Create PR Skill

This skill handles the finalization phase of ticket resolution: pushing the branch and creating a pull request.

Capabilities

1. Push to remote with upstream tracking
2. Detect target branch from multiple sources
3. Create PR with auto-generated title and body
4. Draft mode support (when available)
5. Idempotent - skip if PR already exists

---

Target Branch Detection

Priority order for determining the PR target branch:

1. Explicit Argument

--base main

2. Status File (from worktree creation)

Read from .claude/feature/{ticket-id}/status.json:

{
  "options": {
    "base_branch": "develop"
  }
}

This is set by resolve-worktree.sh when creating the worktree, preserving the original base branch.

3. Ticket Metadata

Some tickets specify target branch:

• YouTrack: custom field "Target Branch" or "Fix versions", or parsed from Milestone
• GitHub: base branch in linked PR

Check in ticket.md or analysis.md for:

Target Branch: develop
Fix Version: release/2.0

4. Branch Pattern Matching

Detect from current branch name:

hotfix/* → main (or master)
release/* → main
feature/* → develop (if exists) or main
fix/* → develop (if exists) or main

5. Project Configuration

From .claude/ticket-config.json:

{
  "pr": {
    "default_target": "main"
  }
}

6. Git Default Branch

git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@'

7. Fallback

Try in order: main, master, develop

PR Title Generation

Format: {type}: {ticket_title} ({ticket_id})

Examples:

feat: Add CSV export for users (PROJ-123)
fix: Null pointer in login flow (PROJ-456)
refactor: Extract validation service (PROJ-789)

Type Detection

From branch prefix:

• feat/ → feat
• fix/ → fix
• refactor/ → refactor
• docs/ → docs
• chore/ → chore

---

PR Body Generation

Template:

## Summary

{Brief description from ticket or plan}

## Ticket

- **ID**: {ticket_id}
- **Source**: {YouTrack|GitHub}
- **Link**: {ticket_url}

Customization

From config:

{
  "pr": {
    "body_template": "custom template with {{ticket_id}} placeholders",
    "include_ticket_link": true
  }
}

---

Draft Mode

Detection

Check if repository supports draft PRs:

# GitHub - always supports drafts
gh pr create --draft ...

# GitLab - check version
# Bitbucket - check settings

Configuration

{
  "pr": {
    "draft_by_default": true
  }
}

Behavior

Mode	draft_by_default	Result
Auto	true	Create as draft
Auto	false	Create as ready
Interactive	-	Ask user

---

Process

Step 1: Pre-flight Checks

# Check if on feature branch (not main/master)
CURRENT_BRANCH=$(git branch --show-current)
if [[ "$CURRENT_BRANCH" =~ ^(main|master|develop)$ ]]; then
    echo "Error: Cannot create PR from protected branch"
    exit 1
fi

# Check for uncommitted changes
if [[ -n $(git status --porcelain) ]]; then
    echo "Warning: Uncommitted changes detected"
    # In interactive: ask to commit or stash
    # In auto: fail or stash
fi

# Check if remote exists
git remote get-url origin || exit 1

Step 2: Push Branch

# Push with upstream tracking
git push -u origin "$CURRENT_BRANCH"

If push fails:

• Check authentication
• Check branch protection rules
• Suggest git pull --rebase if behind

Step 3: Check Existing PR

# Check if PR already exists for this branch
EXISTING_PR=$(gh pr view "$CURRENT_BRANCH" --json number,url 2>/dev/null)

if [[ -n "$EXISTING_PR" ]]; then
    PR_URL=$(echo "$EXISTING_PR" | jq -r '.url')
    echo "PR already exists: $PR_URL"
    # Option: update existing PR description
    exit 0
fi

Step 4: Determine Target Branch

Apply detection priority (see above).

# Verify target branch exists
git ls-remote --heads origin "$TARGET_BRANCH" || {
    echo "Error: Target branch '$TARGET_BRANCH' not found"
    # Suggest alternatives
}

Step 5: Generate PR Content

Read from feature directory:

FEATURE_DIR=".claude/feature/$TICKET_ID"
TICKET_FILE="$FEATURE_DIR/ticket.md"
PLAN_FILE="$FEATURE_DIR/plan.md"

Extract:

• Title from ticket
• Summary from plan
• Changes from plan phases
• Validation from plan

Step 6: Create PR

# Draft mode
DRAFT_FLAG=""
if [[ "$DRAFT" == "true" ]]; then
    DRAFT_FLAG="--draft"
fi

# Create PR
gh pr create \
    --title "$PR_TITLE" \
    --body "$PR_BODY" \
    --base "$TARGET_BRANCH" \
    $DRAFT_FLAG

Step 7: Update Status

Update .claude/feature/{ticket-id}/status.json:

{
  "phases": {
    "finalize": "completed"
  },
  "pr": {
    "number": 123,
    "url": "https://github.com/owner/repo/pull/123",
    "draft": true,
    "target": "main"
  }
}
