description	Iterate on a PR until actionable CI passes and high/medium review feedback is addressed. Use for PR CI failures, review feedback, or green-check loops; do not wait for human approval, draft status, or merge gates.

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
