Intent

Prompts behave differently on different models, so a result from one agent and model says little about another. This change publishes which agent and model combinations the companion's evaluation has been tested with and how each scored, and warns the reviewer who picks a combination that was never tested.

The evaluation output lists every tested combination with its agent, agent version, model, effort, run date and scores. The README links to the current list. Choosing an untested combination in the settings shows a clear, non-blocking warning: every review still runs and its results stay stamped with who answered.

Validation never launches or installs the VS Code application or any tool. Extension tests that need VS Code run only in CI, so live validation goes through the engine protocol, the unit tests and rendered output.

Closes #3.

What Changed

  • Added TESTED_MODELS and isTestedModel() to the engine, recording every agent, model and effort combination the evaluation has run with its version, run date and scores, and published the list as the new docs/tested-models.md page linked from the README.
  • The evaluation now derives testedCombinations() from a run's stamped results and prints one TESTED line per combination (agent, version, model, effort, run date, per-prompt scores) in its report, leaving out model-free or model-unnamed runs.
  • The extension shows a non-blocking warning when the settings pick an untested combination — once at activation and whenever second-look.agent or second-look.agentModel changes — names the tested models and the published page, and carries the warning in the status bar tooltip.

Risk Assessment

✅ Low: The change is well-bounded — a published constant and predicate in the engine, a derived listing in the evaluation report, and a non-blocking settings warning in the extension — with behavioral tests, docs that faithfully mirror the recorded baseline, and all three acceptance criteria satisfied; the only observation is a documented deliberate tradeoff.

Testing

Drove the real evaluation CLI three times against a disposable scripted Pi stand-in over a throwaway copy of the example-7 case: the report prints a TESTED line carrying the agent, version, model, effort, run date and per-prompt scores, while a run whose agent never named its model and a model-free run print none. The README's links to docs/tested-models.md resolve and the published page matches the built engine's TESTED_MODELS field-by-field and score-by-score, rendered as an HTML artifact. The settings warning was exercised only through the intent's sanctioned local routes — 78 targeted unit tests plus a reviewer-journey driver running the real extension code (activate, configuration listener, status bar) against the repository's VS Code test double, with a rendered artifact of the exact warning and tooltip strings — because the ticket's standing boundary forbids launching VS Code on this machine; since these routes are not a live drive of the real product, that scenario is reported untested and its non-live corroboration is preserved in the artifacts. UI-facing evidence is rendered HTML rather than screenshots for that reason. No failures; transient fixtures removed and the worktree left clean.

  • ℹ️ packages/extension/src/agent-settings.ts:104 - When second-look.agentModel is empty (the default) and the agent has any tested model, untestedModelWarning stays quiet even if the agent's actual default model differs from the tested one, so a fresh install can run an untested combination with no warning. This is a deliberate, documented tradeoff (the settings cannot name the agent's default model without probing it; the run stamp discloses what answered), recorded here only to acknowledge it was examined.

An evaluation run with an agent prints a TESTED line listing the combination's agent, agent version, model, effort, run date and its scores ✅ pass live Live drive of the real CLI (node packages/evaluation/dist/main.js run --cases <throwaway example-7 copy> --agent pi) with a disposable scripted pi stand-in on PATH; artifact eval-run-tested-line.txt…
A run whose agent ended before naming its model, and a model-free run, list no tested combination (boundary of the listing) ✅ pass live Two live CLI drives: FAKE_PI_NO_MODEL=1 (rows printed as '[pi 9.9.9 unknown model]', zero TESTED lines — eval-run-unnamed-model.txt) and a --model-free run over example-42 (zero TESTED lines — eval-ru…
The README links to the current list of tested models, and the published page lists what the engine's TESTED_MODELS publishes (agent, version, model, effort, run date, every score) ✅ pass live verify-docs.mjs resolved the README's markdown links (2 in README.md, 1 in packages/evaluation/README.md, all targets existing) and executed the built engine package to read TESTED_MODELS, checking ev…
Choosing an untested agent/model combination in settings shows a clear, non-blocking warning naming the tested combinations and the published list, while tested choices stay quiet ⏸️ untested no The prior payload did not establish a live result for this scenario: it recorded only unit tests and a reviewer-journey driver over the repository's VS Code test double, which are not a drive against…
