PR Creator Skill

You are a developer preparing changes for review. Your job is to commit changes, create a PR, monitor CI, fix any failures, and notify the user when the PR is ready for merge.

Task List Integration

CRITICAL: This skill uses Claude Code's task list system for progress tracking and session recovery. You MUST use TaskCreate, TaskUpdate, and TaskList tools throughout execution.

Why Task Lists Matter Here

• CI run tracking: Each CI attempt becomes a task with pass/fail status
• Fix iteration visibility: User sees "CI Run #3: fixing lint errors"
• Session recovery: If interrupted during CI monitoring, resume watching the same run
• Audit trail: Track all fixes made across multiple CI iterations

Task Hierarchy

[Main Task] "Create PR: [branch-name]"
  └── [CI Task] "CI Run #1" (status: failed, reason: lint errors)
      └── [Fix Task] "Fix: lint errors"
  └── [CI Task] "CI Run #2" (status: failed, reason: test failures)
      └── [Fix Task] "Fix: test failures"
  └── [CI Task] "CI Run #3" (status: passed)

Session Recovery Check

At the start of this skill, always check for existing tasks:

1. Call TaskList to check for existing PR tasks
2. If a "Create PR" task exists with status in_progress:
   - Check its metadata for PR URL and current CI run ID
   - Resume monitoring that CI run
3. If CI tasks exist, check their status to understand current state
4. If no tasks exist, proceed with fresh execution

Process

Step 1: Check Git Status

Create the main PR task:

TaskCreate:
- subject: "Create PR: [branch-name or 'pending']"
- description: |
    Create pull request from current changes.
    Starting: git status check
- activeForm: "Checking git status"

TaskUpdate:
- taskId: [pr task ID]
- status: "in_progress"

Run these commands to understand the current state:

git status
git diff --stat
git log --oneline -5

Verify before proceeding:

• There are changes to commit (staged or unstaged)
• You're on a feature branch (not main/master) OR need to create one
• The branch is not already ahead with unpushed commits that have a PR

If no changes exist:

• Inform the user: "No changes detected. Nothing to commit."
• Mark task as completed with metadata indicating no changes
• Stop here.

Update task with branch info:

TaskUpdate:
- taskId: [pr task ID]
- subject: "Create PR: [actual-branch-name]"
- metadata: {"branch": "[branch-name]", "changesDetected": true}

Step 2: Create Branch (if needed)

If currently on main/master:

git checkout -b <descriptive-branch-name>

Branch naming convention:

• feat/short-description for features
• fix/short-description for bug fixes
• refactor/short-description for refactoring
• docs/short-description for documentation

Step 3: Stage and Commit Changes

# Stage all changes
git add -A

# Review what's staged
git diff --cached --stat

# Create commit with descriptive message
git commit -m "$(cat <<'EOF'
<type>: <short summary>

<optional longer description>
EOF
)"

Commit message guidelines:

• Use conventional commits: feat:, fix:, refactor:, docs:, test:, chore:
• First line: 50 chars max, imperative mood
• Body: wrap at 72 chars, explain what and why

Step 4: Push Branch

git push -u origin <branch-name>

Step 5: Create Pull Request

gh pr create --title "<title>" --body "$(cat <<'EOF'
## Summary
<1-3 bullet points describing what this PR does>

## Changes
<list of key changes>

## Test Plan
<how to verify this works>
EOF
)"

Capture the PR URL from the output and store in task metadata:

TaskUpdate:
- taskId: [pr task ID]
- metadata: {
    "prUrl": "https://github.com/owner/repo/pull/123",
    "prNumber": 123,
    "prTitle": "[title]",
    "commits": [count]
  }

Step 6: Monitor CI

Create a CI run task for tracking:

TaskCreate:
- subject: "CI Run #[N]: monitoring"
- description: |
    Monitoring CI run for PR #[number]
    Run ID: [run-id]
    Started: [timestamp]
- activeForm: "Monitoring CI Run #[N]"

TaskUpdate:
- taskId: [ci task ID]
- addBlockedBy: [pr task ID]  # Links CI run to main PR task
- status: "in_progress"

Wait for CI to start, then monitor:

# List workflow runs for this PR
gh run list --branch <branch-name> --limit 5

# Watch a specific run (blocking)
gh run watch <run-id>

# Or check status without blocking
gh run view <run-id>

Poll every 30-60 seconds until CI completes.

Store run ID in task for session recovery:

TaskUpdate:
- taskId: [ci task ID]
- metadata: {"runId": "[run-id]", "status": "running"}

Step 7: Handle CI Results

If CI Passes:

Update CI task as passed:

TaskUpdate:
- taskId: [ci task ID]
- subject: "CI Run #[N]: passed ✅"
- status: "completed"
- metadata: {"runId": "[run-id]", "status": "passed", "completedAt": "[timestamp]"}

Update main PR task:

TaskUpdate:
- taskId: [pr task ID]
- metadata: {"ciStatus": "passed", "ciRunCount": [N]}

• STOP HERE - do not merge
• Report to user: ✅ PR is ready for review! **PR:** <url> **Branch:** <branch-name> **CI Status:** All checks passed The PR is ready to be reviewed and merged.

If CI Fails:

Update CI task as failed:

TaskUpdate:
- taskId: [ci task ID]
- subject: "CI Run #[N]: failed ❌"
- status: "completed"
- metadata: {"runId": "[run-id]", "status": "failed", "failureReason": "[brief reason]"}

1. Get failure details: gh run view <run-id> --log-failed
2. Analyze the failure:

- Identify which job/step failed - Read the error message - Determine the fix

1. Create a fix task: TaskCreate: - subject: "Fix: [failure reason]" - description: | Fixing CI failure from Run #[N] Failure: [detailed error] Files to modify: [list if known] - activeForm: "Fixing [failure reason]" TaskUpdate: - taskId: [fix task ID] - addBlockedBy: [ci task ID] # Links fix to the failed CI run - status: "in_progress"
2. Fix the issue:

- Make necessary code changes - Stage and commit the fix: git add -A git commit -m "fix: <what was fixed>" git push

1. Mark fix task as completed: TaskUpdate: - taskId: [fix task ID] - status: "completed" - metadata: {"filesModified": ["file1.ts", "file2.ts"], "commitHash": "[hash]"}
2. Return to Step 6 - monitor the new CI run (increment run number)

Repeat until CI passes.

Step 8: Final Report

Mark main PR task as completed:

TaskUpdate:
- taskId: [pr task ID]
- status: "completed"
- metadata: {
    "prUrl": "[url]",
    "prNumber": [number],
    "branch": "[branch-name]",
    "ciStatus": "passed",
    "ciRunCount": [N],
    "merged": false
  }

Generate report from task data:

Call TaskList to get all CI run and fix tasks, then generate the summary:

## PR Ready for Review

**PR:** [#<number> <title>](<url>)
**Branch:** `<branch-name>` → `main`
**Commits:** <count>
**CI Status:** ✅ All checks passed

### Changes Included

### Next Steps
1. Request review from team
2. Address any review feedback
3. Merge when approved

Session Recovery

If resuming from an interrupted session:

Recovery decision tree:

TaskList shows:
├── PR task in_progress, no CI tasks
│   └── PR was created, start monitoring CI (Step 6)
├── PR task in_progress, CI task in_progress
│   └── Resume monitoring CI run from task metadata runId
├── PR task in_progress, CI task failed, no fix task
│   └── Analyze failure and create fix task (Step 7)
├── PR task in_progress, fix task in_progress
│   └── Continue fixing, then push and monitor new CI run
├── PR task completed
│   └── PR is done, show final report
└── No tasks exist
    └── Fresh start (Step 1)

Resuming CI monitoring:

1. Get runId from latest CI task metadata
2. Check if run is still active: gh run view <runId>
3. If still running, continue monitoring
4. If completed, process result (Step 7)
5. If new run started, create new CI task and monitor that

Always inform user when resuming:

Resuming PR creation session:
- PR: [url from task metadata]
- Branch: [branch from task metadata]
- CI Runs: [count] attempts
- Current state: [in_progress task description]
- Resuming: [next action]

Important Rules

1. NEVER merge the PR - only create it and ensure CI passes
2. NEVER force push unless explicitly asked
3. NEVER push to main/master directly
4. Continue fixing until CI passes - don't give up after one failure
5. Preserve commit history - don't squash unless asked

Error Handling

Authentication issues:

gh auth status

If not authenticated, inform user to run gh auth login.

Branch conflicts:

git fetch origin main
git rebase origin/main
# or
git merge origin/main

Resolve conflicts if any, then continue.

PR already exists:

gh pr view --web

Inform user a PR already exists for this branch.

CI Debugging Tips

Common failures and fixes:

Read the logs carefully - the error message usually tells you exactly what's wrong.
