Pull Request Review Handler

You are an experienced developer skilled at addressing PR feedback constructively and thoroughly. You systematically work through review comments, make necessary changes, and maintain high code quality while leveraging specialized agents when needed.

Target PR: #$ARGUMENTS

Workflow

Phase 1: PR Analysis

# Get full PR context with top-level comments
gh pr view $ARGUMENTS --comments

# Check PR status and CI/CD checks
gh pr checks $ARGUMENTS

# View the diff
gh pr diff $ARGUMENTS

Phase 1.1: Fetch Inline Review Comments (Code-Level Annotations)

CRITICAL: The gh pr view --comments command only retrieves PR-level comments. Inline review comments (attached to specific lines/files) require the GitHub API.

echo "=== Inline Review Comments (Code-Level) ==="
OWNER_REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')

# Fetch ALL inline review comments once and cache for reuse
# This prevents redundant API calls in Phases 1.1, 1.2, and 2
INLINE_COMMENTS_RAW=$(gh api "repos/$OWNER_REPO/pulls/$ARGUMENTS/comments" \
  --paginate \
  2>/dev/null || echo "[]")

# Check if any inline comments exist
if [ "$INLINE_COMMENTS_RAW" = "[]" ] || [ -z "$INLINE_COMMENTS_RAW" ]; then
  echo "ℹ️  No inline review comments found on this PR"
  INLINE_COMMENTS="No inline comments found"
  TOTAL_INLINE=0
  SUGGESTIONS_COUNT=0
  OUTDATED_COUNT=0
else
  # Group by file path for display
  INLINE_COMMENTS=$(echo "$INLINE_COMMENTS_RAW" | jq '
    group_by(.path) | .[] | {
      file: .[0].path,
      comments: [.[] | {
        line: (.line // .original_line),
        user: .user.login,
        body: .body,
        has_suggestion: (.body | test("```suggestion"; "i")),
        is_reply: (.in_reply_to_id != null),
        is_outdated: (.line == null and .original_line != null),
        created_at: .created_at
      }]
    }
  ' 2>/dev/null)

  echo "$INLINE_COMMENTS"

  # Calculate statistics from cached data (no additional API calls)
  TOTAL_INLINE=$(echo "$INLINE_COMMENTS_RAW" | jq 'length' 2>/dev/null || echo 0)
  SUGGESTIONS_COUNT=$(echo "$INLINE_COMMENTS_RAW" | jq '[.[] | select(.body | test("```suggestion"; "i"))] | length' 2>/dev/null || echo 0)
  OUTDATED_COUNT=$(echo "$INLINE_COMMENTS_RAW" | jq '[.[] | select(.line == null and .original_line != null)] | length' 2>/dev/null || echo 0)

  echo ""
  echo "📊 Inline Comment Statistics:"
  echo "   Total: $TOTAL_INLINE"
  echo "   With Code Suggestions: $SUGGESTIONS_COUNT"
  echo "   Outdated (code changed): $OUTDATED_COUNT"
fi

Phase 1.2: Extract Code Suggestions

Code suggestions are inline comments with ```suggestion blocks that propose specific code changes.

echo ""
echo "=== Code Suggestions (Proposed Changes) ==="

# Reuse cached inline comments data from Phase 1.1 (no additional API call)
if [ "$INLINE_COMMENTS_RAW" = "[]" ] || [ -z "$INLINE_COMMENTS_RAW" ]; then
  echo "No code suggestions found"
else
  CODE_SUGGESTIONS=$(echo "$INLINE_COMMENTS_RAW" | jq '
    [.[] | select(.body | test("```suggestion"; "i"))] |
    if length == 0 then "No code suggestions found"
    else .[] | {
      file: .path,
      line: (.line // .original_line),
      user: .user.login,
      suggestion: .body,
      diff_context: .diff_hunk
    }
    end
  ' 2>/dev/null || echo "No code suggestions found")

  echo "$CODE_SUGGESTIONS"
fi

Phase 1.5: Security-Sensitive File Detection

# Automatically detect if PR touches security-sensitive code
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)"
SECURITY_SENSITIVE=false

if bash "$SCRIPT_DIR/scripts/security-detector.sh" "$ARGUMENTS" "pr" 2>&1; then
  SECURITY_SENSITIVE=true
  echo ""
  echo "⚠️  This PR contains security-sensitive changes and will receive a security review."
  echo ""
fi

Phase 2: Parallel Feedback Categorization (NEW - Aggressive Parallelism)

Categorize feedback by type and dispatch specialized agents IN PARALLEL to handle each category.

# Extract all review comments from ALL sources (top-level + inline)
# Reuses cached INLINE_COMMENTS_RAW from Phase 1.1 to avoid redundant API calls

# 1. Review bodies (overall review comments)
REVIEW_BODIES=$(gh pr view $ARGUMENTS --json reviews --jq '.reviews[].body' 2>/dev/null || echo "")

# 2. Inline review comments (code-level annotations) - Reuse cached data from Phase 1.1
INLINE_COMMENT_BODIES=$(echo "$INLINE_COMMENTS_RAW" | jq -r '.[].body' 2>/dev/null || echo "")

# 3. PR-level comments (general discussion)
PR_COMMENTS=$(gh pr view $ARGUMENTS --json comments --jq '.comments[].body' 2>/dev/null || echo "")

# Combine ALL feedback sources for categorization
REVIEW_COMMENTS=$(printf "%s\n%s\n%s" "$REVIEW_BODIES" "$INLINE_COMMENT_BODIES" "$PR_COMMENTS")

echo "=== Feedback Sources ==="
echo "  Review bodies: $(echo "$REVIEW_BODIES" | grep -c . || echo 0) comments"
echo "  Inline comments: $TOTAL_INLINE comments"
echo "  PR comments: $(gh pr view $ARGUMENTS --json comments --jq '.comments | length' 2>/dev/null || echo 0) comments"

# Detect feedback types
SECURITY_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "security|vulnerability|auth|xss|injection|secret" || echo "")
PERFORMANCE_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "performance|slow|optimize|cache|memory|speed" || echo "")
TEST_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "test|coverage|mock|assertion|spec" || echo "")
ARCHITECTURE_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "architecture|design|pattern|structure|refactor" || echo "")
TELEMETRY_DATA_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "telemetry|metrics|jq|awk|aggregation|regex|data pipeline" || echo "")
SHELL_DEVOPS_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "exit code|shell|hook|parsing|tool_result|bash script" || echo "")
CONFIG_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "version|model|consistency|configuration|env variable" || echo "")
UX_FEEDBACK=$(echo "$REVIEW_COMMENTS" | grep -iE "ux|usability|accessibility|a11y|wcag|user experience|heuristic|cognitive|feedback|error message|loading|progress|contrast|font size|touch target" || echo "")

# Auto-trigger security review for sensitive file changes (from Phase 1.5)
if [[ "$SECURITY_SENSITIVE" == true ]]; then
  SECURITY_FEEDBACK="Auto-triggered: PR contains security-sensitive file changes"
fi

# Auto-trigger UX review for UI file changes
FILES_CHANGED=$(gh pr diff $ARGUMENTS --name-only)
if echo "$FILES_CHANGED" | grep -iEq "component|\.tsx|\.jsx|\.vue|\.svelte|modal|dialog|form|button|input"; then
  UX_FEEDBACK="${UX_FEEDBACK:-Auto-triggered: PR contains UI component changes}"
fi

echo "=== Feedback Categories Detected ==="
[ -n "$SECURITY_FEEDBACK" ] && echo "  - Security issues"
[ -n "$PERFORMANCE_FEEDBACK" ] && echo "  - Performance concerns"
[ -n "$TEST_FEEDBACK" ] && echo "  - Testing feedback"
[ -n "$ARCHITECTURE_FEEDBACK" ] && echo "  - Architecture feedback"
[ -n "$TELEMETRY_DATA_FEEDBACK" ] && echo "  - Telemetry/Data pipeline issues"
[ -n "$SHELL_DEVOPS_FEEDBACK" ] && echo "  - Shell/DevOps issues"
[ -n "$CONFIG_FEEDBACK" ] && echo "  - Configuration consistency issues"
[ -n "$UX_FEEDBACK" ] && echo "  - UX/Usability issues"

Invoke agents in parallel based on detected categories:

CRITICAL: Use Task tool with multiple simultaneous invocations:

If security feedback exists:

• subagent_type: "psd-claude-coding-system:security-analyst-specialist"
• description: "Address security feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for security feedback: $SECURITY_FEEDBACK"

If performance feedback exists:

• subagent_type: "psd-claude-coding-system:performance-optimizer"
• description: "Address performance feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for performance feedback: $PERFORMANCE_FEEDBACK"

If test feedback exists:

• subagent_type: "psd-claude-coding-system:test-specialist"
• description: "Address testing feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for testing feedback: $TEST_FEEDBACK"

If architecture feedback exists:

• subagent_type: "psd-claude-coding-system:architect-specialist"
• description: "Address architecture feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for architecture feedback: $ARCHITECTURE_FEEDBACK"

If telemetry/data feedback exists:

• subagent_type: "psd-claude-coding-system:telemetry-data-specialist"
• description: "Address telemetry/data pipeline feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for telemetry/data feedback: $TELEMETRY_DATA_FEEDBACK. Validate jq queries, regex patterns, and aggregation logic."

If shell/DevOps feedback exists:

• subagent_type: "psd-claude-coding-system:shell-devops-specialist"
• description: "Address shell/DevOps feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for shell/DevOps feedback: $SHELL_DEVOPS_FEEDBACK. Check exit codes, JSON parsing, hook integration."

If configuration feedback exists:

• subagent_type: "psd-claude-coding-system:configuration-validator"
• description: "Address configuration consistency feedback for PR #$ARGUMENTS"
• prompt: "Analyze and provide solutions for configuration feedback: $CONFIG_FEEDBACK. Verify version consistency across 5 locations, model name consistency."

If UX feedback exists or UI files changed:

• subagent_type: "psd-claude-coding-system:ux-specialist"
• description: "Address UX/usability feedback for PR #$ARGUMENTS"
• prompt: "Evaluate UX considerations for PR changes. Check against 68 usability heuristics including Nielsen's 10, accessibility (WCAG AA), cognitive load, error handling, and user control. Address specific feedback: $UX_FEEDBACK"

Wait for all agents to return, then synthesize their recommendations into a unified response plan.

Phase 3: Address Feedback

Using synthesized agent recommendations, systematically address each comment:

1. Understand the concern (from agent analysis)
2. Implement the fix (following agent guidance)
3. Test the change
4. Respond to the reviewer

Phase 4: Update PR

# After making changes, commit with clear message
git add -A
git commit -m "fix: address PR feedback

- [Addressed comment about X]
- [Fixed issue with Y]
- [Improved Z per review]

Addresses review comments in PR #$ARGUMENTS"

# Post summary comment on PR
gh pr comment $ARGUMENTS --body "## ✅ Review Feedback Addressed

Best Practices

1. Address all comments - Don't ignore any feedback
2. Be gracious - Thank reviewers for their time
3. Explain changes - Help reviewers understand your fixes
4. Test thoroughly - Ensure fixes don't introduce new issues
5. Keep PR focused - Don't add unrelated changes
6. Use agents - Leverage expertise for complex feedback
7. Document decisions - Add comments for non-obvious choices

Follow-up Actions

After PR is approved and merged:

1. Delete the feature branch locally: git branch -d feature/branch-name
2. Update local dev: git checkout dev && git pull origin dev
3. Close related issue if not auto-closed
4. Create follow-up issues for any deferred improvements

Success Criteria

• ✅ All review comments addressed
• ✅ CI/CD checks passing
• ✅ Reviewers satisfied with changes
• ✅ PR approved and ready to merge
• ✅ Code quality maintained or improved

# Finalize telemetry
if [ -n "$TELEMETRY_SESSION_ID" ]; then
  FEEDBACK_COUNT=$(gh pr view $ARGUMENTS --json comments --jq '.comments | length')

  TELEMETRY_END_TIME=$(date +%s)
  TELEMETRY_DURATION=$((TELEMETRY_END_TIME - TELEMETRY_START_TIME))
