Documentation

TurnSignal for Playwright

Source of the turnsignal npm package: the Playwright reporter, the turnsignal CLI and the TurnSignal MCP server for coding agents. MIT licensed.

TurnSignal keeps every Playwright test's results across CI runs and branches, and labels each failure as a new failure, also failing on main or known flaky. Package docs: packages/turnsignal/README.md.

MCP server

Read-only Playwright CI results for coding agents (Claude Code, Cursor, Copilot, ...). Before an agent "fixes" a failing test, it can check whether the failure is new in this pull request, already failing on main, or known flaky.

Tool	What it returns
`turnsignal_recent_runs`	Recent CI runs: verdict, status, branch, commit, counts, run id
`turnsignal_run`	One run's results: new failures, already failing, flaky, missing tests, with errors
`turnsignal_test_history`	One test's recent outcomes across runs
`turnsignal_flaky_tests`	Tests that were flaky in the last N days, most flaky first

    }
  }
}

Claude Code: claude mcp add turnsignal -e TURNSIGNAL_TOKEN=<token> -- npx -y turnsignal mcp

The server talks JSON-RPC over stdio and only reads data the project token can see. It is listed in the official MCP Registry as ai.turnsignal/turnsignal.

Layout

Path	What
`packages/shared`	Wire format, test identity, secret redaction
`packages/playwright-reporter`	The Playwright reporter (crash-safe local copy, never changes your exit code)
`packages/cli`	`turnsignal upload`, `comment`, `governance`, `doctor`, `mcp` (src/mcp.ts)
`packages/turnsignal`	The published package: an esbuild bundle of the three above

npm test            # build + unit tests
npm run package     # builds packages/turnsignal/dist

The hosted service (API and web app) is not part of this repository; ADR-NNN references in code comments point to its internal design records.
