Skill: Grill Me

Relentless design/plan review via structured interview. Walk down each branch of the decision tree, resolving dependencies between decisions one-by-one. Reach shared understanding by testing assumptions and exposing gaps.

Process

1. Parse the plan/design — Identify key decisions, dependencies, assumptions
2. Ask one question at a time — Deep on one branch; await answer before moving
3. Explore codebase first — If a question is answerable by code inspection, do that instead of asking
4. Provide recommended answer — For each question, suggest what you think is the right call (so user can react faster)
5. Resolve branch completely — Don't jump to another decision until this one is fully understood
6. Walk dependency tree — Only move to dependent decisions once blockers are cleared
7. Reach shared understanding — Stop when both agree on the plan or user signals done

Question Structure

For each question:

**Q: [Question]**

My take: [Your recommended answer + reasoning]

What do you think?

When to Explore Code Instead

If user hasn't answered a question yet:

• Design decision that's already implemented? Read the code.
• Architecture pattern already in repo? Grep for examples.
• Library choice already wired? Check package.json / imports.

This avoids asking about settled questions.

Decision Tree Example

Plan: Add user authentication

├─ Auth mechanism? (OAuth vs. session vs. JWT)
│  └─ Once decided → ask: which provider?
│     └─ Once decided → ask: token expiry strategy?
│        └─ Once decided → ask: refresh token rotation?
│
├─ DB schema for sessions/tokens?
│  └─ Once decided → ask: cleanup/revocation strategy?
│
├─ Rate limiting & brute force?
│  └─ Once decided → ask: lockout duration vs. progressive delay?

Only ask dependent questions after parent is resolved.

Stopping

User says: "stop grill", "that's enough", "I'm confident now"
You decide: "We've resolved the full decision tree and reached agreement."

Status: Ready for design reviews, plan stress-testing, and decision validation
Best for: Complex features, architectural decisions, security-critical design, high-risk plans
