name: fix-bug-pr description: Find bug-type PRs with unresolved bug items (Issues Found table), fix and push updates, comment with what changed, and keep PR body status synced (set to fixed when complete).

Fix Bug PR

Contract

Prereqs:

• Run inside the target git repo.
• git and gh available on PATH, and gh auth status succeeds.
• python3 available on PATH (helper scripts parse/patch PR Markdown deterministically).
• Start from a clean working tree (avoid staging unrelated local changes).

Inputs:

• Optional PR number to operate on; otherwise resolve an open bug-type PR automatically.
• Optional label filters to narrow candidate PRs (defaults: bug, type: bug).

Outputs:

• If a matching PR exists:
  • Code fix committed and pushed to the PR head branch.
  • PR comment describing what changed, tests run, and which bug IDs were updated.
  • PR body updated so the Issues Found table reflects latest bug Status; if all bugs are fixed, set overall Status: fixed.
• If no bug-type PR exists (or none with unresolved bugs): no repo changes; report “no related issues”.

Exit codes:

• N/A (workflow skill). Helper scripts define their own exit codes.

Failure modes:

• No matching bug-type PR found, or PR body does not include a parseable ## Issues Found table.
• Missing tooling (gh/git/python3) or gh not authenticated.
• Dirty working tree, merge conflicts, or failing tests prevent a safe commit/push.
• High-risk areas (auth/billing/migrations/deploy) should stop or be skipped.

Workflow

1. Resolve the target PR:

   • Auto-pick an open PR with unresolved bug items:
     • $CODEX_HOME/skills/automation/fix-bug-pr/scripts/bug-pr-resolve.sh
   • Or target a specific PR:
     • $CODEX_HOME/skills/automation/fix-bug-pr/scripts/bug-pr-resolve.sh --pr <number>
   • If it exits 2: stop and report “No relevant issues found (no bug-type PR found).”

2. Checkout the PR branch:

   • gh pr checkout <number>

3. Identify the next unresolved bug item:

   • Use next_bug_id from bug-pr-resolve.sh output.
   • Fix one bug item per run unless multiple items share the same root cause.

4. Implement the minimal fix + validation:

   • Prefer small, targeted diffs; avoid refactors.
   • Follow the target repo’s testing/build docs and CI workflow: install required tooling/deps, then run the most relevant lint/test/build commands.
   • If docs are missing/unclear, infer likely commands from common entrypoints (package.json scripts, Makefile/Justfile/Taskfile, language defaults).
   • Treat validation as a gate: if checks fail, do not commit/push; fix and re-run (or stop and report). If checks cannot be run, document why in the PR comment.

5. Commit + push:

   • Use semantic-commit-autostage (end-to-end automation) unless the user explicitly wants manual staging.
   • Push to the PR head branch.

6. Update PR body progress (status sync):

   • Mark the fixed bug ID(s) as fixed and recompute overall status:
     • $CODEX_HOME/skills/automation/fix-bug-pr/scripts/bug-pr-patch.sh --pr <number> --mark-fixed <bug_id>
   • If all bug items are fixed, the PR body will be updated to Status: fixed.

7. Comment on the PR with what changed:

   • Include: fixed bug IDs, summary, tests run, and any remaining open items.
   • Use skills/automation/fix-bug-pr/references/COMMENT_TEMPLATE.md as the structure.
