Review Pr Comments

Review PR Comments

Fetch, summarize, and interactively triage review comments on the PR for the current git branch.

Prerequisites

• gh CLI authenticated with access to the repository
• Current branch must have an open PR (not main or a release branch like N.N.x)

Workflow

Step 1: Identify the PR

BRANCH=$(git branch --show-current)

Guard: skip if branch is main, master, or matches release pattern ^\d+\.\d+\.x$.

Find the PR:

gh pr list --head "$BRANCH" --json number,title,url,state --limit 5

If no PR found, inform the user and stop.

Step 2: Fetch all review data

Run these three gh api calls in parallel:

# Review comments (inline code comments)
gh api repos/{owner}/{repo}/pulls/{PR_NUMBER}/comments --paginate \
  --jq '.[] | {id, path, line, body, user: .user.login, created_at, in_reply_to_id, diff_hunk}'

# Top-level reviews (approval/request-changes status + body)
gh api repos/{owner}/{repo}/pulls/{PR_NUMBER}/reviews --paginate \
  --jq '.[] | {id, user: .user.login, state, body}'

# Issue-level comments (general PR discussion, CI bot reports)
gh api repos/{owner}/{repo}/issues/{PR_NUMBER}/comments --paginate \
  --jq '.[] | {id, user: .user.login, body, created_at}'

Extract {owner} and {repo} from gh repo view --json owner,name.

Step 3: Organize into threads

Group review comments into conversation threads using in_reply_to_id:

• A comment with in_reply_to_id: null starts a new thread
• Replies link to their parent thread

For each thread, track:

• File & line from the root comment
• Author of the root comment
• All replies in chronological order
• Resolution status: resolved if the PR author replied last

Step 4: Classify comments

Separate into two groups:

Bot comments (user login ends with [bot] or is a known CI bot):

• Summarize briefly (e.g., "CI quality gates passed", "Regression detector: no regressions")
• Only highlight actionable items (failures, warnings)

Human reviewer comments:

• These get full treatment in Step 5

Step 5: Present and triage each human comment

For each unresolved human reviewer comment thread:

• Show context: file, line, diff hunk, the comment body
• Read the current file at the referenced location to understand current state
• Summarize the reviewer's concern in one sentence
• Propose a concrete action: code fix, reply text, or explanation
• Ask the user what to do using AskQuestion:

Options:
- "Fix" → Apply the proposed code change
- "Reply" → Post a reply comment on the PR via gh api
- "Reply with custom message" → Ask user for reply text, then post
- "Add TODO" → Add a TODO item to track for later
- "Skip" → Move to next comment

For already-resolved threads (PR author replied last), present them as a summary group:

• Show the comment + your reply, note it's resolved
• Ask if user wants to revisit any

Step 6: Execute chosen actions

Fix: Edit the file, show the diff to the user. Do NOT commit automatically.

Reply: Post via gh API:

gh api repos/{owner}/{repo}/pulls/{PR_NUMBER}/comments \
  -f body="$REPLY_TEXT" -f in_reply_to=$COMMENT_ID

TODO: Use the TodoWrite tool to track it.

Step 7: Summary

After processing all comments, output a summary table:

| # | File | Reviewer | Action Taken |
|---|------|----------|--------------|
| 1 | path/to/file.go:42 | reviewer1 | Fixed |
| 2 | path/to/other.py:10 | reviewer2 | Replied |
| 3 | path/to/build.bzl:5 | reviewer3 | Skipped (already resolved) |

Edge Cases

• No unresolved comments: Report "All review comments are resolved" with approval status summary
• PR not found: Suggest the user push the branch or create a PR first
• Outdated diff hunks: Note that the comment may reference old code; read the current file to verify
• Multiple PRs for branch: Use the most recent open one
