grill-plan

grill-plan is a skill for Claude Code, Codex from stark-ai-de/agent-skills. It costs 50 tokens per session (674 once invoked), scanned A, original, Apache-2.0.

A questioning process for testing a project plan, design, migration, release, or repository-maintenance proposal. It examines assumptions, risks, constraints, decision branches, approvals, and rollback expectations.

In plain words
What is it for?
Use it to pressure-test a plan, migration, architecture change, release, or maintenance proposal before execution.
Why use it?
It exposes unclear choices and validation gaps before implementation starts. This helps the team decide what must be resolved, approved, or made reversible.

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-plan 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 12d 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.

Grill Plan

Goal

Pressure-test a plan before execution so hidden assumptions, risky branches, missing approvals, and validation gaps become explicit decisions.

When to use

  • The user asks to be grilled, challenged, or questioned before implementation.
  • A migration, release, architecture change, or repo maintenance plan has unclear constraints.
  • The user wants decision branches clarified before work starts.

When not to use

  • Do not use when the user has already asked for implementation and the plan is clear.
  • Do not use for passive code review; use the relevant review skill.
  • Do not use to delay an urgent fix when the blocking decision is already known.

Inputs to inspect

  • Inspect the plan, issue, PR, design doc, repo constraints, validation commands, and approval boundaries.
  • Explore code or docs directly when a question can be answered from local evidence.

Inputs

  • The proposed plan, design, checklist, issue, PR, or release notes.
  • Repo constraints, workflow docs, validation commands, and known risks.
  • User goals, deadlines, approval boundaries, and rollback expectations.

Process

  1. Restate the objective and the riskiest assumption.
  2. Ask focused questions that change the plan if answered differently.
  3. Group questions by decision branch, not by curiosity.
  4. Identify missing evidence, approvals, rollback plans, and validation.
  5. Convert answers into a tightened plan or explicit blockers.
  6. Stop when the next action is clear enough to execute or reject.

Workflow

Use the process above, asking one high-leverage question at a time. End with a tightened plan, explicit blockers, or a decision that implementation should not proceed.

Decision points

  • If a question does not change the plan, omit it.
  • If the plan can fail irreversibly, require an approval and rollback answer.
  • If uncertainty is acceptable, mark it as a conscious risk instead of blocking.

Safety rules

  • Do not perform implementation while grilling unless the user switches modes.
  • Do not overwhelm the user with a long questionnaire; ask the highest-leverage questions first.
  • Do not treat assumptions as decisions.

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.
