agent-planner
Plan a specialist AI agent before building. Produces an approved plan document (persona, features, workflow, constraints, out-of-scope) that the agent-builder skill consumes. Use when the user wants to design or plan an agent, even if they don't explicitly say "skill" or "prompt". Invoked via "/agent-planner" or naturally via phrases like "plan an agent", "design a custom Claude", "think through a specialist prompt", "start a new agent".
