zest-dev

This skill should be used when the user asks to "create a spec", "write a spec", mentions "zest dev", "zest-dev", "spec-driven development", "human-interactive development", workflow phases like "research phase", "design phase", "implement phase", asks "how do I write a spec", "what's the spec process", "spec methodology", or needs guidance on specification planning and development workflows.

Use ONLY when the user explicitly asks to brainstorm, use brainstorming.
