Parallel Worker Task

Assignment

$ARGUMENTS

Context

• Branch: !git branch --show-current
• Working directory: !pwd
• Repository: !basename $(git rev-parse --show-toplevel 2>/dev/null)

Workspace Rules

Check and follow project-specific CLAUDE.md:

if [ -f "CLAUDE.md" ]; then
  echo "=== Project CLAUDE.md ==="
  head -100 CLAUDE.md
fi

Base Branch Detection

Detect the base branch from workspace configuration (NOT always main/master):

# Find plugin directory for shared scripts
PLUGIN_DIR=""
for d in .claude-paralell-dev-plugin ../.claude-paralell-dev-plugin ../../.claude-paralell-dev-plugin "$HOME"/.claude/plugins/cache/claude-parallel-dev-plugin/pw/*; do
  [ -d "$d/scripts" ] && PLUGIN_DIR="$d" && break
done 2>/dev/null
[ -n "${PW_PLUGIN_DIR:-}" ] && PLUGIN_DIR="$PW_PLUGIN_DIR"

# Base branch detection (using shared script)
BASE_BRANCH=$("${PLUGIN_DIR}/scripts/detect-base-branch.sh" 2>/dev/null || echo "main")
echo "Base branch: $BASE_BRANCH"

Automatic Subagent Usage

MANDATORY: Before any implementation, you MUST use subagents:

1. ALWAYS use explorer subagent first to understand the codebase structure
2. For complex or risky changes, use analyzer subagent to assess impact
3. Never skip exploration - it prevents mistakes and ensures pattern compliance

Execution Process

Phase 1: Understanding (REQUIRED)

MANDATORY: Use explorer subagent to understand the codebase:

Use explorer subagent to find relevant files and patterns for this task

For complex changes, also use analyzer:

Use analyzer subagent to understand the architecture and dependencies

Key questions to answer:

• What existing patterns should I follow?
• What files need to be modified?
• Are there related tests I should update?

Phase 2: Planning

Before writing any code:

1. List files to create/modify
2. Identify patterns to follow
3. Plan minimal, focused changes
4. Consider edge cases

Phase 3: Implementation

Follow workspace conventions:

• Maintain existing code style
• Add type annotations where required
• Keep changes focused on the assigned task
• Do NOT modify files outside your scope

Apply Quality Skills:

• Follow /pw:code-quality standards (readability, maintainability, error handling)
• Follow /pw:security-review standards if handling auth, user input, or sensitive data

Phase 4: Verification

Run project-specific checks:

# Try common verification commands
if [ -f "Makefile" ] && grep -q "check" Makefile; then
  make check
elif [ -f "package.json" ]; then
  npm test 2>/dev/null || npm run test 2>/dev/null || true
elif [ -f "pyproject.toml" ]; then
  uv run pytest 2>/dev/null || uv run mypy . 2>/dev/null || true
else
  echo "No standard check command found - verify manually"
fi

Phase 5: Commit

Create atomic commit with conventional message:

git add .
git commit -m "$(cat <<'EOF'
feat: [brief description]

2. Check if it's a dependency on another worker
3. If critical, notify orchestrator
4. Do NOT proceed with incomplete implementation
