PR Comments Address

Read open review comments from a GitHub PR, intelligently triage them by severity and type, apply code fixes, and draft professional replies. This skill ensures no feedback is missed and all changes are intentional.

Workflow

Phase 1: Detect PR and Fetch Comments

Identify the PR from arguments or auto-detect from current branch:

# If PR number/URL provided as argument, use it
# Otherwise detect from current branch
gh pr view --json number,url,title,body,author

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

Fetch all review comments from the PR:

gh pr view <PR> --json reviews,comments,reviewThreads

Parse the JSON output to extract:

• Comment author and timestamp
• File and line number
• Comment body
• Whether the comment thread is resolved
• Whether the comment is a review or standalone comment

Read any project-specific rules from CLAUDE.md or .claude/rules/ if they exist (e.g., code style, testing requirements, review conventions). Apply those rules when triaging comments.

Phase 2: Triage Comments by Category

Categorize every unresolved comment into exactly one category:

Category	Definition	Action	Example
Must-fix	Required change, unambiguous, blocking merge	Apply code change	"Add error handling for null case"
Should-fix	Recommended improvement, clear intent, improves quality	Apply code change after confirmation	"Extract this to a separate function for readability"
Clarification needed	The intent is unclear or the solution depends on context	Ask user for decision	"Why does this use setTimeout instead of Promise?"
Discussion / Question	No code change needed, just needs a reply	Draft reply only	"What's the performance impact of this change?"
Praise / Acknowledgement	Positive feedback or agreement	Brief acknowledgement	"Nice implementation!"

Triage decision tree:

1. Is the change clearly defined? → Must-fix or Should-fix
2. Is there any ambiguity about the solution? → Clarification needed
3. Does it require a code change? → Must-fix or Should-fix; if no: Discussion/Question
4. Is it subjective feedback? → Discussion/Question

Output a triage table showing every comment, its category, and the required action.

Phase 3: Resolve Ambiguities

Present all "clarification needed" comments to the user with full context (file, line number, comment text). For each one, explicitly ask: "What should be changed?"

Do not proceed until the user has answered every ambiguous comment.

Phase 4: Present the Change Plan

Show the full plan for every code change:

For must-fix and should-fix comments:

• File path and line numbers
• Current code (1-2 lines context)
• Proposed change
• Rationale (from the comment or context)

For discussion/question comments:

• The question or feedback
• Proposed reply

Ask the user: "Should I proceed with these changes?"

Wait for explicit user confirmation before making any edits.

Phase 5: Apply Code Fixes

For each approved code change:

1. Read the full file first — never patch blindly from the comment
2. Make the minimal change that addresses the comment — no scope creep
3. Keep edits independent — apply changes one at a time to avoid conflicts
4. Do not refactor or reformat outside the scope of the comment
5. Verify the change is applied by reading the relevant lines after the edit

Example workflow for a single change:

cat src/auth.ts          # read file
                         # make the change (using Edit tool)
git diff src/auth.ts     # then verify

Phase 6: Verify Changes

After all code changes are applied, verify:

1. File syntax is valid (no broken imports, missing brackets, etc.)
2. Changes align with the comment intent
3. No unintended side effects (test imports, unused variables, etc.)

Use git diff to review all changes at once:

git diff

Phase 7: Draft Replies

For every comment (must-fix, should-fix, clarification, discussion, praise), draft a reply:

For applied changes (must-fix, should-fix):

• Confirm what was changed, factually and briefly
• Example: "Done — extracted into a separate function validateUser() in auth.ts:45-60."

For clarifications now resolved:

• Brief explanation of the decision
• Example: "Using setTimeout here to avoid race conditions with pending state updates."

For questions/discussion:

• Answer directly without over-explaining
• Keep it professional and concise
• Example: "Good catch — I'll verify the performance impact in the staging environment."

For praise/acknowledgements:

• Brief, genuine acknowledgement
• Example: "Thanks for the review!"

Important: Do not use filler phrases like "Great point!", "Thanks for catching that!", "Absolutely!", "Looking forward to your feedback!" These add noise without substance.

Phase 8: Present Reply Drafts

Show all draft replies to the user for review. Ask: "Should I post these replies?"

Wait for user approval before posting anything.

Phase 9: Post Replies

Once approved, post each reply to its corresponding comment thread:

gh pr comment <PR> --in-reply-to <COMMENT_ID> --body "<reply text>"

Or use the GitHub API directly if the command-line interface differs:

gh api repos/{owner}/{repo}/pulls/comments/{comment_id}/replies \
  -f body="<reply text>"

Confirm which replies were posted successfully.

Important Principles

• Never guess ambiguity resolution — always ask the user explicitly
• Confirm changes factually — "Done — added null check at line 42" not "Fixed the issue"
• One file at a time — apply changes sequentially to avoid merge conflicts
• No scope creep — fix the comment, nothing more
• Professional tone — direct, factual, no corporate pleasantries
• Do not resolve threads — let the reviewer do that after they read your replies
• Do not push or open PRs — only apply code and draft replies

Examples

Positive Trigger

User: "address the review comments and fix the code feedback on PR #42"

Expected behavior: Fetch comments from PR #42, triage into must-fix / should-fix / clarification / discussion, present triage table, wait for user input, apply fixes after confirmation, draft replies.

---

User: "fix the PR feedback on my current branch"

Expected behavior: Detect PR from current branch, fetch comments, triage, present plan, apply approved changes, draft replies.

---

User: "respond to the code review on https://github.com/org/repo/pull/99"

Expected behavior: Fetch comments from PR #99, triage, resolve any ambiguities with user input, apply fixes and draft replies after confirmation.

Non-Trigger

User: "review this pull request #123"

Expected behavior: Do not use pr-comments-address. The user wants to review a PR, not address existing feedback. Use a PR review workflow instead.

---

User: "create a pull request for my branch"

Expected behavior: Do not use pr-comments-address. The user wants to create a new PR, not address comments on an existing one.

Troubleshooting

Skill Does Not Trigger

• Error: The skill is not selected when user asks to address PR comments.
• Cause: Request wording does not match trigger phrases (used "review PR" or "commit changes" instead of "address review", "fix feedback", "handle comments").
• Solution: Rephrase with explicit keywords: "address review comments", "fix PR feedback", "respond to review feedback" and retry.

No PR Found for Current Branch

• Error: gh pr view returns no PR for the current branch.
• Cause: Current branch does not have an open PR, or branch has not been pushed.
• Solution: Provide PR number or URL explicitly, or push the branch and create a PR first using agent-pr-creator.

No Unresolved Comments Found

• Error: The PR has no open review comments.
• Cause: All comments have already been resolved, or the PR has no reviews.
• Solution: Inform the user that there are no pending comments. If they expected comments, verify they specified the correct PR.

GitHub CLI Not Authenticated

• Error: gh commands fail with "not authenticated" or token errors.
• Cause: GitHub CLI is not logged in or auth token has expired.
• Solution: Run gh auth login to authenticate, then retry the skill.

Ambiguous Comment Intent

• Error: Cannot determine what the reviewer wants changed.
• Cause: Comment is vague, subjective, or depends on context not visible in the comment thread.
• Solution: Present the comment to the user with full context (file, line, code snippet) and ask explicitly what change they want to make. Do not assume intent.
