Review PR feedback

Address PR Review Comments

Automates addressing pull request review feedback: analyze comments, make fixes, reply to explain changes, resolve threads, and request re-review from @codex.

Prerequisites

• Must have gh CLI authenticated
• Must be in a git repository with a GitHub remote

Step 1: Validate Input

If $ARGUMENTS is empty:

• Use AskUserQuestion to ask for the PR number
• Validate it's a number

If $ARGUMENTS is provided:

• Extract PR number from $ARGUMENTS
• Validate it's a valid number

Step 2: Fetch PR Review Threads

Run this GraphQL query to get all unresolved review threads:

gh api graphql -f query='
query {
  repository(owner: "{owner}", name: "{repo}") {
    pullRequest(number: PR_NUMBER) {
      id
      reviewThreads(first: 100) {
        nodes {
          id
          isResolved
          path
          line
          comments(first: 10) {
            nodes {
              id
              databaseId
              body
              author {
                login
              }
            }
          }
        }
      }
    }
  }
}'

Filter to only unresolved threads (isResolved: false).

If there are no unresolved threads, inform the user and exit.

Step 3: Analyze and Categorize Comments

For each unresolved thread:

1. Read the comment body to understand the feedback
2. Identify the file path and line number
3. Read the relevant file section to understand the context
4. Categorize the type of feedback:
   • Code change needed - requires file modification
   • Documentation - needs comment/doc update
   • Question - requires explanation only, no code change
   • Disagree/Won't fix - ASK USER before responding

Present a summary to the user showing:

• Number of comments found
• File paths affected
• Brief description of each comment

IMPORTANT: For any comment where you disagree or think "won't fix" is appropriate, use AskUserQuestion to get user confirmation before replying. Never auto-resolve disagreements.

Step 4: Address Each Comment

For each comment requiring action:

4a. Read the relevant file

Use the Read tool to understand the context around the specified line.

4b. Make the fix

Use the Edit tool to make the necessary changes based on the feedback.

4c. Reply to the comment

Use REST API to reply to the comment explaining what was done:

gh api --method POST \
  repos/{owner}/{repo}/pulls/PR_NUMBER/comments/COMMENT_DB_ID/replies \
  -f body='Fixed: [explanation of what was changed and why]'

Keep replies concise but informative. Explain WHAT was changed and WHY.

4d. Resolve the thread

Use GraphQL mutation to resolve the thread:

gh api graphql -f query='
mutation {
  resolveReviewThread(input: {threadId: "THREAD_NODE_ID"}) {
    thread { isResolved }
  }
}'

Step 5: Commit Changes

After all fixes are made:

1. Stage all changed files with git add
2. Create a commit with a descriptive message following conventional commits format:

git commit -m "fix: address PR review feedback

- [list each fix made]
- [reference comment IDs if helpful]

🤖 Generated with [Codex]

3. Push the changes to the remote branch

Step 6: Request Re-Review

Add a comment to the PR requesting re-review from @codex:

gh pr comment PR_NUMBER --body '@codex review'

Step 7: Summary

Present a summary to the user:

• Number of comments addressed
• Files modified
• Commit hash created
• Any comments that were NOT addressed (with reasons)
• Link to the PR

Error Handling

• If gh CLI is not authenticated, instruct user to run gh auth login
• If PR number is invalid, show error and ask for correct number
• If a thread fails to resolve, log the error but continue with other threads
• If commit fails, show the error and suggest manual resolution
