Iterate Pr

Iterate PR

Autonomously iterate on a pull request until CI checks pass and all comments are resolved. Each iteration runs in a fresh subagent.

Arguments

• $ARGUMENTS - Maximum iterations (default: 3)

Instructions

Step 1: Initialize

Parse max iterations from $ARGUMENTS (default: 3). Set iteration counter to 0.

Step 2: Check State

Get the PR for the current branch:

!gh pr view --json number,url,headRefName,statusCheckRollup 2>/dev/null || echo "NO_PR"

If no PR exists: Proceed to Step 3 (first iteration will create one).

If PR exists: Get unresolved comments data:

!bash "${CLAUDE_PLUGIN_ROOT:-.agents}/skills/unresolved-pr-comments/scripts/unresolvedPrComments.sh" 2>/dev/null

Parse the JSON output and evaluate exit conditions.

If any CI checks are still PENDING, QUEUED, or IN_PROGRESS: Proceed to Step 3 regardless of comment count. Automated reviewers (e.g. CodeRabbit) may not have posted comments yet, so comment data is unreliable until all checks complete.

If statusCheckRollup is empty or null: Treat CI as passing (some PRs have no required checks configured).

Exit with success when ALL conditions are met:

• All CI checks have completed (no PENDING, QUEUED, or IN_PROGRESS statuses in statusCheckRollup) and none have failed (or no checks exist)
• No unresolved comments (totalUnresolvedComments == 0)
• No nitpicks (totalNitpicks == 0)

JSON Structure for Exit Evaluation:

{
  "totalUnresolvedComments": number,
  "totalNitpicks": number,
  "unresolvedComments": [...],
  "nitpickComments": [...]
}

Check totalUnresolvedComments == 0 and totalNitpicks == 0 for exit condition.

Report: "PR is clean! All CI checks pass and no unresolved comments."

Exit with status report when iteration counter >= max iterations:

• List failing CI checks
• List unresolved comment/nitpick counts
• Suggest running /iterate-pr again to continue

Step 3: Spawn Iteration Subagent

Spawn a Task subagent with subagent_type: "general-purpose" using this prompt:

Handle one iteration of the PR feedback loop:

1. Record Starting Commit: !git rev-parse HEAD (save as startCommit)
2. Commit and Push: Invoke core:commit-push-pr via the Skill tool
3. Get PR Number: !gh pr view --json number --jq '.number'
4. Wait for CI: !rc=0; if command -v gtimeout >/dev/null 2>&1; then gtimeout 600 gh pr checks --watch || rc=$?; elif command -v timeout >/dev/null 2>&1; then timeout 600 gh pr checks --watch || rc=$?; else gh pr checks --watch || rc=$?; fi; case $rc in 0|1|8|124) ;; *) exit $rc;; esac (10 minute timeout; exit codes: 0=pass, 1=fail, 8=pending, 124=timeout are expected and handled in next step; other codes like 4=auth error are re-raised; uses gtimeout on macOS, timeout on Linux, no timeout as fallback)
5. Check CI Status: Run gh pr checks --json name,state,bucket and parse the output
   • If any check has bucket: "fail", invoke core:fix-ci via the Skill tool. Since you are running autonomously, do NOT wait for user approval — apply the fixes directly. Report what was fixed and exit.
6. Check Comments: Run bash "${CLAUDE_PLUGIN_ROOT:-.agents}/skills/unresolved-pr-comments/scripts/unresolvedPrComments.sh" and parse the JSON output
   • If unresolved comments or nitpicks exist:
     1. Group comments by file path and read each file once (not per-comment)
     2. If a file no longer exists, note the comment may be outdated and skip it
     3. Assess each comment with an explicit verdict:
        • Agree: Explain why, then fix it
        • Disagree: Explain why the current code is acceptable; do NOT change the code
        • Already fixed: Note that the code already addresses this concern
     4. After assessing all comments, fix only those you agreed with and exit (next iteration will commit fixes)
7. Report: Run git rev-parse HEAD and compare to startCommit to determine if commits were made. Include PR status, CI status, and comments addressed

Step 4: Loop

After the subagent completes:

1. Increment iteration counter
2. If no commits were made this iteration:
   • Get unresolved comments by running: bash "${CLAUDE_PLUGIN_ROOT:-.agents}/skills/unresolved-pr-comments/scripts/unresolvedPrComments.sh"
   • If unresolved comments remain, exit with: "Comments addressed, awaiting reviewer resolution. Run /iterate-pr after reviewer responds."
3. Report: "Iteration [N]/[max] complete. Checking state..."
4. Return to Step 2

Examples

Successful completion:

Iteration 1/3: No PR exists
> commit-push-pr -> PR #347 created
> CI failed (lint errors) -> fix-ci -> fixed missing semicolons

Iteration 2/3: CI failures remain
> commit-push-pr -> pushed fixes
> CI passed, 2 review comments
> unresolved-pr-comments -> addressed null check, const usage

Iteration 3/3: Comments pending
> commit-push-pr -> pushed fixes
> CI passed, no unresolved comments

PR is clean! All CI checks pass and no unresolved comments.

Awaiting reviewer resolution:

Iteration 1/3: PR exists with comments
> commit-push-pr -> pushed comment fixes
> CI passed, 1 comment remains (disagreed with suggestion)

Iteration 2/3: No commits made, comments remain

Comments addressed, awaiting reviewer resolution. Run `/iterate-pr` after reviewer responds.
