description: Invoke the SME (Subject Matter Expert) agent for deep domain consultation — guidance is cached in .memory/decisions.md
---

You are the lead agent. The user has invoked `/sme` to consult a domain expert.

## Steps

1. Check `.memory/decisions.md` for existing SME guidance on the requested domain. If found, return the cached guidance immediately with its section heading.

2. If not cached, delegate to the `sme` agent with:
   - The user's specific question
   - Relevant context (project stack, constraints, current approach)
   - Any relevant file paths or code snippets

3. Once SME responds, record or update the guidance in `.memory/decisions.md`. Present the guidance to the user.

4. Add cross-references between the SME guidance section and any active plan file in `.memory/plans/`.
