. This is deliberate: the first layer
+  usually needs its content before a second layer exists.
+- `-A` and `-u` are mutually exclusive, and both require `-m`.
+
+## push
+
+Pushes every active (non-merged, non-queued) branch in one multi-ref push with per-branch
+`--force-with-lease`.
+
+**Not atomic.** Some branches may update while another is rejected. A rejection means that branch
+moved on the remote; fix that branch and rerun — rerunning is safe and skips what already landed.
+
+`push` never creates or updates pull requests. Use `submit` for that.
+
+## submit
+
+Pushes each active branch, then creates a PR for every branch that lacks one, basing it on the
+first non-merged ancestor, then links them into a Stack on GitHub.
+
+- **Not atomic.** Branches are pushed sequentially with per-branch `--force-with-lease`. If a later
+  push is rejected, earlier pushes and PR updates stand. Fix the rejection and rerun the same command.
+- **A fully merged stack cannot be extended.** When every PR in the current stack is already merged,
+  `submit` forks the remaining unmerged branches into a **new** stack rooted at the trunk and creates
+  it on GitHub, leaving the merged stack untouched.
+- **Title generation with `--auto`:** a branch with a single commit uses that commit's subject as
+  the title and its body as the PR body. A branch with multiple commits humanizes the branch name
+  (hyphens and underscores become spaces). There is no flag for a custom title or body; use
+  `gh pr edit` afterwards.
+- `--open` marks new _and existing_ PRs ready for review; without it new PRs are drafts.
+- Requires stacked PRs to be enabled on the repository. If not, `submit` exits **9** when
+  non-interactive (under a TTY it offers to create ordinary unstacked PRs instead).
+
+## link
+
+Creates or updates a stack on GitHub **without any local tracking state**. This is the path for
+branches managed by another tool or living in another worktree — see `troubleshooting.md`.
+
+- Arguments are given bottom to top. Each is a branch name or a PR number; a numeric argument is
+  tried as a PR number first and falls back to a branch name.
+- **A numeric first argument is treated as a stack number only when a stack with that number
+  exists.** In that case the remaining arguments are appended to the top of that stack and you do
+  not re-list its current PRs: `gh stack link 7 feature-c`. Arguments already in the stack are
+  skipped; arguments belonging to a different stack are rejected.
+- Branch arguments are pushed automatically (non-force, atomic). Missing PRs are created with
+  auto-generated titles and correctly chained bases; existing PRs with a wrong base are corrected.
+- Stack membership is **additive only** — `link` never removes a PR from a stack.
+
+## sync
+
+The routine command. Steps, in order:
+
+1. **Fetch** from the remote.
+2. **Reconcile with the GitHub stack.** PRs added to the stack on github.com are pulled down and
+   appended locally. On divergence, aborts when non-interactive (see `troubleshooting.md`).
+3. **Fast-forward the trunk.** Skipped when already current; warns when diverged.
+4. **Cascade rebase when needed.** This runs if the trunk moved, a stack branch was fast-forwarded
+   from its remote, or a branch no longer contains its expected parent. Merged PRs are handled
+   automatically. On conflict, **all branches are restored** to their pre-rebase state and the
+   command exits **3**.
+5. **Push** all active branches, atomically.
+6. **Refresh PR state** from GitHub.
+7. **Sync the stack object** — link open PRs into a stack, additively. Only when two or more PRs
+   exist. `sync` never opens PRs; that is `submit`.
+8. **Prune** local branches for merged PRs, only when `--prune` is passed in a non-interactive
+   environment.
+
+## rebase
+
+Pulls from the remote and cascade-rebases. Use it when `sync` reported a conflict or when you need
+to rebase only part of the stack.
+
+- `--upstack` rebases from the current branch to the top. This is what you run after editing a
+  lower layer.
+- `--downstack` rebases from the trunk to the current branch.
+- `--no-trunk` skips fetching and the trunk rebase entirely, aligning stack branches with each
+  other only.
+- `--continue` after staging resolutions; `--abort` restores every branch.
+- A merged PR is detected automatically and replayed with `--onto` against the correct target, so a
+  squash-merged parent does not produce spurious conflicts.
+- Starting a rebase while one is in progress exits **7**.
+
+## view
+
+- `--json` writes the machine-readable payload to stdout. Its schema is in `SKILL.md`.
+- Bare `view` opens a full-screen TUI when stdout is a TTY, and prints static text when piped.
+- `--short` prints a compact one-line-per-branch summary and never opens the TUI, but it is
+  formatted for humans; parse `--json` instead.
+- `view` refreshes PR state from GitHub as a side effect, best-effort — it does not fail when the
+  API is unreachable.
+
+## checkout
+
+Accepts a stack number, PR number, PR URL, or branch name.
+
+- A bare number resolves as a **stack number first**, then a PR number, then a branch name.
+- Stack numbers, PR numbers, and PR URLs fetch from GitHub, pull the branches down, and set the
+  stack up locally.
+- If a local stack already exists over those branches with a different composition, `checkout`
+  cannot be forced past it. Run `gh stack unstack --local` first, then retry.
+- `checkout` has no flags. It relies on `remote.pushDefault` when several remotes exist.
+
+## unstack
+
+Removes the stack **grouping** only. It never deletes pull requests or branches.
+
+- With no argument it targets the active stack — the one containing the current branch — removing
+  it on GitHub and locally.
+- With a stack number it works from anywhere in the repository, tracked locally or not, via the API.
+  Local tracking is also removed when present.
+- `--local` removes local tracking only and never contacts GitHub. Combining `--local` with a stack
+  number that is not tracked locally is an error.
+- An unknown stack number exits **2**.
+
+## merge
+
+- Scope with an argument: pass a PR number to merge that PR and every unmerged PR below it in the
+  stack, or pass a stack number to merge every unmerged PR in that stack.
+- **All-or-nothing.** If any PR in that exact merge set cannot be merged, none are, and the reason
+  is reported.
+- The method comes from `--squash`, `--rebase`, `--merge`, or `--merge-method <method>`. Without
+  one, the last-used method is reused.
+- Only basic PR state is checked before merging: open and not a draft. Bypassing merge requirements
+  is not supported for stacks.
+- **A merge queue on the base branch overrides everything.** The stack is added to the queue rather
+  than merged; the queue chooses the method and any method flag you passed is ignored with a
+  warning. Queued PRs are submitted together but land as the queue processes them, so they may merge
+  in separate groups rather than all at once.
+- `gh pr merge` cannot merge a stack. Always use `gh stack merge`.
+
+## Navigation
+
+`up`, `down`, `top`, `bottom`, and `trunk` are always non-interactive. `up` and `down` accept a
+count (`gh stack up 3`). Movement clamps at the stack bounds, and merged branches are skipped when
+navigating from an active branch, so `bottom` lands on the lowest _unmerged_ branch.
+
+`gh stack switch` is a selection menu with no non-interactive path. Use the commands above instead.

+# Designing a stack
+
+How to decide what goes in each layer. Read this before running `gh stack init`.
+
+## Contents
+
+- [Plan the layers before writing code](#plan-the-layers-before-writing-code)
+- [Branch naming](#branch-naming)
+- [Staging changes deliberately](#staging-changes-deliberately)
+- [When to add a layer](#when-to-add-a-layer)
+- [One stack, one story](#one-stack-one-story)
+
+## Plan the layers before writing code
+
+A stack is a dependency chain. If code in one layer depends on code in another, the dependency must
+live in the same branch or a lower one. That constraint is much cheaper to satisfy by planning than
+by restructuring later, because there is no non-interactive in-place reorder — fixing the order
+means`unstack` and `init` again.
+
+Decide the layers first, then write code into them:
+
+```
+(main) <- todo-app/models <- todo-app/api <- todo-app/frontend <- todo-app/integration
+```
+
+- `todo-app/models` — shared types and schema
+- `todo-app/api` — routes that use the models
+- `todo-app/frontend` — components that call the routes
+- `todo-app/integration` — tests exercising the whole feature
+
+This is illustrative. Infer the stack topic and layer names from the actual task; do not reuse
+`todo-app` or these layer names literally.
+
+The failure mode to avoid is writing everything on one branch and trying to split it afterwards.
+If a task is large enough to warrant a stack, create the stack at the start.
+
+## Branch naming
+
+Prefer a shared topic prefix plus the layer's concern:
+`<topic>/<concern>` — for example, `billing/schema`, `billing/api`, `billing/ui`.
+This keeps related branches recognizable without using generic names that could belong to any
+stack. **User and repository branch naming conventions take precedence; follow them instead.**
+
+Names are used exactly as given — nothing is prepended or transformed, and slashes are kept, so
+`gh stack add refactor/foo` creates a branch literally named `refactor/foo`.
+
+If you pass `-m` without a branch name, the name is generated from the commit message in
+date-and-slug form (for example `03-24-add_api_routes`). Prefer naming the branch yourself.
+
+## Staging changes deliberately
+
+Use `git add` and `git commit` directly rather than the `add -Am` shortcut. The point is control
+over which changes land in which branch. With several modified files in the working tree, stage the
+subset that belongs to the current layer, commit it, then create the next branch and stage the rest
+there:
+
+```bash
+git add internal/models/user.go internal/models/session.go
+git commit -m "Add user and session models"
+
+gh stack add api-routes
+git add internal/api/routes.go internal/api/handlers.go
+git commit -m "Add user API routes"
+```
+
+Multiple commits per branch are fine. What matters is that every commit in a branch serves the same
+concern, and that a change belonging to a different concern goes in a different branch.
+
+Note that `gh stack add <branch>` without `-Am` does not touch the working tree, so uncommitted
+changes carry over to the new branch. Commit or stash first if you want the new layer to start clean.
+
+## When to add a layer
+
+Add a branch when you start a **different concern that depends on what you have built so far**.
+Signals:
+
+- Moving from backend to frontend, or from core logic to tests or documentation
+- The next changes have a different reviewer audience
+- The current branch's diff is already large enough to review on its own
+
+A layer that cannot be described in one sentence is usually two layers.
+
+## One stack, one story
+
+A stack should read as a coherent progression: a reviewer walks the PRs bottom to top and sees the
+feature being built.
+
+**Use a single stack** when every branch serves the same feature or project, even if the layers span
+different concerns.
+
+**Start a separate stack** for unrelated work — a different feature, an unrelated bug fix, an
+independent refactor. Do not mix efforts into one stack just because you happened to work on both.
+Use `gh stack init` for the new effort, or `gh stack checkout <target>` to move between existing
+stacks.
+
+A trivial incidental fix can ride along in the current stack. Once it grows into its own project, it
+deserves its own stack.

+
+## Rebase conflicts (exit 3)
+
+`rebase` and `sync` both exit 3 on conflict. `sync` restores every branch to its pre-rebase state
+first, so a failed `sync` leaves nothing half-applied; a failed `rebase` stops mid-flight and waits.
+
+```bash
+gh stack rebase
+# exit 3 — conflicted paths are listed on stderr
+git add <resolved paths>
+gh stack rebase --continue     # repeat if the next branch also conflicts
+```
+
+`gh stack rebase --abort` restores every branch in the stack, not just the current one.
+
+Because `init` enables `git rerere`, a conflict you resolve once is replayed automatically the next
+time the same conflict appears — which is common, since a change low in the stack is rebased through
+every branch above it. Without `rerere`, repeated conflicts may need manual resolution on each
+affected layer.
+
+## After a squash merge
+
+A squash merge replaces the branch's commits with one new commit, so the originals no longer exist
+in the trunk's history and an ordinary rebase would try to replay them again.
+
+`gh stack sync` detects this and rebases with `--onto` against the correct target, skipping the
+merged branch:
+
+```bash
+gh stack sync
+gh stack view --json    # merged branch reports "isMerged": true, "state": "MERGED"
+```
+
+No manual action is needed. If the replay conflicts, `sync` restores all branches and exits 3.
+Run `gh stack rebase` to rerun the rebase, which will stop at the conflict and allow you to resolve
+and then `--continue` until complete. Use `gh stack sync --prune` to also delete local branches for
+merged PRs.
+
+## Local and remote stacks have diverged
+
+Divergence means the local stack and the stack on GitHub changed in different ways — for example
+branches were added locally while a PR was added to the stack on github.com.
+
+When non-interactive, `sync` prints both chains, changes nothing, and exits **0** with
+`Sync aborted`. Success here does not mean the sync happened; check for that message, or re-run
+`gh stack view --json` and compare.
+
+Two resolution paths:
+
+- **Keep the remote version.** Drop local tracking and pull the stack back down.
+
+  ```bash
+  gh stack unstack --local          # keeps the stack on GitHub
+  gh stack checkout <stack-number>  # or a PR number
+  ```
+
+- **Keep the local version.** Remove the grouping on GitHub, then recreate it from local state.
+
+  ```bash
+  gh stack unstack                  # removes the grouping; PRs and branches survive
+  gh stack submit --auto
+  ```
+
+Neither path deletes pull requests or branches.
+Remote unstacking leaves PRs that are merging (auto-merge enabled) or are queued (in a merge queue)
+stacked. If needed, clear that state before retrying.
+
+## Restructuring a stack
+
+There is no non-interactive reorder, rename, or removal. `add` run from the wrong branch suggests
+`gh stack modify`, but that is TUI-only. Tear the stack down and rebuild it instead:
+
+```bash
+gh stack unstack                       # removes local tracking and the GitHub grouping
+# Rename or drop branches, and rewrite ancestry as needed.
+gh stack init --base main branch-1 branch-2 branch-3
+gh stack submit --auto                 # re-link on GitHub
+```
+
+`init` adopts branches that already exist, so the rebuild reuses them rather than creating new ones.
+Existing PRs survive. Once Git ancestry is correct, `submit` updates their base branches and
+re-links the stack on GitHub.
+
+Changing metadata does **not** change Git ancestry. Reorder commits first, then rebuild the stack.
+For example, to change `main <- models <- migration <- ui` into
+`main <- migration <- models <- ui`:
+
+```bash
+old_models=$(git rev-parse models)
+old_migration=$(git rev-parse migration)
+git rebase --onto main "$old_models" migration
+git rebase --onto migration main models
+git rebase --onto models "$old_migration" ui
+gh stack unstack
+gh stack init --base main migration models ui
+```
+
+The first rebase moves migration-only commits onto trunk, the second replays model commits above
+them, and the third replays UI-only commits above models. Preserve the old boundary SHAs before
+moving any branch. For a different reorder, identify each layer's range with
+`git log <old-parent>..<branch>`, then replay the ranges bottom to top.
+
+## Branch belongs to several stacks (exit 6)
+
+Commands exit 6 when the current branch cannot identify a single stack — typically because it is the
+trunk of more than one stack. There is no flag to disambiguate.
+
+```bash
+gh stack checkout <a-branch-unique-to-the-intended-stack>
+```
+
+Then rerun. Commands that take an explicit stack number (`merge 7`, `unstack 7`) sidestep the
+problem entirely, since they do not infer the stack from the current branch.
+
+## Driving stacks from another tool or worktree
+
+`gh stack link` creates and updates stacks purely through the API, with no local tracking state.
+Use it when branches are managed by jj, Sapling, git-town, a separate worktree, or any workflow
+where the local `.git/gh-stack` file would be wrong or absent.
+
+```bash
+gh stack link branch-a branch-b branch-c        # bottom to top
+gh stack link --base develop --open a b c       # non-default trunk, ready for review
+gh stack link 10 20 30                          # by PR number
+gh stack link 7 feature-d                       # append to existing stack #7
+```
+
+Because `link` writes no local state, the local navigation commands (`up`, `down`, `top`, `bottom`)
+will not work on the result. Use `gh stack checkout <stack-number>` if you later want local tracking.
+
+## Stack file is locked (exit 8)
+
+Another `gh stack` process holds the exclusive lock on `.git/gh-stack.lock`. The lock times out
+after about five seconds, so wait and retry. A persistent exit 8 means another process still holds
+the lock; identify and stop that process before retrying.
+
+## An interrupted modify session (exit 10)
+
+`gh stack modify` is TUI-only and should never be invoked by an agent. If a repository is left in
+this state by someone else, restore it:
+
+```bash
+gh stack modify --abort
+```
+
+Related: `submit` also detects a pending modify state, and under a TTY asks before overwriting the
+stack on GitHub with local state.

+# Git Commit with Conventional Commits
+
+## Overview
+
+Create standardized, semantic git commits using the Conventional Commits specification. Analyze the actual diff to determine appropriate type, scope, and message.
+
+## Conventional Commit Format
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+## Commit Types
+
+| Type       | Purpose                        |
+| ---------- | ------------------------------ |
+| `feat`     | New feature                    |
+| `fix`      | Bug fix                        |
+| `docs`     | Documentation only             |
+| `style`    | Formatting/style (no logic)    |
+| `refactor` | Code refactor (no feature/fix) |
+| `perf`     | Performance improvement        |
+| `test`     | Add/update tests               |
+| `build`    | Build system/dependencies      |
+| `ci`       | CI/config changes              |
+| `chore`    | Maintenance/misc               |
+| `revert`   | Revert commit                  |
+
+## Breaking Changes
+
+```
+# Exclamation mark after type/scope
+feat!: remove deprecated endpoint
+
+# BREAKING CHANGE footer
+feat: allow config to extend other configs
+
+BREAKING CHANGE: `extends` key behavior changed
+```
+
+## Workflow
+
+### 1. Analyze Diff
+
+```bash
+# If files are staged, use staged diff
+git diff --staged
+
+# If nothing staged, use working tree diff
+git diff
+
+# Also check status
+git status --porcelain
+```
+
+### 2. Stage Files (if needed)
+
+If nothing is staged or you want to group changes differently:
+
+```bash
+# Stage specific files
+git add path/to/file1 path/to/file2
+
+# Stage by pattern
+git add *.test.*
+git add src/components/*
+
+# Interactive staging
+git add -p
+```
+
+**Never commit secrets** (.env, credentials.json, private keys).
+
+### 3. Generate Commit Message
+
+Analyze the diff to determine:
+
+- **Type**: What kind of change is this?
+- **Scope**: What area/module is affected?
+- **Description**: One-line summary of what changed (present tense, imperative mood, <72 chars)
+
+### 4. Execute Commit
+
+```bash
+# Single line
+git commit -m "<type>[scope]: <description>"
+
+# Multi-line with body/footer
+git commit -m "$(cat <<'EOF'
+<type>[scope]: <description>
+
+<optional body>
+
+<optional footer>
+EOF
+)"
+```
+
+## Best Practices
+
+- One logical change per commit
+- Present tense: "add" not "added"
+- Imperative mood: "fix bug" not "fixes bug"
+- Reference issues: `Closes #123`, `Refs #456`
+- Keep description under 72 characters
+

+
+# Humanizer: remove AI writing patterns
+
+Rewrite AI-sounding text so it reads like the writer, not a chatbot. Do not change what it says or make up details.
+
+The patterns below come from Wikipedia's ["Signs of AI writing"](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing), maintained by WikiProject AI Cleanup.
+
+## What to do
+
+When given text to humanize:
+
+1. **Find AI patterns.** Check the text against the patterns below.
+2. **Keep every claim.** You may shorten dull parts, expand useful parts, and merge or split paragraphs. Keep the information even when you change the structure.
+3. **Do not invent facts.** Do not add a fact, name, number, date, quote, or citation unless it comes from the source or the user. If a sentence needs a missing detail, ask for it or use a simpler sentence. You may add an opinion or reaction when the writer's voice calls for one, but you may not add a factual claim. Fiction is exempt because invented details are part of the task.
+4. **Match the voice.** Use the right tone for the text, such as formal, casual, or technical. Add personality only when the text and the writer call for it.
+
+The input type controls what you return. See [How to return the result](#how-to-return-the-result). Use the same rewrite process in every mode.
+
+## Match the writer's voice
+
+If the user provides a writing sample (their own previous writing), analyze it before rewriting:
+
+1. Read the sample first. Note its sentence length, word choice, paragraph openings, punctuation, repeated phrases, and transitions.
+2. Match those habits. Do not replace casual words with formal ones or remove deliberate quirks.
+3. If there is no sample, use the guidance below.
+
+A writing sample takes priority over these style rules. If the sample uses em dashes, keep them at about the same rate. Do not apply §14 as a ban.
+
+## Add personality only when it fits
+
+Removing AI patterns is only half the job. The result should still sound like a person.
+
+Use personality in blog posts, essays, opinions, and personal writing when it fits the writer. Keep reference, technical, legal, and factual text neutral. Do not add opinions or first-person language where they do not belong.
+
+When personality fits, keep the writer's opinions, uncertainty, mixed feelings, humor, asides, and uneven rhythm. Never invent facts to make the text feel personal.
+
+## Content patterns
+
+### 1. Inflated claims about importance and legacy
+
+**Words to watch:** stands/serves as, is a testament/reminder, a vital/significant/crucial/pivotal/key role/moment, underscores/highlights its importance/significance, reflects broader, symbolizing its ongoing/enduring/lasting, contributing to the, setting the stage for, marking/shaping the, represents/marks a shift, key turning point, evolving landscape, focal point, indelible mark, deeply rooted
+**Problem:** AI writing often claims that ordinary details mark a major change, prove a legacy, or reflect a broad trend.
+**Before:**
+
+> The Statistical Institute of Catalonia was officially established in 1989, marking a pivotal moment in the evolution of regional statistics in Spain. This initiative was part of a broader movement across Spain to decentralize administrative functions and enhance regional governance.
+> **After:**
+> The Statistical Institute of Catalonia was established in 1989, part of a wider decentralization of administrative functions in Spain.
+
+### 2. Name-dropping to prove importance
+
+**Words to watch:** independent coverage, local/regional/national media outlets, written by a leading expert, active social media presence
+**Problem:** AI writing often lists well-known publications or follower counts to prove that a person matters. The list usually gives no useful context.
+**Before:**
+
+> Her views have been cited in The New York Times, BBC, Financial Times, and The Hindu. She maintains an active social media presence with over 500,000 followers.
+> **After:**
+> Her views have been cited in The New York Times and the BBC.
+
+If the source explains what the person said and where, keep that useful citation. Do not invent context for a shorter version.
+
+### 3. Shallow analysis with -ing phrases
+
+**Words to watch:** highlighting/underscoring/emphasizing..., ensuring..., reflecting/symbolizing..., contributing to..., cultivating/fostering..., encompassing..., showcasing...
+**Problem:** AI writing often adds an -ing phrase to make a simple fact sound deeper than it is.
+**Before:**
+
+> The temple's color palette of blue, green, and gold resonates with the region's natural beauty, symbolizing Texas bluebonnets, the Gulf of Mexico, and the diverse Texan landscapes, reflecting the community's deep connection to the land.
+> **After:**
+> The temple is painted blue, green, and gold, colors meant to evoke Texas bluebonnets and the Gulf of Mexico.
+
+### 4. Sales language
+
+**Words to watch:** boasts a, vibrant, rich (figurative), profound, enhancing its, showcasing, exemplifies, commitment to, natural beauty, nestled, in the heart of, groundbreaking (figurative), renowned, breathtaking, must-visit, stunning
+**Problem:** AI writing often sounds like an advertisement, especially when it describes places, culture, products, or organizations.
+**Before:**
+
+> Nestled within the breathtaking region of Gonder in Ethiopia, Alamata Raya Kobo stands as a vibrant town with a rich cultural heritage and stunning natural beauty.
+> **After:**
+> Alamata Raya Kobo is a town in the Gonder region of Ethiopia.
+
+### 5. Vague sources
+
+**Words to watch:** Industry reports, Observers have cited, Experts argue, Some critics argue, several sources/publications (when few cited)
+**Problem:** AI writing often assigns a claim to unnamed experts, critics, reports, or observers.
+**Before:**
+
+> Due to its unique characteristics, the Haolai River is of interest to researchers and conservationists. Experts believe it plays a crucial role in the regional ecosystem.
+> **After:**
+> Researchers and conservationists study the Haolai River for its unusual characteristics.
+
+Name a real source when the source text provides one. Otherwise, remove the unsupported claim. Never invent a source.
+
+### 6. Formulaic challenges and outlook sections
+
+**Words to watch:** Despite its... faces several challenges..., Despite these challenges, Challenges and Legacy, Future Outlook
+**Problem:** AI articles often add a stock section about challenges, future prospects, or continued growth. These sections usually repeat vague claims instead of adding facts.
+**Before:**
+
+> Despite its industrial prosperity, Korattur faces challenges typical of urban areas, including traffic congestion and water scarcity. Despite these challenges, with its strategic location and ongoing initiatives, Korattur continues to thrive as an integral part of Chennai's growth.
+> **After:**
+> Korattur has recurring traffic congestion and water shortages.
+
+Add details such as dates or public actions only when they come from the source or the user.
+
+## Language and grammar patterns
+
+### 7. Overused AI words
+
+**High-frequency AI words:** Actually, additionally, align with, crucial, delve, emphasizing, enduring, enhance, fostering, garner, gate/gated/gating (figurative; preserve established technical usage), highlight (verb), interplay, intricate/intricacies, key (adjective), landscape (abstract noun), pivotal, quietly, showcase, tapestry (abstract noun), testament, underscore (verb), valuable, vibrant
+**Problem:** AI writing uses these words much more often than most people do, especially in groups.
+**Before:**
+
+> Additionally, a distinctive feature of Somali cuisine is the incorporation of camel meat. An enduring testament to Italian colonial influence is the widespread adoption of pasta in the local culinary landscape, showcasing how these dishes have integrated into the traditional diet.
+> **After:**
+> Somali cuisine also includes camel meat, which is considered a delicacy. Pasta dishes, introduced during Italian colonization, remain common, especially in the south.
+
+### 8. Avoiding is and are
+
+**Words to watch:** serves as/stands as/marks/represents [a], boasts/features/offers [a]
+**Problem:** AI writing often replaces simple verbs such as _is_, _are_, and _has_ with longer phrases.
+**Before:**
+
+> Gallery 825 serves as LAAA's exhibition space for contemporary art. The gallery features four separate spaces and boasts over 3,000 square feet.
+> **After:**
+> Gallery 825 is LAAA's exhibition space for contemporary art. The gallery has four rooms totaling 3,000 square feet.
+
+### 9. Not X but Y and clipped negative endings
+
+**Problem:** AI writing overuses forms such as "Not only...but..." and "It's not just X, it's Y."
+
+It also adds clipped endings such as "no guessing" instead of writing a clear clause.
+**Before:**
+
+> It's not just about the beat riding under the vocals; it's part of the aggression and atmosphere. It's not merely a song, it's a statement.
+> **After:**
+> The heavy beat adds to the aggressive tone.
+> **Before (tailing negation):**
+> The options come from the selected item, no guessing.
+> **After:**
+> The options come from the selected item without forcing the user to guess.
+
+### 10. Forced groups of three
+
+**Problem:** AI writing often forces ideas into groups of three to sound complete.
+**Before:**
+
+> The event features keynote sessions, panel discussions, and networking opportunities. Attendees can expect innovation, inspiration, and industry insights.
+> **After:**
+> The event includes talks and panels. There's also time for informal networking between sessions.
+
+### 11. Changing names and repeating sentence openings
+
+**Problem:** AI writing handles repetition by rule instead of by ear. It may keep renaming the same person or thing. It may also start several sentences with the same subject, often _she_ or _he_.
+
+Use one clear name for the same subject. For repeated openings, merge sentences, change the subject when that helps, or begin with the action.
+**Before (synonym cycling):**
+
+> The protagonist faces many challenges. The main character must overcome obstacles. The central figure eventually triumphs. The hero returns home.
+> **After:**
+> The protagonist faces many challenges but eventually triumphs and returns home.
+> **Before (repeated openings):**
+> She noted the door. She noted the lock on it. She filed both away.
+> **After:**
+> She noted the door and its lock, then filed both away.
+
+Do not ban the repeated word. Fix the repeated sentence pattern. The remaining sentence may still start with "She."
+
+### 12. False from X to Y ranges
+
+**Problem:** AI writing often uses "from X to Y" when X and Y do not form a real range.
+**Before:**
+
+> Our journey through the universe has taken us from the singularity of the Big Bang to the grand cosmic web, from the birth and death of stars to the enigmatic dance of dark matter.
+> **After:**
+> The book covers the Big Bang, star formation, and current theories about dark matter.
+
+### 13. Passive voice and missing subjects
+
+**Problem:** AI writing often hides who acts or drops the subject. Use active voice when it makes the actor and action clearer.
+**Before:**
+
+> No configuration file needed. The results are preserved automatically.
+> **After:**
+> You do not need a configuration file. The system preserves the results automatically.
+
+## Style patterns
+
+### 14. Em and en dashes
+
+**Rule:** The final rewrite must not contain em dashes (—) or en dashes (–), unless the writer's sample uses them. Replace a dash with a period, comma, colon, or parentheses, or rewrite the sentence. Also check for spaced dashes (`—`) and double hyphens (`--`) used as dashes.
+**Before:**
+
+> The term is primarily promoted by Dutch institutions—not by the people themselves. You don't say "Netherlands, Europe" as an address—yet this mislabeling continues—even in official documents.
+> **After:**
+> The term is primarily promoted by Dutch institutions, not by the people themselves. You don't say "Netherlands, Europe" as an address, yet this mislabeling continues in official documents.
+> **Before:**
+> The new policy — announced without warning — affects thousands of workers. The changes -- long overdue according to critics -- will take effect immediately.
+> **After:**
+> The new policy, announced without warning, affects thousands of workers. The changes, long overdue according to critics, will take effect immediately.
+
+Before returning the rewrite, search for `—` and `–`. Remove each one unless the writer's sample uses that mark. In that case, match the sample's rate.
+
+### 15. Too much bold text
+
+**Problem:** AI chatbots often bold words and phrases without a clear reason.
+**Before:**
+
+> It blends **OKRs (Objectives and Key Results)**, **KPIs (Key Performance Indicators)**, and visual strategy tools such as the **Business Model Canvas (BMC)** and **Balanced Scorecard (BSC)**.
+> **After:**
+> It blends OKRs, KPIs, and visual strategy tools like the Business Model Canvas and Balanced Scorecard.
+
+### 16. Lists with bold mini-headings
+
+**Problem:** AI writing often uses vertical lists in which every item starts with a bold label and a colon.
+**Before:**
+
+> - **User Experience:** The user experience has been significantly improved with a new interface.
+> - **Performance:** Performance has been enhanced through optimized algorithms.
+> - **Security:** Security has been strengthened with end-to-end encryption.
+>   **After:**
+>   The update improves the interface, speeds up load times through optimized algorithms, and adds end-to-end encryption.
+
+### 17. Title case in headings
+
+**Problem:** AI chatbots often capitalize every main word in a heading.
+**Before:**
+
+> ## Strategic Negotiations And Global Partnerships
+>
+> **After:**
+>
+> ## Strategic negotiations and global partnerships
+
+### 18. Emojis
+
+**Problem:** AI chatbots often add emojis to headings and list items as decoration.
+**Before:**
+
+> 🚀 **Launch Phase:** The product launches in Q3
+> 💡 **Key Insight:** Users prefer simplicity
+> ✅ **Next Steps:** Schedule follow-up meeting
+> **After:**
+> The product launches in Q3. User research showed a preference for simplicity. Next step: schedule a follow-up meeting.
+
+### 19. Curly quotation marks
+
+**Problem:** ChatGPT often uses curly quotes (“...”) where the writer or target format uses straight quotes ("...").
+**Before:**
+
+> He said “the project is on track” but others disagreed.
+> **After:**
+> He said "the project is on track" but others disagreed.
+
+## Chatbot patterns
+
+### 20. Chatbot text left in the answer
+
+**Words to watch:** I hope this helps, Of course!, Certainly!, You're absolutely right!, Would you like..., Want me to...?, Want me to give examples?, Should I continue?, let me know, here is a...
+**Problem:** A chatbot's greeting, offer, or closing sometimes remains in text that should stand on its own.
+**Before:**
+
+> Here is an overview of the French Revolution. I hope this helps! Let me know if you'd like me to expand on any section.
+> **After:**
+> The French Revolution began in 1789 when financial crisis and food shortages led to widespread unrest.
+
+### 21. Knowledge-limit disclaimers and guesses
+
+**Words to watch:** as of [date], Up to my last training update, While specific details are limited/scarce..., based on available information, not publicly available, maintains a low profile, keeps personal details private, prefers to stay out of the spotlight, likely [grew up/studied/began], it is believed that
+**Problem:** Older models may mention the date when their knowledge ends. A model may also explain that it could not find a source, then fill the gap with a plausible guess. State what the source does not show, or remove the sentence. Do not present a guess as a fact.
+**Before (cutoff disclaimer):**
+
+> While specific details about the company's founding are not extensively documented in readily available sources, it appears to have been established sometime in the 1990s.
+> **After:**
+> The company's founding date is not documented in the available sources. (Or cut the sentence. State a date only if a source provides one.)
+> **Before (speculative gap-fill):**
+> Information about her early life is not publicly available, suggesting she maintains a low profile and keeps personal details private. She likely grew up in a middle-class household, which shaped her later interest in education reform.
+> **After:**
+> Her early life is not documented in the available sources. (Or omit the section.)
+
+### 22. Overly agreeable tone
+
+**Problem:** AI assistants often praise the user or agree before giving the answer.
+**Before:**
+
+> Great question! You're absolutely right that this is a complex topic. That's an excellent point about the economic factors.
+> **After:**
+> The economic factors you mentioned are relevant here.
+
+## Filler and hedging
+
+### 23. Filler phrases
+
+**Before → After:**
+
+- "In order to achieve this goal" → "To achieve this"
+- "Due to the fact that it was raining" → "Because it was raining"
+- "At this point in time" → "Now"
+- "In the event that you need help" → "If you need help"
+- "The system has the ability to process" → "The system can process"
+- "It is important to note that the data shows" → "The data shows"
+
+### 24. Too many qualifiers
+
+**Phrases to watch:** to be fair, it's also possible, could potentially, might arguably, in some cases it may, this is an inference
+**Problem:** Repeated editing can add one qualifier after another until every claim sounds uncertain. Keep a qualifier only when the source supports it and the meaning needs it. Remove caveats that only repair an earlier overstatement.
+**Before:**
+
+> It could potentially possibly be argued that the policy might have some effect on outcomes.
+> **After:**
+> The policy may affect outcomes.
+
+### 25. Generic positive endings
+
+**Problem:** AI writing often ends with vague optimism instead of the last useful fact.
+**Before:**
+
+> The future looks bright for the company. Exciting times lie ahead as they continue their journey toward excellence. This represents a major step in the right direction.
+> **After:**
+> (Cut the paragraph. End on the last concrete fact instead of a send-off. If the source states real plans, use those.)
+
+### 26. Too many hyphenated word pairs
+
+**Words to watch:** third-party, cross-functional, client-facing, data-driven, decision-making, well-known, high-quality, real-time, long-term, end-to-end
+**Problem:** AI writing often hyphenates these pairs everywhere. Keep the hyphen before a noun when grammar needs it, as in `a high-quality report`. Drop it after the noun, as in `the report is high quality`.
+**Before:**
+
+> The cross-functional team delivered a high-quality, data-driven report. The team is cross-functional, the report is high-quality, and the methodology is data-driven.
+> **After:**
+> The cross-functional team delivered a high-quality, data-driven report. The team is cross functional, the report is high quality, and the methodology is data driven.
+
+### 27. Pretending to reveal a deeper truth
+
+**Phrases to watch:** The real question is, at its core, in reality, what really matters, fundamentally, the deeper issue, the heart of the matter
+**Problem:** AI writing uses these phrases to make an ordinary point sound like a hidden truth.
+**Before:**
+
+> The real question is whether teams can adapt. At its core, what really matters is organizational readiness.
+> **After:**
+> The question is whether teams can adapt. That mostly depends on whether the organization is ready to change its habits.
+
+### 28. Announcing the next point
+
+**Phrases to watch:** Let's dive in, let's explore, let's break this down, here's what you need to know, now let's look at, without further ado, heads up, quick note, before I forget
+**Problem:** AI writing often announces the next point instead of stating it. A casual phrase such as "one thing that bit me" can have the same problem. Remove the announcement, not just its formal tone.
+**Before:**
+
+> Let's dive into how caching works in Next.js. Here's what you need to know.
+> **After:**
+> Next.js caches data at multiple layers, including request memoization, the data cache, and the router cache.
+> **Before (casual register):**
+> One thing that bit me hard, so pay attention to this part: the webpack dev server doesn't send the CORS header by default.
+> **After:**
+> The webpack dev server doesn't send the CORS header by default.
+
+### 29. A heading repeated in the first sentence
+
+**Signs to watch:** A heading followed by a one-line paragraph that simply restates the heading before the real content begins.
+**Problem:** AI writing often follows a heading with a sentence that only repeats the heading. Remove the repeated sentence.
+**Before:**
+
+> ## Performance
+>
+> Speed matters.
+>
+> When users hit a slow page, they leave.
+> **After:**
+>
+> ## Performance
+>
+> When users hit a slow page, they leave.
+
+### 30. Writing about the previous version
+
+**Problem:** Documentation and comments should describe the current behavior. Mention the previous version only in change logs, release notes, migration guides, and other documents about change.
+**Before:**
+
+> This function was added to replace the previous approach of iterating through all items, which caused O(n²) performance.
+> **After:**
+> This function uses a hash map for O(1) lookups, avoiding the O(n²) cost of naive iteration.
+
+### 31. Forced punchlines and dramatic fragments
+
+**Problem:** AI writing often turns each sentence into a dramatic closing line. One short sentence can add emphasis. A row of short fragments usually feels forced.
+**Before:**
+
+> Then AlphaEvolve arrived. It had no preference for symmetry. No aesthetic prior. No nostalgia for human taste. The old rules were gone.
+> **After:**
+> AlphaEvolve changed the search because it did not favor symmetry or human-looking designs. That made some of the older assumptions less useful.
+
+### 32. Formulaic sayings
+
+**Words to watch:** X is the Y of Z, X becomes a trap, X is not a tool but a mirror, the language of, the currency of, the architecture of
+**Problem:** AI writing often turns an ordinary claim into a saying that sounds deep but adds no detail. Replace the saying with the specific claim.
+**Before:**
+
+> Symmetry is the language of trust. Efficiency becomes a trap when teams forget the human layer.
+> **After:**
+> Symmetric layouts often feel more predictable to users. Teams can over-optimize workflows and miss how people actually use them.
+
+### 33. Fake-candid openings
+
+**Phrases to watch:** Honestly?, Look, Here's the thing, The thing is, Let's be honest, Real talk, when used as standalone hooks or fake-candid pauses before an ordinary point.
+**Problem:** AI writing often starts with a staged pause or claim of honesty before making a routine point. State the point directly.
+**Before:**
+
+> Is it worth the price? Honestly? It depends on how often you'll use it.
+> **After:**
+> Whether it's worth the price depends on how often you'll use it.
+
+### 34. Answering objections no one raised
+
+**Phrases to watch:** This isn't (mainly/really) about, I'm not saying/arguing/trying to, To be clear, Don't get me wrong, This is not to say, You could argue/frame this differently but, Some might say... but
+**Problem:** AI writing may answer an objection that does not appear in the text. Watch for an unattributed statement about what the writer does not mean, especially when the topic appears nowhere else. A direct claim such as "the API is not thread-safe" is not this pattern.
+**Before:**
+
+> This isn't mainly about prompt length, and I'm not arguing that documentation doesn't matter. You could categorize the problem another way, but the issue is whether the agent can use the instruction when it acts.
+> **After:**
+> The issue is whether the agent can use the instruction when it acts.
+
+Remove only the unsupported defense. If it contains a real claim, state that claim directly. Keep an objection when the text names its source or answers it in full.
+
+### 35. Rejecting fake alternatives
+
+**Phrases to watch:** A tempting option/approach would be, One might be tempted to, An obvious approach would be, You might think... but, It would be easy to just, Some would suggest
+**Problem:** AI writing may introduce an option that no reader would consider, reject it in a clause, and never mention it again. This often leaves an old drafting idea in the final text. Remove the fake option and state the real constraint directly.
+**Before:**
+
+> Session tokens are rotated every 24 hours. A tempting approach would be to rotate them by restarting the auth service on a cron job, but that would drop every active session. Rotation happens in place, and clients refresh transparently.
+> **After:**
+> Session tokens are rotated every 24 hours, in place, and clients refresh transparently.
+
+One rejected option may be valid. Several short, unrelated rejections are a stronger sign. Ask what new information each sentence adds. If it only records an earlier edit, rewrite the paragraph around its main point.
+
+## Check for false positives
+
+### What not to flag
+
+A person may use some of these patterns. Do not treat any item below as proof by itself:
+
+- **Perfect grammar and consistent style.** Many writers are professionals or have been edited. Polish does not equal AI.
+- **Mixed casual and formal styles.** This can reflect the writer's field, age, or personal habits.
+- **"Bland" or "robotic" prose.** AI prose has _specific_ tells. Generic dryness without those tells is just dry writing.
+- **Formal or academic words.** §7 lists specific words that AI writing overuses. Do not simplify every formal word.
+- **Letter-style opening or closing on a comment.** Salutations and sign-offs predate ChatGPT by centuries.
+- **Common transition words in isolation.** _Additionally_, _moreover_, _consequently_ are AI-coded only when piled up. One _however_ is not a tell.
+- **Curly quotes alone.** macOS, Word, Google Docs, and most CMSes auto-curl by default. Curly quotes only count when stacked with other tells.
+- **Em dashes alone.** Many editors and journalists use them often. Em dashes are evidence only when paired with formulaic sales-y rhythm.
+- **One short sentence for emphasis.** Flag dramatic fragments only when several appear in a row.
+- **Deliberate repeated openings.** Writers may repeat an opening to build rhythm or pressure, as in "She came. She saw. She conquered." Change it only when the repetition adds nothing.
+- **"Honestly" or "look" mid-sentence.** These are ordinary in casual writing. The tell is the standalone theatrical opener, not the word itself.
+- **Useful limits and disclaimers.** Keep scope statements, legal and safety notices, real corrections, named objections, replies, and FAQ answers.
+- **Real alternatives.** Keep options that a reader may consider in a design document, tutorial, or argument. Remove only an unlikely option that the text dismisses and never uses again.
+- **Unsourced claims.** Most of the web is unsourced. Lack of citations doesn't prove anything.
+- **Correct, complex formatting.** Visual editors and templates produce clean output without any AI.
+- **Secondhand text.** Do not rewrite watched phrases inside quotations, titles, proper names, or examples where the phrase is being discussed rather than used.
+
+When unsure, look for several patterns together. One em dash proves nothing. Several stock patterns in the same passage are stronger evidence.
+
+### Human details to keep
+
+These details often carry the writer's voice. Keep them unless they hurt the meaning:
+
+- **Specific, unusual details.** Keep a real address, an odd quote, or a phrase such as "the lawyer who used to work upstairs from my dentist."
+- **Mixed feelings and unresolved tension.** Keep lines such as "I think this is mostly good, but it bothers me, and I can't fully explain why."
+- **Dated, era-bound references.** Slang, memes, or in-jokes that map to a specific year and subculture. Models lag by a year or more.
+- **Deliberate first-person choices.** Keep a cut or word choice when the writer can explain why it belongs.
+- **Variety in sentence length.** Real writing alternates short and long. AI writing tends toward an even, mid-length cadence.
+- **Genuine asides, parentheticals, or self-corrections.** "(I keep wanting to say 'almost' here, but it really was certain.)" Models rarely interrupt themselves like this.
+- **Edits made before November 30, 2022.** ChatGPT's public launch. Anything older than that is, with very rare exceptions, not AI-written.
+
+---
+
+## How to return the result
+
+**Pasted text (default).** Return the draft, a short list of remaining AI patterns, and the final rewrite.
+
+**File mode.** When the user names a file, run the full rewrite process but write only the final text to the file. Change prose only. Keep code blocks, YAML metadata, data, and link targets unchanged. Then give the user a short summary.
+
+**Embedded mode.** When another task uses this skill for a pull request, commit message, or document, return only the final text.
+
+## Rewrite process
+
+1. Read the source and mark each AI pattern.
+2. Write a draft. Read it aloud. Check the rhythm, details, simple verbs such as _is_ and _has_, and the right level of formality.
+3. Ask two questions:
+   - **"What still sounds AI-generated?"**
+   - **"Did the rewrite add or remove any fact, name, number, date, quote, citation, ranking, or other claim?"**
+     Treat any unsupported addition or lost claim as an error.
+4. Write the final version. State each point naturally instead of patching one flagged phrase at a time. If a sentence stays awkward, rewrite the paragraph around its main point. Apply the dash rule in §14.
+
+Return the result required by [How to return the result](#how-to-return-the-result).
+
+## Source
+
+This skill is based on [Wikipedia: Signs of AI writing](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing), maintained by WikiProject AI Cleanup. Its patterns come from reviews of AI-generated text on Wikipedia.
+
+Wikipedia's main point: "LLMs use statistical algorithms to guess what should come next. The result tends toward the most statistically likely result that applies to the widest variety of cases."

+
+# i-have-adhd
+
+The reader has ADHD. Output is not just brief. It is shaped so an ADHD brain can act on it.
+
+## Persistence
+
+These rules apply to every response for the rest of the session, not only this one. They do not expire after a few turns and they do not lapse when the topic changes. If you are unsure whether they still apply, they do.
+
+Turn them off only when the reader says "stop adhd mode" or "normal mode". Confirm in one line, then return to your default style.
+
+## What ADHD changes about reading
+
+Five facts drive every rule below:
+
+1. Working memory is small. Anything not on screen is forgotten. Do not ask the reader to "keep in mind X."
+2. Knowing the answer is not doing the answer. The friction between "got it" and "done it" is where work dies.
+3. Starting is the hardest step. The first action must be obvious, small, and doable now.
+4. Time estimates feel uniform. "A bit of work" and "a few hours" register the same. Vague estimates fail.
+5. Dopamine is scarce. Visible progress matters. Buried wins do not register.
+
+## Rules
+
+### 1. Lead with the next action
+
+The first line is something the reader can do. Not context. Not a plan. The action.
+
+Bad: "Let's think about this. Your auth flow has a few moving pieces..."
+Good: "Run `npm install jsonwebtoken`, then edit `src/auth.ts:42`."
+
+If the answer is a command, path, or snippet, it goes first. Prose comes after, if at all.
+
+### 2. Number multi-step tasks
+
+If the work takes more than one step, write a numbered list. Each step is one bounded action. No step contains "and then" twice.
+
+Use the fewest steps that still work. Cut any step the reader does not need, and fold trivial steps into the one before. A short path finished beats a complete path abandoned.
+
+Bad: "First open the file, find the function, swap it out, then run the tests."
+
+Good:
+
+```
+1. Open `src/auth.ts`
+2. Replace `verifyToken` (lines 42 to 58) with the snippet below
+3. Run `npm test -- auth.spec.ts`
+```
+
+### 3. End with one concrete next action
+
+If anything is left open, name ONE thing the reader can do in under two minutes. Even "open the file" counts.
+
+Bad: "Hope that helps. Let me know if you want to dig deeper."
+Good: "Next: run `npm test` and paste the first failing line."
+
+### 4. Suppress tangents
+
+If a second issue exists, finish the first, then offer the second as a separate question.
+
+Bad: "Here's the fix. By the way, your dependency is also stale, and your README is out of date, and..."
+Good: "Here's the fix. Separately: there is also a stale dependency. Want me to handle that next?"
+
+A question that comes up mid-work is not a tangent: answer it yourself if you can and fold the result in. If it still needs the reader, surface it once, at the end.
+
+### 5. Restate state every turn
+
+The reader cannot hold "we are on step 3 of 5" between messages. Restate it.
+
+Bad: "Done. Ready for the next part?"
+Good: "Step 3 of 5 done: schema updated. Next: backfill the new column. Run the script?"
+
+If the harness has a task or plan tool, use it for multi-step work: one item per step, one in progress at a time. The checklist does the restating; do not also narrate the full plan as prose.
+
+### 6. Give specific time estimates
+
+Vague estimates fail. Ballpark in concrete units.
+
+Bad: "This will take some work."
+Good: "About 15 minutes if tests already cover this. An afternoon if not."
+
+### 7. Make completed work visible
+
+Show what now works, in concrete terms. Do not bury wins in a recap.
+
+Bad: "I've made some changes to the auth flow. Among other things..."
+Good: "Login now works with magic links. Try: `npm run dev`, open `/login`."
+
+### 8. Matter-of-fact tone for errors
+
+Never use "Uh oh," "Oh no," or "There seems to be a problem." State cause and fix.
+
+Bad: "Uh oh, the test is failing. There seems to be an issue..."
+Good: "Test fails at `auth.spec.ts:42`: expected 200, got 401. Cause: missing auth header. Fix: add `Authorization: Bearer ${token}` to the request."
+
+### 9. Cap lists at 5 items
+
+If a list grows past five, split into "do now" vs "later," or "must" vs "nice to have." Five items ranked beats ten unranked.
+
+### 10. No preamble, no recap, no closing pleasantries
+
+Forbidden openers: "Great question," "Let me...", "I'll...", "Sure!", "Looking at your...", "To answer your question..."
+
+Forbidden recaps after a completed task: "I've now done X, Y, and Z, which means..."
+
+Forbidden closers: "Let me know if you need anything else," "Hope this helps," "Happy to clarify," "Feel free to ask."
+
+Start with the answer. End when the answer is done.
+
+## When to break the rules
+
+Override the defaults when:
+
+1. User asks to "explain" or "walk me through." Explain fully. Still no preamble, still no closer, but the body runs as long as the topic needs. Add headers so the reader can skim back.
+2. Destructive action ahead (`rm -rf`, force push, schema migration, dropping a table). Confirm before acting. Safety wins over brevity.
+3. Debug spiral. If the last three turns have been "still broken," stop iterating on code. Name the assumption that might be wrong. Ask one diagnostic question.
+4. Real ambiguity in the request. One short clarifying question beats guessing and rewriting.
+5. A rule fights the task. When a rule would delete the answer itself, the task wins; the shape stays. Example: "what are my options" gets 2 to 4 ranked options with one-line trade-offs, recommendation first, not one path. The options are the answer.
+6. A rule fights the harness. Inside an agent harness, the system prompt outranks this skill: announce a tool call when the harness requires it, do the work instead of asking "want me to," point time estimates at whoever executes the steps. Same principle as 5: the constraint wins, the shape stays.
+
+## Pre-send check
+
+Before sending, delete:
+
+1. The first sentence if it announces what you are about to do.
+2. The last sentence if it asks "anything else?" or recaps what just happened.
+3. Any "by the way" sidebar.
+4. Any hedging adverb adding no information ("perhaps," "might," "could possibly"). Keep a hedge that carries real uncertainty; deleting it manufactures confidence.
+5. Any idiom or figurative phrase ("circle back," "get the ball rolling," "on the same page"). Replace with the literal action.
+
+Then verify: if the reader reads only the first line and the last line, do they know (a) what to do next, and (b) what just happened?
+
+If yes, send.

+description: Report open pull requests in the current or requested GitHub repository, ranked by merge confidence (0-100), combining CI and review metadata with an initial diff review.
+---
+
+Report the selected author's open pull requests, ranked by merge confidence (0-100). This skill reports readiness; it does not merge pull requests.
+
+## Resolve scope
+
+Use the repository and author requested by the user. Otherwise resolve the repository from the current checkout and default the author to the authenticated GitHub user:
+
+```bash
+repo=$(gh repo view --json nameWithOwner --jq .nameWithOwner)
+author=$(gh api user --jq .login)
+```
+
+Stop if either lookup fails. If no repository can be resolved, ask for its `owner/repo`. Do not substitute a fixed repository or username. Reuse the resolved scope for every command; when the user supplies it, assign those values instead of running the defaults above.
+
+## Collect readiness
+
+```bash
+gh pr list --author "$author" --state open --limit 100 -R "$repo" --json number,url,title,baseRefName,headRefName,headRefOid,isDraft,reviewDecision,mergeable,mergeStateStatus,changedFiles,additions,deletions
+```
+
+If the list reaches 100 results, paginate before claiming complete coverage. If merge states are `UNKNOWN`, retry after about 30 seconds with a bounded retry count; report unresolved states as unknown.
+
+Inspect each PR's current reviews and checks:
+
+```bash
+gh pr view <number> -R "$repo" --json latestReviews,reviewDecision,statusCheckRollup,mergeable,mergeStateStatus
+gh pr checks <number> -R "$repo" --required
+```
+
+Use GitHub's `reviewDecision` and the repository's applicable review requirements. A blank decision does not prove approval is needed or satisfied. Consult current reviews and branch protection or rulesets when needed and accessible. An individual approval, including a bot approval, does not by itself prove all required reviews are satisfied. Report unavailable requirements as unknown.
+
+Group PRs into:
+
+- Merge Now: non-draft, conflict-free PRs whose required checks and reviews are satisfied and whose GitHub merge state permits merging.
+- Almost There: PRs waiting on checks or a lower PR in a stack. Resolve stack dependencies from head/base refs and show them in dependency order; recheck followers after their base changes.
+- Needs Review: required approvals are missing or changes were requested.
+- Blocked / Drafts / Unknown: failing checks, conflicts, drafts, other unmet requirements, or unavailable readiness data. State the specific reason.
+
+## Review and score
+
+Start with a metadata baseline: tiny metadata-only diffs 95-98; small tested fixes 85-94; bigger, novel, or infrastructure changes 75-84. Missing required approval caps the score around 70, conflicts around 45-72, and drafts around 40-60. These are subjective confidence scores, not probabilities or substitutes for merge requirements.
+
+Fetch the diff for an initial review:
+
+```bash
+gh pr diff <number> -R "$repo" --patch
+```
+
+Check for breaking changes, removed exports still referenced, API changes, migrations, authentication and billing risks, performance-sensitive paths, caching, sensitive values in logs, and test coverage for behavior changes. Read the repository's own guidance for project-specific constraints. Lower the score for concrete risks and include the review verdict in the rationale.
+
+Only repeat the diff review for new PRs or changed `headRefOid` values. Reuse unchanged diff verdicts, but refresh CI, reviews, merge state, and the resulting score every run. If the diff is unavailable, label the score metadata-only and explain the limitation.
+
+## Report
+
+Return a ranked list with one bullet per PR: score, readiness group, one-line rationale, and a Markdown link using the PR's returned `url`. Flag newly merged or closed PRs and new PRs since the previous run. Verify the state of previously tracked PRs before calling them merged or closed; disappearance from the list alone is not sufficient.
+
+Report once per invocation. If a recurring monitor invokes this skill, follow its configured notification policy and cadence.

+description: Carry a change through implementation, a bounded thermo-nuclear review fix loop, recorded end-to-end proof, visual PR documentation, CI, and review resolution. Use when asked to ship a change with proof or finish an existing PR through its evidence and review gates; does not merge the PR.
+---
+
+# Ship With Proof
+
+Take one scoped change from implementation to a reviewable PR with evidence that the new behavior works and an adjacent flow still works. Run the chain in the current session. Creating the PR is an intermediate milestone, not completion. Do not merge it.
+
+## Resolve scope and dependencies
+
+Use the current or requested repository and its agent guidance, PR template, testing conventions, and verification commands. Accept an existing PR and reuse it; search for a matching PR before creating one. Do not assume a repository name, package manager, default branch, reviewer, review bot, messaging channel, or browser host.
+
+Infer the flow to exercise from the task and diff. Ask only when a missing choice affects the work: the intended behavior, a non-obvious proof flow, the required reviewer, or an external destination. Preserve caller-required PR sections, evidence markers, and artifacts.
+
+Use these skills for their respective work:
+
+- `$git-commit` for scoped commits, and `$gh-stack` when the repository requires or already uses a stack.
+- `$thermo-nuclear-code-quality-review` for each complete review pass; `$thermo-nuclear-review-fix-loop` for repair discipline, subject to this workflow's four-round limit.
+- `$create-pr`, `$show-me`, and `$code-diagram-html` for visual PR documentation, subject to the evidence delivery rules below.
+- The repository's end-to-end testing and review-thread resolution skills when available. Otherwise use its documented test commands, available recording tools, and GitHub review APIs.
+
+Load dependencies when their step begins. Identify a missing skill rather than pretending it ran. Continue independent work while resolving the missing dependency. This workflow does not assume a particular agent platform.
+
+## Implement and test
+
+Implement the smallest complete change that satisfies the task. Preserve unrelated work, response contracts, and error precedence unless changing them is part of the request. Run the repository's required checks before committing. Keep each stack layer independently reviewable and explain only that layer's delta in its PR.
+
+Add or extend tests that distinguish the defect from the fix and cover unchanged inputs. Do not weaken assertions or remove coverage to hide a failure. When an intentional behavior change requires updating an existing expectation, explain that change and preserve the relevant regression coverage. For changes with no executable behavior, state why unit coverage is inapplicable rather than inventing a test.
+
+Create or update the PR with a conventional title and the required content. Its body must include a standalone `## Show me` section with one or two compact GitHub-renderable blocks from `$show-me`: a diff, pseudocode, call or component tree, or Mermaid diagram grounded in real names and paths.
+
+## Run the thermo loop
+
+Review the entire scoped diff and relevant surrounding code, fix actionable findings, run verification, commit and push fixes, then review the updated diff again. A pass must not be limited to checking earlier findings.
+
+An actionable finding identifies a structural problem introduced by the change with a repair inside the agreed scope. Record reasoned refutations. Explicitly defer findings that require unrelated work, a new architectural layer, or a product decision; do not silently expand the PR or count a deferred issue as fixed.
+
+Record each round under `## Thermo-nuclear fix loop`, including the reviewed head, findings, fixes or reasoned dispositions, and verification. Keep the final empty result visible when the loop terminates cleanly.
+
+Stop after four review rounds if findings remain. Document the remaining findings and report the gate as incomplete; the cap is a stopping condition, not permission to claim a clean review. This limit takes precedence over the loop skill's default unbounded repetition. Do not create a separate goal unless the user or host instructions authorize one.
+
+## Capture proof early
+
+As soon as the thermo loop is clean, capture end-to-end proof. Do not wait for CI or an asynchronous reviewer. The recording must show both the changed behavior and at least one adjacent pre-existing flow that the diff could plausibly break.
+
+Use the repository's test environment and available recording tools. Annotate test starts and assertions using `test_start` and `assertion` markers when supported, or equivalent visible labels and a timestamped test log. Record the tested commit and exact scenario. Avoid exposing credentials or private user data in recordings and logs.
+
+A recording with a failed assertion, stuck state, error, or broken layout is a finding. Fix the problem, rerun relevant checks, and record again from scratch. Substantive fixes return through the thermo gate.
+
+For API-only, CLI, or backend changes without a meaningful visual surface, use an end-to-end run and captured request/response or structured log evidence instead of an empty browser recording. State what it proves and why video is inapplicable. If the needed runtime, credentials, or capture tool is unavailable, report that gate as blocked; screenshots alone do not establish an interaction sequence.
+
+## Build and deliver the visual explanation
+
+Use `$code-diagram-html` and `$show-me` to produce a self-contained `<change-slug>-<date>.html` explaining the defect and fix, or the new behavior and affected flow. Include the relevant before/after shape, decisive tests, thermo results, and evidence links. For performance changes, show measured before/after values with workload and iteration count. Every measurement must be traceable to captured output from this run; never invent numbers to fill a chart.
+
+Use inline CSS and SVG, no network assets or build step. Follow the project's visual conventions or the HTML skill's neutral defaults. Verify desktop and narrow layouts. Render the page at approximately 2x scale with an available browser tool, inspect the PNG, and split tall images if that is needed for readable text.
+
+Do not commit generated evidence HTML, PNGs, or recordings. Upload through an authorized, supported artifact mechanism that gives reviewers usable URLs. Check access and link validity. If no such mechanism is available, retain local evidence and report the delivery gate as blocked; never manufacture a URL or assume a local Markdown path uploads a file.
+
+Put the HTML URL and uploaded PNGs under a separate `## Visualization` section. GitHub does not render arbitrary HTML or inline SVG in PR bodies. Keep the `## Show me` blocks readable independently of the attachment. For a change too small to benefit from an HTML artifact, state the reason in the PR; the inline visual remains required.
+
+Post the recording or equivalent backend evidence and key screenshots together in one PR comment, describing which flow each item proves. Use actual uploaded URLs. Send the user the PR and evidence links at this milestone, before waiting for reviewer approval. Do not use collapsible sections in the PR body or evidence comments.
+
+## Finish CI and review
+
+Inspect checks and failing job logs with the available GitHub tools. Fix failures attributable to the change and report unrelated infrastructure failures accurately. Address every actionable review thread with a fix or a reasoned response. Resolve a thread only when it has actually been addressed and repository conventions permit it.
+
+Use the reviewer or review process selected by the user or required by the repository. Never hardcode a bot or treat one named reviewer's approval as satisfying all branch rules. If approval is required but no reviewer can be identified, ask while continuing evidence and CI work.
+
+Request review through the normal PR mechanism. Messages to Slack or another external channel require explicit authorization for that destination; this skill does not grant it. Keep one review conversation and avoid duplicate pings. Handle feedback in this session; do not launch a separate babysitter that can push concurrent branch changes.
+
+Fix or refute comments, push scoped commits, rerun affected checks, and request re-review only when needed. Stop pinging after approval. If a reviewer is unavailable, authorization is missing, or an external service remains blocked, preserve the current state and report the exact outstanding gate rather than waiting or retrying indefinitely. Do not configure a recurring monitor unless requested.
+
+## Keep evidence current
+
+A late behavior change invalidates evidence for the path it touches. Re-run that proof, and repeat thermo review for substantive code changes. Refresh CI and review status after every push. Evidence may come from an earlier commit only when its covered behavior still matches the final head; explain that relationship rather than claiming it was recorded on the final commit.
+
+Complete means required CI is green, required approvals are current, review threads are addressed, the thermo loop is clean, and the PR carries valid proof and visual documentation. An exhausted review budget or blocked gate must be reported as incomplete.
+
+Return the PR link, final head, CI and approval states, thermo result, HTML and image links or the justified small-change exception, recording or equivalent evidence URL, and anything not tested with its reason. If another caller owns the final report, hand it those facts. Never merge as part of this skill.

+
+Help the user understand the current topic of conversation visually. Skip the preamble and keep prose brief. Pick the smallest view that makes the key point clear.
+
+- Show logic or an algorithm as pseudocode:
+
+```text
+on(save)
+  if content is unchanged
+    return cached result
+  write new content
+  return fresh result
+```
+
+- Show runtime control flow as a call tree:
+
+```text
+submitForm
+  createSession
+    persistPrompt
+    launchAgent
+  navigateToSession
+```
+
+- Show UI structure as a component tree, including state and module boundaries that matter:
+
+```tsx
+<SessionPage> (apps/example/src/routes/session.tsx)
+  useSessionEvents()
+  <SessionToolbar>
+    <RunSkillButton> (packages/ui)
+```
+
+- Show file responsibility or a broad refactor as a shallow file tree:
+
+```text
+src/
+├── commands/       # parses user actions
+├── sessions/       # owns session state
+└── transport/      # sends API requests
+```
+
+- Show component interaction, control flow, or data flow with Mermaid:
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant UI
+    participant Daemon
+    User->>UI: choose command
+    UI->>Daemon: send expanded prompt
+    Daemon-->>UI: stream result
+```
+
+- Use `diff` when the point is what changes and the surrounding shape already exists. Match the diff shape to the topic.
+
+For a component change:
+
+```diff
+ <SessionPage>
+   useSessionEvents()
+   <SessionToolbar>
++    <RunSkillButton />
+   <SessionTimeline>
++    <SkillResultCard />
+```
+
+For a file-layout change:
+
+```diff
+ src/
+ ├── commands/
++│   └── show-me.ts       # expands the slash command
+ ├── sessions/
+-└── transport.ts
++└── transport/
++    ├── client.ts
++    └── stream.ts
+```
+
+For a call-tree or call-stack change:
+
+```diff
+ submitForm
+   createSession
+     persistPrompt
++    expandSkillMention
+     launchAgent
+-  navigateToSession
++  navigateToSession
++    subscribeToEvents
+```
+
+For a state or control-flow change:
+
+```diff
+ on(save)
+-  write content
++  if content is unchanged
++    return cached result
++  write new content
++  invalidate cache
+```
+
+- Show the whole block when most of it is new, when omitted context would hide ownership or order, or when the user needs a copyable target shape:
+
+```ts
+function expandSkill(command: string): string {
+  const skillName = command.slice(1)
+  return `use the ${skillName} skill`
+}
+```
+
+- For a visual UI, layout, state comparison, or concept too dense for Mermaid, write one focused HTML file — a diagram, an infographic, or a short slide deck, whichever fits the point. Match the product's colors, type, spacing, and components; use real labels and data; support desktop and mobile. Then open it for the user:
+
+```
+Bash(open path/to/show-me-{description}.html)
+```
+
+### guidance
+
+Place each visual next to the short text it supports. Keep only the calls, files, props, states, and boundaries needed to answer the user's current question or the options to resolve the current discussion point.
+
+You may use one of these, you may use several, it is unlikely you will use all of them. Use your judgement and don't overwhelm the user.

+
+# Thermo-Nuclear Code Quality Review
+
+Use this skill for an unusually strict review focused on implementation quality, maintainability, abstraction quality, and codebase health.
+
+Above all, this skill should push the reviewer to be **ambitious** about code structure. Do not merely identify local cleanup opportunities. Actively search for "code judo" moves: restructurings that preserve behavior while making the implementation dramatically simpler, smaller, more direct, and more elegant.
+
+## Core Prompt
+
+Start from this baseline:
+
+> Perform a deep code quality audit of the current branch's changes.
+> Rethink how to structure / implement the changes to meaningfully improve code quality without impacting behavior.
+> Work to improve abstractions, modularity, reduce Spaghetti code, improve succinctness and legibility.
+> Be ambitious, if there is a clear path to improving the implementation that involves restructuring some of the codebase, go for it.
+> Be extremely thorough and rigorous. Measure twice, cut once.
+
+## Non-Negotiable Additional Standards
+
+Apply the baseline prompt above, plus these explicit review rules:
+
+0. **Be ambitious about structural simplification.**
+   - Do not stop at "this could be a bit cleaner."
+   - Look for opportunities to reframe the change so that whole branches, helpers, modes, conditionals, or layers disappear entirely.
+   - Prefer the solution that makes the code feel inevitable in hindsight.
+   - Assume there is often a "code judo" move available: a re-organization that uses the existing architecture more effectively and makes the change dramatically simpler and more elegant.
+   - If you see a path to delete complexity rather than rearrange it, push hard for that path.
+
+1. **Do not let a PR push a file from under 1k lines to over 1k lines without a very strong reason.**
+   - Treat this as a strong code-quality smell by default.
+   - Prefer extracting helpers, subcomponents, modules, or local abstractions instead of letting a file sprawl past 1000 lines.
+   - If the diff crosses that threshold, explicitly ask whether the code should be decomposed first.
+   - Only waive this if there is a compelling structural reason and the resulting file is still clearly organized.
+
+2. **Do not allow random spaghetti growth in existing code.**
+   - Be highly suspicious of new ad-hoc conditionals, scattered special cases, or one-off branches inserted into unrelated flows.
+   - If a change adds "weird if statements in random places", treat that as a design problem, not a stylistic nit.
+   - Prefer pushing the logic into a dedicated abstraction, helper, state machine, policy object, or separate module instead of tangling an existing path.
+   - Call out changes that make the surrounding code harder to reason about, even if they technically work.
+
+3. **Bias toward cleaning the design, not just accepting working code.**
+   - If behavior can stay the same while the structure becomes meaningfully cleaner, push for the cleaner version.
+   - Do not rubber-stamp "it works" implementations that leave the codebase messier.
+   - Strongly prefer simplifications that remove moving pieces altogether over refactors that merely spread the same complexity around.
+
+4. **Prefer direct, boring, maintainable code over hacky or magical code.**
+   - Treat brittle, ad-hoc, or "magic" behavior as a code-quality problem.
+   - Be skeptical of generic mechanisms that hide simple data-shape assumptions.
+   - Flag thin abstractions, identity wrappers, or pass-through helpers that add indirection without buying clarity.
+
+5. **Push hard on type and boundary cleanliness when they affect maintainability.**
+   - Question unnecessary optionality, `unknown`, `any`, or cast-heavy code when a clearer type boundary could exist.
+   - Prefer explicit typed models or shared contracts over loosely-shaped ad-hoc objects.
+   - If a branch relies on silent fallback to paper over an unclear invariant, ask whether the boundary should be made explicit instead.
+
+6. **Keep logic in the canonical layer and reuse existing helpers.**
+   - Call out feature logic leaking into shared paths or implementation details leaking through APIs.
+   - Prefer existing canonical utilities/helpers over bespoke one-offs.
+   - Push code toward the right package, service, or module instead of normalizing architectural drift.
+
+7. **Treat unnecessary sequential orchestration and non-atomic updates as design smells when the cleaner structure is obvious.**
+   - If independent work is serialized for no good reason, ask whether the flow should run in parallel instead.
+   - If related updates can leave state half-applied, push for a more atomic structure.
+   - Do not over-index on micro-optimizations, but do flag avoidable orchestration complexity that makes the implementation more brittle.
+
+## Primary Review Questions
+
+For every meaningful change, ask:
+
+- Is there a "code judo" move that would make this dramatically simpler?
+- Can this change be reframed so fewer concepts, branches, or helper layers are needed?
+- Does this improve or worsen the local architecture?
+- Did the diff add branching complexity where a better abstraction should exist?
+- Did a previously cohesive module become more coupled, more stateful, or harder to scan?
+- Is this logic living in the right file and layer?
+- Did this change enlarge a file or component past a healthy size boundary?
+- Are there repeated conditionals that signal a missing model or missing helper?
+- Is the implementation direct and legible, or does it rely on special cases and incidental control flow?
+- Is this abstraction actually earning its keep, or is it just a wrapper?
+- Did the diff introduce casts, optionality, or ad-hoc object shapes that obscure the real invariant?
+- Is this logic living in the canonical layer, or did the diff leak details across a boundary?
+- Is this orchestration more sequential or less atomic than it needs to be?
+
+## What to Flag Aggressively
+
+Escalate findings when you see:
+
+- A complicated implementation where a cleaner reframing could delete whole categories of complexity.
+- Refactors that move code around but fail to reduce the number of concepts a reader must hold in their head.
+- A file crossing 1000 lines due to the PR, especially if the new code could be split out.
+- New conditionals bolted onto unrelated code paths.
+- One-off booleans, nullable modes, or flags that complicate existing control flow.
+- Feature-specific logic leaking into general-purpose modules.
+- Generic "magic" handling that hides simple structure and makes the code harder to reason about.
+- Thin wrappers or identity abstractions that add indirection without simplifying anything.
+- Unnecessary casts, `any`, `unknown`, or optional params that muddy the real contract.
+- Copy-pasted logic instead of extracted helpers.
+- Narrow edge-case handling implemented in the middle of an already busy function.
+- Refactors that technically pass tests but make the code less modular or less readable.
+- "Temporary" branching that is likely to become permanent debt.
+- Bespoke helpers where the codebase already has a canonical utility for the job.
+- Logic added in the wrong layer/package when it should live somewhere more central.
+- Sequential async flow where obviously independent work could stay simpler and clearer with parallel execution.
+- Partial-update logic that leaves state less atomic than necessary.
+
+## Preferred Remedies
+
+When you identify a code-quality problem, prefer suggestions like:
+
+- Delete a whole layer of indirection rather than polishing it.
+- Reframe the state model so conditionals disappear instead of getting centralized.
+- Change the ownership boundary so the feature becomes a natural extension of an existing abstraction.
+- Turn special-case logic into a simpler default flow with fewer exceptions.
+- Extract a helper or pure function.
+- Split a large file into smaller focused modules.
+- Move feature-specific logic behind a dedicated abstraction.
+- Replace condition chains with a typed model or explicit dispatcher.
+- Separate orchestration from business logic.
+- Collapse duplicate branches into a single clearer flow.
+- Delete wrappers that do not meaningfully clarify the API.
+- Reuse the existing canonical helper instead of introducing a near-duplicate.
+- Make type boundaries more explicit so the control flow gets simpler.
+- Move the logic to the package/module/layer that already owns the concept.
+- Parallelize independent work when that also simplifies the orchestration.
+- Restructure related updates into a more atomic flow when partial state would be harder to reason about.
+
+Do not be satisfied with "maybe rename this" feedback when the real issue is structural.
+Do not be satisfied with a merely cleaner version of the same messy idea if there is a plausible path to a much simpler idea.
+
+## Review Tone
+
+Be direct, serious, and demanding about quality.
+Do not be rude, but do not soften major maintainability issues into mild suggestions.
+If the code is making the codebase messier, say so clearly.
+If the implementation missed an opportunity for a dramatic simplification, say that clearly too.
+
+Good phrases:
+
+- `this pushes the file past 1k lines. can we decompose this first?`
+- `this adds another special-case branch into an already busy flow. can we move this behind its own abstraction?`
+- `this works, but it makes the surrounding code more spaghetti. let's keep the behavior and restructure the implementation.`
+- `this feels like feature logic leaking into a shared path. can we isolate it?`
+- `this abstraction seems unnecessary. can we just keep the direct flow?`
+- `why does this need a cast / optional here? can we make the boundary more explicit instead?`
+- `this looks like a bespoke helper for something we already have elsewhere. can we reuse the canonical one?`
+- `i think there's a code-judo move here that makes this much simpler. can we reframe this so these branches disappear?`
+- `this refactor moves complexity around, but doesn't really delete it. is there a way to make the model itself simpler?`
+
+## Output Expectations
+
+Prioritize findings in this order:
+
+1. Structural code-quality regressions
+2. Missed opportunities for dramatic simplification / code-judo restructuring
+3. Spaghetti / branching complexity increases
+4. Boundary / abstraction / type-contract problems that make the code harder to reason about
+5. File-size and decomposition concerns
+6. Modularity and abstraction issues
+7. Legibility and maintainability concerns
+
+Do not flood the review with low-value nits if there are larger structural issues.
+Prefer a smaller number of high-conviction comments over a long list of cosmetic notes.
+
+## Approval Bar
+
+Do not approve merely because behavior seems correct.
+The bar for approval is:
+
+- no clear structural regression
+- no obvious missed opportunity to make the implementation dramatically simpler when such a path is visible
+- no unjustified file-size explosion
+- no obvious spaghetti-growth from special-case branching
+- no obviously hacky or magical abstraction that makes the code harder to reason about
+- no unnecessary wrapper/cast/optionality churn obscuring the real design
+- no clear architecture-boundary leak or avoidable canonical-helper duplication
+- no missed opportunity for an obvious decomposition that would materially improve maintainability
+
+Treat these as presumptive blockers unless the author can justify them clearly:
+
+- the PR preserves a lot of incidental complexity when there is a plausible code-judo move that would delete it
+- the PR pushes a file from below 1000 lines to above 1000 lines
+- the PR adds ad-hoc branching that makes an existing flow more tangled
+- the PR solves a local problem by scattering feature checks across shared code
+- the PR adds an unnecessary abstraction, wrapper, or cast-heavy contract that makes the design more indirect
+- the PR duplicates an existing helper or puts logic in the wrong layer when there is a clear canonical home
+
+If those conditions are not met, leave explicit, actionable feedback and push for a cleaner decomposition.

+
+# Thermo-Nuclear Review Fix Loop
+
+1. Create a goal to run `$thermo-nuclear-code-quality-review` on the scoped changes, fix every actionable finding, repeat full reviews until clean, and complete the required verification. If an active goal already covers this exact objective, continue it instead of creating a duplicate.
+2. Load and apply `$thermo-nuclear-code-quality-review` in full. Review the entire current diff and relevant surrounding code, not only the last files changed.
+3. Fix every actionable finding while preserving unrelated work and behavior. Run the relevant scoped tests and repository-required verification after each fix pass.
+4. Run another complete thermo-nuclear review from the updated state. Do not limit subsequent passes to checking whether earlier findings were fixed.
+5. Repeat review, fix, and verification passes until a complete fresh review returns zero actionable findings. Do not stop merely because one pass was completed or because no new findings appeared while old findings remain.
+6. When the review is clean and verification passes, mark the goal complete. Report the number of review passes, the findings fixed, and the verification performed.
+
+If progress genuinely requires user input or new authority, report the exact blocker without claiming the loop is complete.
