grill

grill is a skill for Claude Code from Data-Wise/craft. It costs 115 tokens per session (1,834 once invoked), scanned B, original, MIT.

A questioning tool that stress-tests a specification, plan, or topic one question at a time. It looks for missing details, contradictions, and unresolved dependencies before implementation.

In plain words
What is it for?
Use it to interrogate a proposal, review a plan adversarially, resolve open decisions, or create a durable decision record.
Why use it?
It helps expose design problems while they are still cheap to fix. This can make later planning and coding more deliberate.

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 B, and why

grill scanned grade B with 1 finding 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 4d 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.

Grill — Interrogate Before Building

Convergent counterpart to brainstorm. Brainstorm is divergent — it GENERATES options and expands the space. Grill is convergent — it INTERROGATES a position to find gaps, contradictions, and unresolved dependencies before you implement.

Use grill to stress-test a spec/plan (or a bare topic) until every load-bearing branch of the design tree is resolved, then capture the locked decisions as a durable ledger that feeds /craft:plan/do.

Boundary With Adjacent Skills

Skill Role
grill (this) Convergent — interrogates a position, captures a GRILL-*.md decision ledger
brainstorm Divergent — generates options, captures a BRAINSTORM/SPEC
prompt-refiner Sharpens a bare/quoted topic before grilling (default-on for topics)
plan-orchestrator / --orch Turns the locked ledger + spec into an ORCHESTRATE artifact

Inputs (flags owned by the commands/grill.md shim)

  • target — spec/plan path, a quoted topic, or empty (detect from context).
  • --bound N — stop after N decision branches (quick gate; used by orchestrate Step 0.5).
  • --no-capture — skip writing a GRILL-* file; return decisions inline (embedded callers).
  • --yes / --non-interactive — auto-accept every Recommended answer, zero AskUserQuestion prompts.
  • --refine / --no-refine — refine a topic via prompt-refiner before grilling (default-on for topics; skipped for a path).
  • --no-tests / --no-docs — suppress the auto-emitted test-plan / Documentation sections.

Procedure

Step 1: Resolve the target

  • Path argument → load that artifact (spec/plan/ORCHESTRATE/diff) and interrogate it.
  • Quoted topic → sketch a 3–5 bullet skeleton, show it, then interrogate the skeleton.
  • Empty → detect from .STATUS, branch name, and recent commits; confirm the target before grilling.

Step 2: Codebase-first sweep (read-then-confirm)

When the argument is a quoted/bare topic, run prompt-refiner on it first (default-on; --no-refine skips). When the argument is a path, skip refine entirely.

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.

grill is a skill published in the GitHub repository Data-Wise/craft (4 stars, last pushed 4d ago), licensed MIT. It adds 115 tokens to every session and 1,834 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
