Iterate on PR Until CI Passes

Goal: fix actionable CI failures and high/medium review feedback. Stop and report human approval, draft-readiness, and merge-readiness gates.

Requires:

  • authenticated gh
  • uv
  • target repository root as cwd
  • skill-root-relative script paths, for example scripts/fetch_pr_checks.py

Bundled Scripts

| Script | Run | Output | |--------|-----|--------| | scripts/fetch_pr_checks.py | uv run scripts/fetch_pr_checks.py [--pr NUMBER] | JSON: pr, summary, checks, failure snippets | | scripts/fetch_pr_feedback.py | uv run scripts/fetch_pr_feedback.py [--pr NUMBER] | JSON buckets: high, medium, low, bot, resolved | | scripts/monitor_pr_checks.py | uv run scripts/monitor_pr_checks.py [--pr NUMBER] | terminal marker plus tab-separated checks | | scripts/reply_to_thread.py | uv run scripts/reply_to_thread.py THREAD_ID BODY [...] | JSON reply results |

Check summary fields include failed, pending, actionable_pending, and human_gate_pending.

Monitor markers:

  • ALL_CHECKS_PASSED
  • CHECKS_DONE_WITH_FAILURES
  • NO_CHECKS_REGISTERED
  • DRAFT_PR_WITH_NO_CHECKS
  • CHECKS_BLOCKED_BY_REVIEW_GATE

Workflow

1. Identify PR

Run:

gh pr view --json number,url,headRefName,isDraft,reviewDecision

Stop when:

  • no PR exists
  • draft PR has no checks after monitor grace period: report DRAFT_PR_WITH_NO_CHECKS

Draft rule: inspect existing checks/feedback only. Do not mark ready for review unless asked.

2. Handle Feedback

Run uv run scripts/fetch_pr_feedback.py [--pr NUMBER].

| Bucket | Action | |--------|--------| | high | fix | | medium | fix | | low | ask user which to address | | bot | skip informational comments | | resolved | skip |

Feedback fix checklist:

  • verify root cause
  • search related code
  • fix all instances
  • for review_bot: true: fix real issues, explain false positives

Low-priority prompt format:

Found 3 low-priority suggestions:
1. [l] "Consider renaming this variable" - @reviewer in api.py:42
2. [nit] "Could use a list comprehension" - @reviewer in utils.py:18
3. [style] "Add a docstring" - @reviewer in models.py:55

Which should I address? ("1,3", "all", or "none")

3. Check CI Status

Run uv run scripts/fetch_pr_checks.py [--pr NUMBER].

| State | Action | |-------|--------| | failed > 0 and actionable_pending == 0 | fix failures | | actionable_pending > 0 | wait; poll feedback while waiting | | pending > 0 and actionable_pending == 0 | report CHECKS_BLOCKED_BY_REVIEW_GATE | | no checks after grace period | report NO_CHECKS_REGISTERED or DRAFT_PR_WITH_NO_CHECKS | | all actionable checks passed | run post-CI feedback check |

Wait for actionable review bots: sentry, warden, cursor, bugbot, seer, codeql. Do not wait for approval, isDraft, REVIEW_REQUIRED, Codecov, or informational bots.

4. Fix CI Failures

For each failure:

  1. read full log: gh run view <run-id> --log-failed
  2. trace from assertion/exception/lint rule to source
  3. state the cause before editing: "fails because X, affected by Y"
  4. search related call sites/patterns
  5. fix root cause, not symptom
  6. add focused test coverage when needed

5. Verify Locally, Then Commit and Push

Before commit:

  • test fix: rerun specific test
  • lint/type fix: rerun affected checker
  • code fix: rerun covering tests
  • local failure: fix before pushing
git add <files>
git commit -m "fix: <descriptive message>"
git push

6. Monitor CI and Address Feedback

Loop:

  1. run uv run scripts/fetch_pr_checks.py
  2. handle table in step 3
  3. while actionable_pending > 0, run uv run scripts/fetch_pr_feedback.py
  4. fix new high/medium feedback immediately
  5. if changed, verify, commit, push, restart loop
  6. otherwise sleep 30 seconds and repeat
  7. after checks pass, wait 10 seconds, fetch feedback once more
  8. if new high/medium feedback exists, return to step 4

Claude Code optional: run uv run scripts/monitor_pr_checks.py through MonitorTool with persistent: false; set timeout to normal repo CI duration. Restart the monitor after every push.

Exit Conditions

| Exit | Conditions | |------|------------| | Success | actionable CI passed; post-CI feedback clean; low-priority choice handled | | Ask user | same failure after 2 attempts; feedback unclear; infrastructure issue | | Stop | no PR; branch needs rebase; no checks; draft no-checks; only human gates remain |

Fallback

If scripts fail, use gh CLI directly:

  • gh pr view --json number,url,headRefName,isDraft,reviewDecision
  • gh pr checks --json name,state,bucket,description,link
  • gh run view <run-id> --log-failed
  • gh api repos/{owner}/{repo}/pulls/{number}/comments
