PR Comment Triage

Triage and resolve PR review comments from humans and bots in a structured four-phase workflow.

Scope

• Use for: unresolved review threads on open PRs, both human and bot comments
• Skip: closed PRs, PRs with no unresolved threads, draft PRs unless explicitly requested

Workflow

Copy this checklist to track progress:

PR comment triage progress:
- [ ] Phase 1: Fetch unresolved review threads, reviews, and comments
- [ ] Phase 2: Triage and classify all items
- [ ] Phase 3: Write fix plan and get approval
- [ ] Phase 4: Execute fixes and resolve threads

Phase 1: Fetch

Load references/github-api.md for query templates.

1. Identify the PR — auto-detect from current branch (gh pr view --json number) or accept an explicit PR number argument
2. Extract owner/repo — gh repo view --json owner,name
3. Fetch all review threads — use the GraphQL reviewThreads query with pagination. Collect every thread, then filter to isResolved == false
4. Fetch PR reviews — use the REST reviews endpoint. Collect all reviews with their state, body, and author. Pay attention to CHANGES_REQUESTED reviews with body text — these contain the reviewer's summary of what needs to change
5. Fetch issue-level comments — use the REST endpoint for all PR conversation comments. Do not filter by author — bot comments from github-actions[bot] may contain actionable findings (DangerJS warnings, schema compatibility checks)
6. Early exit — if zero unresolved threads, zero actionable reviews, and zero actionable issue comments, report "No unresolved review items found" and stop

Output: three lists — unresolved threads, reviews with content, and issue-level comments.

Phase 2: Triage

Load references/bot-patterns.md for detection and parsing rules.

For each item across all three sources:

1. Identify author type — human or bot. For bots, classify by content first, then username. See references/bot-patterns.md for detection rules, severity parsing, and false positive patterns
2. Skip noise — auto-classify noise items per bot-patterns reference (linear linkbacks, vercel deployments, Devin "no issues" reviews, changeset releases, event-lib triggers)
3. Parse severity — extract from bot-specific format (emoji, SVG, HTML tables). Human comments: default to Major for CHANGES_REQUESTED, Minor for APPROVED + question
4. Deduplicate — group inline comments on the same file within a 3-line range. Keep the highest-severity, most-actionable comment. Mark others as ignore-duplicate
5. Classify each remaining item:

- Category: bug, security, performance, style, correctness, docs, test-coverage - Severity: critical, major, minor, nitpick - Confidence: high (human or multi-bot), medium (single bot, clear issue), low (single bot, likely false positive) - Disposition: fix or ignore (with reason) - Source type: thread (resolvable), conversation (reply-only)

1. Flag ignore candidates with specific reasoning:

- Pre-existing code not changed in this PR - Bot flagged.md, config, lock, or migration files (no security implications) - Contradicts project CLAUDE.md/AGENTS.md conventions - Outdated thread where code has changed substantially - Noise bot boilerplate or badge injection

Human comments are never auto-ignored. Always classify as fix unless clearly already resolved or the reviewer explicitly marked it as optional ("up to you", "but not blocking").

Phase 3: Plan

Load references/fix-plan-template.md for the output template.

1. Create plan file — write to .claude/scratchpad/pr-{N}-review-plan.md (create directory if needed)
2. Issues to Fix — ordered by severity (critical first), each with thread ID, file:line, author, category, finding, fix approach, and commit group label
3. Conversation Items — issue-level comments and review bodies that need fixes but have no thread ID. These get a reply but no resolve mutation
4. Ignored — each with thread ID or comment ID, author, reason, and the brief reply to post when resolving
5. Summary table — disposition-by-severity matrix for quick scanning
6. Present to user — print a summary showing counts (N to fix, K conversation items, M to ignore) and ask for approval

Stop here. Do not proceed to Phase 4 until the user reviews and approves the plan.

The user may edit the plan — move items between fix/conversation/ignore, change priorities, add notes. Re-read the plan file before executing.

Phase 4: Execute

After user approval, re-read .claude/scratchpad/pr-{N}-review-plan.md in case it was edited.

4a. Resolve ignored threads:

For each ignored item that has a thread ID:

1. Post a brief reply explaining the decision
2. Resolve the thread via GraphQL mutation

Use concise, specific reasons:

• "Duplicate of thread addressing the same finding — resolving."
• "Contradicts project convention (see CLAUDE.md) — resolving."
• "Outdated thread — code has been refactored. Resolving."
• "CI notification — not actionable. Resolving."

For ignored noise without a thread ID (issue-level bot comments), do nothing — no reply needed.

4b. Fix real issues:

Group fixes by commit group label from the plan. For each group:

• If fixes touch independent files, launch parallel subagents (one per file group)
• If fixes touch the same file or overlapping lines, execute sequentially
• Each subagent reads the file, applies the fix, and verifies correctness

Subagent prompt template:

Fix the following PR review issue(s) on branch {BRANCH}:

Issue: {finding}
File: {path}:{line}
Fix approach: {fix_approach}

Read the file, understand the surrounding context, and make the fix.
After fixing, verify the change is correct.
Do NOT touch unrelated code.

4c. Commit and push:

• Run project lint/test commands if available
• One commit per logical fix group, message format: fix({scope}): {description}
• Push the branch

4d. Resolve and reply:

• Resolved threads: post reply ("Fixed in latest push.") then resolve via GraphQL
• Conversation items: post reply acknowledging the fix
• Issue-level comments have no resolve mechanism — the reply is the acknowledgment

4e. Verify:

• Re-fetch threads from GitHub (fresh API call) to confirm zero unresolved remain
• Check CI status with gh pr checks
• Report results to the user

Anti-patterns

• Resolving threads without posting a reply — reviewers need to see the reasoning
• Auto-ignoring human comments — always classify for user review
• Fixing items the plan marked as ignore without approval
• One commit per individual comment — group related fixes by commit group label
• Pushing before verifying lint/test pass locally
• Skipping Phase 3 approval — the fix plan is the quality gate
• Classifying github-actions[bot] as always noise — it is a shared identity used by DangerJS, schema checkers, and other active tools. Classify by content.
• Filtering issue-level comments to humans only — bot comments from DangerJS and schema checkers are actionable
