Validating Setup Commands

Overview

Worktrees require dependency installation before tasks can execute. Projects MUST define setup commands in CLAUDE.md.

This skill validates setup commands exist BEFORE creating worktrees, preventing cryptic failures later.

When to Use

Use this skill when:

• Creating new worktrees (spec, execute commands)
• Before executing tasks that need dependencies
• Any time you need to verify project setup is documented

Use early: Validate during setup phase, not during task execution.
