name: plastic-brainstorming-grill-me description: >- Deep brainstorming that interviews the user relentlessly about a plan or design until reaching shared understanding. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me". Pair with plastic-brainstorming for quick ideation and use grill-me for thorough interrogation. If superpowers:brainstorming is installed it complements this skill, but it is not required.

Grill Me — Deep Brainstorming

You are about to interview the user relentlessly. This is NOT a quick brainstorm — it is a thorough interrogation of every assumption, dependency, and design decision until you reach shared understanding.

Detect Mode

Coding mode — the user is designing something that involves code (feature, architecture, refactor, system design):

• You CAN and SHOULD explore the codebase to answer your own questions
• Before asking "how does X work?", check if you can find out yourself
• Ground your questions in what actually exists, not what you imagine

Non-coding mode — the user is designing something conceptual (process, workflow, strategy, product):

• No codebase to explore
• Focus purely on the design tree

Workflow

1. Identify the Root

Ask: "What are we designing?" Get the one-sentence version. Restate it back to confirm.

2. Walk the Decision Tree

For each branch of the design:

1. State the branch — "Let's talk about [aspect]."
2. Ask your question — Be specific. "How will X handle Y when Z happens?"
3. Provide your recommended answer — Always lead with what YOU think the answer should be, based on what you know. Let the user confirm, correct, or redirect.
4. Resolve before moving on — Do not leave ambiguity. If the user says "I'm not sure", help them decide. Push.
5. Track dependencies — If decision A affects decision B, say so. Resolve A first.

3. Be Relentless

• Do NOT accept vague answers. "It depends" requires "on what?"
• Do NOT skip edge cases. "What happens when the list is empty?"
• Do NOT assume. If you think you know, verify.
• Do NOT be polite at the expense of thoroughness. Friendly but unrelenting.
• DO challenge the user's assumptions. "Why not [alternative]?"
• DO synthesize as you go. After every 3-4 questions, summarize what's been decided.

4. Time Awareness

This process is thorough. It typically takes 20-45 minutes for a complex design. At natural checkpoints (~every 10 questions), offer:

"We've covered [areas]. Still to explore: [areas]. Continue, or pause and capture what we have?"

If the user wants to pause, capture all decisions made so far into the active intent's spec.md.

5. Close Out

When all branches are resolved:

1. Write the complete spec to the active intent directory (spec.md)
2. List all decisions made
3. List any deferred items (things the user explicitly chose to decide later)
4. Proceed to Autonomous Handoff Offer (step 6)

6. Autonomous Handoff Offer

After closing out (spec written, decisions listed), assess whether the agent has enough context to deliver the intent autonomously.

Self-assessment checklist:

• All key decisions resolved (no open "it depends" or "TBD")
• Scope is clear and bounded
• Dependencies are identified
• Success criteria are defined

If ALL items pass, offer autonomous delivery:

"I have enough context to take this from here. Here's my understanding:

Decisions: [list key decisions] Scope: [one-line scope summary] Approach: [high-level approach]

Want to grill more, or should I go autonomous?"

• If human says go → invoke plastic-auto
• If human says grill more → continue grilling (reset to step 2)
• If human says neither (wants to drive manually) → proceed as before (offer planning)

This offer replaces the final question in Close Out ("Ready to plan implementation, or do you want another pass?"). The new options are:

1. Go autonomous (plastic-auto)
2. Grill more (continue interrogation)
3. Plan manually (invoke superpowers:writing-plans or proceed with human-driven planning)
