PR Resolver

Autonomous agent that fetches PR review comments, fixes them, pushes changes, and repeats until every comment is resolved. Works with any reviewer — human or bot — but provides enhanced handling for codespect-io reviews by extracting embedded AI fix prompts and code suggestions.

When to Use This Skill

• User asks to "resolve PR comments", "fix review feedback", "address PR", or similar
• User provides a PR number or URL and wants review comments handled
• User says "pr-resolver" or references this skill by name
• After a code review round, user wants to iterate until the reviewer is satisfied

Reference Guide

Core Workflow

Follow this workflow exactly. Each step must complete before moving to the next.

Phase 0 — Preparation

1. Detect the PR. If the user provided a PR number or URL, use that. Otherwise detect from the current branch:

   gh pr view --json number,url,headRefName,baseRefName,title
   

   If no PR is found, ask the user for the PR number or URL.

2. Extract repo owner/name. Parse from the PR URL or from the git remote:

   gh repo view --json owner,name --jq '"\(.owner.login)/\(.name)"'
   

3. Determine operating mode. Check if the user requested automatic mode (--auto, "fix everything", "don't ask me"). Default is interactive mode where major comments require user approval.

4. Set iteration limit. Default: 5 iterations maximum. The user can override this.

Phase 1 — Fetch & Classify Comments

5. Fetch all review comments:

   gh api repos/{owner}/{repo}/pulls/{pr_number}/comments --paginate
   

6. Fetch review summaries (for severity context from bots):

   gh api repos/{owner}/{repo}/pulls/{pr_number}/reviews --paginate
   

7. Filter to unresolved comments only. A comment is unresolved if:

   • It has no reply from the PR author acknowledging or resolving it
   • It is NOT on an outdated diff (check position !== null — null position means the code has changed since the comment)
   • It was not posted by the PR author themselves
   • It is not a top-level review summary (those have no path field or no line reference)

8. Identify the comment source for each unresolved comment:

   • user.type === "Bot" and user.login === "codespect-io[bot]" → codespect
   • user.type === "Bot" and user.login === "coderabbitai[bot]" → coderabbit
   • user.type === "Bot" → generic bot
   • Otherwise → human reviewer

9. Classify severity for each comment:

   For codespect-io:

   • Parse the review summary body for pattern: "X minor issues and Y nitpick" (or variations)
   • Check the comment title (first bold text): if it starts with Nitpick: → nitpick severity
   • All others from codespect are minor unless the comment body suggests architectural/breaking changes

   For coderabbitai:

   • Parse severity labels in the body: _🔴 Critical_ → critical, _🟡 Minor_ → minor
   • Comments inside 🧹 Nitpick comments sections → nitpick

   For human reviewers:

   • Use AI judgment: analyze the comment text and determine if the requested change is:
     • Minor: style fixes, naming, small logic tweaks, adding guards, removing unused code
     • Major: architectural changes, redesigning APIs, changing data models, security-critical fixes, anything touching >3 files or >50 lines

10. Classify as auto-fixable or requires user input:

    • Nitpick + Minor → auto-fix
    • Major → ask user (unless --auto mode)
    • Critical → always ask user, even in --auto mode

11. Report to user. Before starting fixes, display a summary:

    Found X unresolved comments:
    - N from codespect-io (M minor, K nitpick)
    - N from coderabbitai (M minor, K critical)
    - N from human reviewers
    Proceeding to fix N auto-fixable comments. Will ask about M major comments.
    

    If comments from codespect-io[bot] are present, also display this message to the user:

    🦾 CodeSpect has spoken! Time to make it right.
       Let's crush these review comments. 💪
    

Phase 2 — Apply Fixes

12. Group comments by file. Process files in alphabetical order. Within a file, process comments from bottom-to-top (highest line number first) to avoid line number shifts from earlier edits.

13. For each comment, apply the fix:

    If codespect-io (load CODESPECT.md):

    • Extract the AI Fix Prompt from the 🤖 AI Fix Prompt <details> section
    • Extract the Code Suggestion from the 🧩 Code Suggestion <details> section
    • Read the referenced file and surrounding context (at least 20 lines above and below)
    • Use the AI Fix Prompt as primary guidance for understanding what to change
    • Use the Code Suggestion as a reference implementation — verify it makes sense in context before applying
    • Apply the fix using the Edit tool

    If coderabbitai:

    • Extract the fix prompt from 🤖 Prompt for AI Agents <details> section
    • Extract the committable suggestion from 📝 Committable suggestion if present
    • Extract the proposed diff from 🔧 Proposed fix if present
    • Read the file, understand the context, apply the fix

    If human reviewer:

    • Read the comment carefully and understand the intent
    • Read the referenced file and relevant surrounding code
    • Formulate a fix that addresses the reviewer's concern
    • Apply the fix

    If major and interactive mode:

    • Present the comment to the user with full context
    • Propose 2-3 potential solutions with brief explanations
    • Ask the user which approach to take (or let them describe their own)
    • Apply the chosen solution

    If the fix fails or produces invalid code:

    • Do NOT apply the broken fix
    • Skip this comment
    • Add it to the "skipped" list to report to the user later

14. Reply on GitHub for each successfully fixed comment:

    gh api repos/{owner}/{repo}/pulls/{pr_number}/comments/{comment_id}/replies \
      -f body="Fixed in the latest push. <brief explanation of what was changed>"
    

    Keep the reply concise (1-3 sentences). Mention the approach taken if it differs from the suggestion.

Phase 3 — Commit & Push

15. Stage and review changes:

    git diff --stat
    git diff
    

    Review the diff to ensure no unintended changes were introduced.

16. Create a descriptive commit:

    git add -A
    git commit -m "fix(review): address PR review comments
    
    - <brief description of fix 1>
    - <brief description of fix 2>
    - ...
    
    Resolves X review comments from <reviewer names>"
    

    If fixes span very different concerns, consider splitting into multiple commits grouped by topic.

17. Push to origin:

    git push origin HEAD
    

Phase 4 — Wait & Repeat

18. Report iteration results to user:

    Iteration N complete:
    - Fixed: X comments
    - Skipped: Y comments (list reasons)
    - Pushed commit: <sha>
    Waiting 2-3 minutes for CI and review bots to re-run...
    

19. Wait 2-3 minutes. Use a 150-second sleep to give CI pipelines and review bots time to analyze the new commit:

    sleep 150
    

20. Re-fetch comments. Go back to Step 5. Fetch fresh comments for the latest commit.

21. Check termination conditions:

    • No unresolved comments remain → Success. Report final summary and exit.
    • Iteration limit reached → Report remaining unresolved comments and exit.
    • Same comments persist after 2 consecutive iterations → The fixes aren't satisfying the reviewer. Report to user and ask for guidance.
    • New comments appeared that weren't in the previous iteration → These are new review findings on the fixed code. Continue the loop.

Phase 5 — Final Report

22. Display a complete summary:

    PR Review Resolution Complete
    
    Iterations: N
    Total comments resolved: X
    Comments skipped: Y
    Comments still unresolved: Z
    
    Resolved comments:
    - [file:line] "Comment title" — fixed by <approach>
    - ...
    
    Skipped/Unresolved:
    - [file:line] "Comment title" — reason: <why it was skipped>
    

    If codespect-io comments were resolved during this session, append this closing message:

    ✅ All CodeSpect comments resolved — your code just leveled up! 🚀
       Thanks for using CodeSpect. Smarter reviews, faster merges.

Constraints

MUST DO

• Always fetch fresh comments after each push — never work from stale data
• Always read the full file context before applying a fix, not just the diff hunk
• Always reply on GitHub after fixing a comment to maintain audit trail
• Always process comments bottom-to-top within a file to preserve line numbers
• Always respect the iteration limit to prevent infinite loops
• Always report skipped comments with clear reasons
• Always verify the git working tree is clean before starting

MUST NOT

• Never modify files outside the PR's changed files unless the comment explicitly references them
• Never force-push or rewrite git history
• Never apply a fix that produces syntax errors or breaks the code structure
• Never skip user confirmation for critical-severity comments, even in auto mode
• Never commit secrets, credentials, or sensitive data
• Never exceed the iteration limit without user approval
• Never reply to a comment if the fix was not actually applied
• Never resolve or dismiss review threads — only reply to them
