PR Retro Skill

Learn from PR outcomes by analyzing accept/reject patterns.

Overview

After a PR is merged or rejected, analyze what worked and what didn't to improve future contributions.

Output: .agents/learnings/YYYY-MM-DD-pr-{repo}-{outcome}.md

When to Use:

• After a PR is merged (capture success patterns)
• After a PR is rejected (understand why)
• After receiving significant review feedback
• Periodically to review contribution patterns

Workflow

1.  PR Discovery    -> Find the PR to analyze
2.  Outcome Analysis -> Merged/rejected/changes requested
3.  Feedback Extraction -> What did reviewers say?
4.  Pattern Identification -> What worked/didn't
5.  Lesson Extraction -> Reusable learnings
6.  Output -> Write retro document

Phase 1: PR Discovery

# If PR number provided
gh pr view <number> --json state,reviews,comments,mergedAt,closedAt

# Find recent PRs by you
gh pr list --state all --author @me --limit 10

# Find PRs to a specific repo
gh pr list -R <owner/repo> --state all --author @me --limit 10

Phase 2: Outcome Analysis

# Get PR outcome
gh pr view <number> --json state,mergedAt,closedAt,reviews

Phase 3: Feedback Extraction

# Get all review comments
gh pr view <number> --json reviews --jq '.reviews[] | "\(.author.login): \(.body)"'

# Get all comments
gh api repos/<owner>/<repo>/pulls/<number>/comments --jq '.[].body'

# Get requested changes
gh pr view <number> --json reviews --jq '.reviews[] | select(.state == "CHANGES_REQUESTED")'

Feedback Categories

Phase 4: Pattern Identification

Success Patterns (If Merged)

Failure Patterns (If Rejected)

Phase 5: Lesson Extraction

Lesson Template

## Lesson: [Title]

**Context**: [When does this apply?]

**Action**: [What to do differently?]

**Evidence**:
- PR #N: [quote or summary]

Common Lessons

Phase 6: Output
