Context

New eligible community issues receive an automated comment and labels by default. The comment follows the Mastra handoff format: a summary table, source findings, assumptions, open questions, and reproduction notes. Publication does not require maintainer approval.

Changes & Results

  • Automatic runs default to live. Set ISSUE_TRIAGE_MODE to dry-run for summaries only or off to stop automatic runs.
  • Users with repository write access can run the workflow manually on main. Manual runs post by default. Clear post_comment to analyze without posting comments or labels.
  • The analyze job uses the issue-triage environment. Its branch policy permits only main, with no required reviewers. Store the Claude OAuth token only in that environment.
  • The GitHub token used for analysis has read-only permissions. A Bash hook checks command arguments and disables external Git diff programs. Python runs in isolated mode. Unexpected validation errors deny the command. A launch failure or the inner timeout returns blocking exit code 2 before the Claude hook timeout expires.
  • The prompt is covered by CODEOWNERS. It checks the current package and viewport files and includes existing Karma, Jest, Vitest browser, and unit-test locations.
  • Classification describes the issue type. A bug that needs reporter information keeps type:bug and uses status:ask-reporter. A fixed mapping keeps the comment's route display consistent with structured output.
  • The publish job has issue-write permission and does not run Claude. A separate concurrency group permits one publisher per issue. Reruns update the marked comment and replace earlier managed labels.
  • Each issue receives one managed type: label and one managed status: label. Area, severity, confidence, effort, and impact appear in the comment table. Other labels stay in place. Spam receives no comment or labels.
  • The job summary reports numeric token counts, turns, duration, and the SDK cost estimate when available. It does not publish the execution transcript. The SDK cost estimate does not measure OAuth plan quota. Opus and the 80-turn limit remain unchanged.

Configuration

Setting Value
Environment issue-triage; branch main only; no required reviewers
Environment secret CLAUDE_CODE_OAUTH_TOKEN Required: output of claude setup-token; remove the repository secret copy after saving it here
vars.ISSUE_TRIAGE_MODE Unset or live: comment and labels; dry-run: summary only; off: no automatic runs
vars.ISSUE_TRIAGE_MODEL Optional; defaults to opus

The environment and its branch policy are configured. The environment secret must be saved and the repository copy removed before merge. GitHub cannot return the existing secret value for migration.

Automatic runs cover non-bot issue authors with associations NONE, CONTRIBUTOR, FIRST_TIME_CONTRIBUTOR, or FIRST_TIMER. Reporter replies do not start another run. Community reporters do not receive label permissions.

Testing

  • actionlint v1.7.12 passes. All four embedded Bash blocks pass syntax checks. Python, JSON schema, and hook settings parse.
  • Prettier v3.6.2 checks pass for the changed Markdown and YAML files. git diff --check passes.
  • Local hook checks permit a Git read query, deny the unused template option, and deny a simulated unexpected validator error. The launcher returns exit code 2 when its runtime utility is unavailable.
  • Local label checks retain a bug's type, select the reporter-information status, replace earlier managed labels, and preserve other labels.
  • Usage formatting reads only numeric fields from sample SDK results and excludes transcript text.
  • Full Claude/Actions execution and the GNU timeout deadline on Ubuntu remain unverified. The workflow must be on the default branch before dispatch. Actual quota use will be assessed from real runs.

Checklist

PR

  • The title follows the semantic-release format.

Code

  • The workflow, prompt, and command check include purpose documentation.

Public Documentation Updates

  • No public API changes require documentation updates.

Tested Environment

  • OS: macOS for local checks. Ubuntu runner execution remains unverified.
  • Node version: 22.23.1 for formatting only.
  • Browser: not applicable.

Summary by CodeRabbit

  • New Features
    • Newly opened eligible issues can receive automated first-pass triage, and manual triage is available for a specified issue.
    • Triage results include a structured assessment, affected areas, severity, confidence, and open questions.
    • Results appear in the workflow summary; they can also be published as an issue comment, with supported triage labels applied.
    • Spam is excluded from comments and label changes.
    • Automatic comment publishing is limited to live mode; dry-run mode reports results without publishing them.

New community issues get one structured triage comment (type, area,
regression, route, severity, confidence, effort, next step, then the
investigation). The prompt lives in .agents/skills/issue-triage.md.

The analyze job runs Claude Code read-only and returns the comment as
structured output; the publish job posts it and adds labels from a fixed
list. Automatic runs stay off until ISSUE_TRIAGE_MODE is set to dry-run
or live; any issue can be triaged by hand from the Actions tab.

📝 Walkthrough

Walkthrough

Adds an issue-triage skill for read-only issue investigation and structured handoff. Adds command validation for permitted Git and GitHub CLI queries. Adds a workflow that analyzes qualifying or manually selected issues and conditionally publishes comments and labels.

Changes

Issue Triage

Layer / File(s) Summary
Investigation guidance and handoff format
.agents/skills/issue-triage.md, .github/CODEOWNERS
Defines read-only investigation rules, issue assessment fields, managed labels, and the structured handoff comment. Adds an owner rule for the skill.
Read-only command validation
.github/scripts/issue-triage-command-check.py
Defines allowlists for Git and GitHub CLI commands and options. Rejects shell syntax and invalid arguments, normalizes accepted commands, and returns an allow or deny response.
Workflow triggers and analysis
.github/workflows/issue-triage.yml
Adds issue-opened and manual-dispatch triggers, eligibility conditions, and a read-only Claude analysis job with structured output and job-summary reporting.
Comment and label publishing
.github/workflows/issue-triage.yml
Adds conditional publication of non-spam results. Updates managed labels and creates or edits marked comments, truncating comment bodies over 60,000 characters.

Claude Code Review

Claude Code Review is paused for this repository. To reconnect it, an admin of this repository's GitHub organization (or the account owner, for personal repositories) who can also manage your Claude organization's Code Review settings needs to re-link GitHub in Code Review settings. This is a one-time step.

Tip: disable this comment in your organization's Code Review settings.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep automatic triage off until a mode is set.

When ISSUE_TRIAGE_MODE is unset, GitHub Actions returns an empty string. Both || 'live' expressions then enable analysis and publication for eligible new issues. This bypasses the stated manual and dry-run rollout and can post public comments before live mode is enabled. Require an explicit dry-run or live value in analyze, and an explicit live value in publish. Update the setting description to match. (docs.github.com)

Also applies to: 132-132
