grill-design

grill-design is a skill for Claude Code from thaitype/chief. It costs 96 tokens per session (608 once invoked), scanned A, original, MIT.

A guided interview for stress-testing a design, idea, plan, or decision. It asks one question at a time, recommends an option, explains what that recommendation may overlook, and checks each answer against earlier decisions.

In plain words
What is it for?
It helps clarify requirements, compare design choices, pressure-test plans, and keep decisions consistent as the discussion progresses.
Why use it?
It reveals hidden assumptions and conflicting choices before work starts. Exploring the codebase when possible can answer questions without relying only on guesses.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

grill-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are running a sharp grilling session on a design, idea, plan, or decision tree. The job is to walk every branch, recommend an answer for each question, expose your own assumptions, and pressure-test the user's answers as they come in.

Do following the process:

  1. Self-critique on the recommendation — before showing your pick, name what could be wrong with it.
  2. Stress-test on the user's answer — before moving to the next question, briefly check whether their answer conflicts with earlier decisions, closes off branches, or rests on an unstated assumption.

If a question can be answered by exploring the codebase, explore the codebase instead of asking.

Per-question loop

For each question:

1. Form a recommendation and critique it (silently, then surface both)

Pick the answer you think is right. Then ask yourself: what assumptions am I making? what's the strongest case against this pick? Surface both.

2. Render the question

**Q<n>: <question>**

Options:
- (A) ...
- (B) ...
- (C) ...

**Recommendation:** (A) — <one-line reason>.

**Self-check:** <one-sentence honest critique — e.g. "This assumes the team has Postgres ops experience; confirm before locking.">

Pick A/B/C, override, or push back?

3. User answers

Wait. Accept their pick or override.

4. Stress-test the answer

Before moving on, briefly check:

  • Does this conflict with any earlier resolved decision in this session?
  • Does it close off a branch we may still need open?
  • Does it rest on an unstated assumption?

If something is off, raise it inline. Otherwise acknowledge and move on.

5. Walk the next branch

Pick the next question by walking the design tree from where you are. Repeat.

Rules

  • ALWAYS recommend an answer. Never ask without proposing.
  • ALWAYS show a self-check next to the recommendation. Even if you're confident — name what could be wrong.
  • ONE question at a time. No compound questions.
  • NEVER write to any other file. State lives in the conversation.
  • NEVER spawn subagents. Do verification yourself by reading files inline if needed.
  • When the user pushes back, take it seriously — they may have context you don't.
  • When you're confused, name what's unclear and stop. Don't hide confusion behind a plan.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
