Scrutineer (model_proxy_cli_integration_test.go) and tamis (runner_integration_test.go, twice) each hand-roll the same Anthropic SSE fake, and tamis adds the Responses function call and the ChatGPT startup routes. Claude Code 2.1 and Codex 0.166.0 run the tool call and finish the turn against these replies.

Summary by CodeRabbit

• New Features
  • Added helpers that return streamed Anthropic text and tool-use responses, OpenAI-compatible function-call responses, and fixture responses for recognized Codex startup requests. Anthropic replies receive distinct message IDs.
• Documentation
  • Added README guidance describing the helpers and their use with a CLI through the proxy.

Walkthrough

The modelproxytest package adds helpers for Anthropic and Responses API streams, plus JSON responses for three Codex startup routes. Tests validate event framing, payloads, message IDs, and route handling. The README documents the helpers.

Changes: Proxy test response helpers

Layer / File(s)	Summary
Streaming API responses modelproxy/modelproxytest/modelproxytest.go, modelproxy/modelproxytest/modelproxytest_test.go, README.md	Anthropic text and tool-use helpers and a Responses API function-call helper emit server-sent events. Tests check event framing, payloads, and distinct Anthropic message IDs. The README documents these helpers.
Codex startup route responses modelproxy/modelproxytest/modelproxytest.go, modelproxy/modelproxytest/modelproxytest_test.go	CodexStartup writes JSON responses for three recognized routes and returns false without writing a body for other paths. Tests cover three handled routes and one unhandled route.

Full details: Title check

Explanation

The title names the main change: a new modelproxytest package that provides the replies a fake model upstream streams to a real CLI. The raw summary confirms this. It adds modelproxytest.go with AnthropicText, AnthropicToolUse, ResponsesFunctionCall, and CodexStartup, plus tests and README documentation. The title is specific and matches the changeset and the PR objectives, which describe a shared fake model upstream for CLI integration tests.

Full details: Docstring Coverage

Explanation

Docstring coverage is 12.50% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 8 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
