It invokes +[issue-triage.agent.md](.github/agents/issue-triage.agent.md) with Copilot CLI to +inspect the triggering default-branch commit and relevant tests, then posts an +AI-disclosed comment with findings, source links, questions, and next steps. +GitHub delivers the issue event directly to Actions; no external webhook +endpoint is needed. Edits, comments, reopened issues, and bot-authored issues +do not trigger runs. + +### Enable triage + +1. Create a fine-grained personal access token for a Copilot-enabled account + with the **Copilot Requests** permission. Store it as the Actions repository + secret **COPILOT_GITHUB_TOKEN** under **Settings > Secrets and variables > + Actions**. Do not put the token in an issue, source file, or agent prompt. + The token does not need repository write permissions. Your account and + organization policies must permit Copilot CLI use. +2. Ensure Actions policies allow `contents: read` and `issues: write`. The + workflow uses the built-in `GITHUB_TOKEN` only for checkout and the separate + comment-publishing step, not for model tools. +3. Merge the agent, workflow, and runner into the default branch. Open a new + issue with a sanitized report and inspect **Actions > Issue Triage** and + the resulting issue comment. Existing issues are not backfilled. + +The model can read and search local source, but cannot execute commands, edit +files, or use GitHub/MCP tools. Investigation is static: it does not run tests +or reproduce the report. The runner passes issue text as JSON data, not shell +code. It validates the draft before publishing, skips closed issues, and +updates its marked `github-actions[bot]` comment on reruns instead of posting +duplicates. It never labels, assigns, closes issues, or creates pull requests. +These are maintainer automation permissions, not a change to CompareLab's +interactive read-only tool policy. + +Every qualifying issue can consume the token owner's Copilot allowance and +Actions minutes, including reports from outside contributors. The workflow has +a 15-minute timeout and the model invocation an 8-minute timeout; these are not +spending caps. Monitor usage, or disable **Issue Triage** in Actions to stop new +runs. Prompt-injection instructions and tool restrictions reduce risk but do +not guarantee factual accuracy or prevent inappropriate generated text; review +public comments, particularly reports involving security or sensitive data. + +If authentication, generation, draft validation, or GitHub publication fails, +the run fails without posting a fallback diagnosis. Correct the configuration +and rerun the original run; reruns use that run's original code and issue +snapshot. A code fix requires a new issue event after the fix is merged. +The CLI is pinned in the workflow; review and validate version upgrades. + +Run `node --test test/issue-triage.test.js` for mocked event, tool-boundary, +failure, pagination, and rerun checks. `npm run build` includes those tests but +does not validate live Copilot authentication, investigation quality, or GitHub +comment permissions. + ## Icons and sidebar [media/comparelab.svg](media/comparelab.svg) is the artwork source and Activity Bar icon.
