grill-to-spec is a skill for Claude Code from retz8/pastiche. It costs 61 tokens per session (662 once invoked), scanned A, original, MIT.

A guide for turning a completed question-and-answer planning session into a written specification. A specification records what the task must cover and which decisions were made.

In plain words
What is it for?
Use it after a grilling session to save the agreed task scope, decisions, and explicitly identified open items in a spec file.
Why use it?
It keeps the document limited to confirmed decisions, without adding assumptions or implementation instructions.

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-to-spec 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 10d 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 to Spec

Convert a just-completed grill-me session into a spec file under _dev/docs/spec/.

File naming

Number first. Filename comes from the TODO number when available, otherwise name only. Do not ask the user about the path — derive it and proceed.

  • Task (**N.M** in TODO): _dev/docs/spec/task-<N.M>-<short-name>.md
  • Phase: _dev/docs/spec/phase-<N>-<short-name>.md
  • No task number available: _dev/docs/spec/<short-name>.md

Hard rules

  • Spec, not plan. Capture what was decided, not how to implement it. No task breakdown, no step-by-step, no file-by-file instructions.
  • Only what was locked in the grill. If a decision did not come up explicitly in the grilling conversation, do not include it. Do not infer, do not extend, do not add "for completeness."
  • No invented decisions. If the user did not state a preference on something, it is not in the spec. Surface it as an open item only if the user flagged it as open during grilling.
  • No implementation details. No code, no command lines, no file syntax, no per-step procedure. The spec is a high-level overview of the locked task scope and decisions.

Required structure

# <Task title>

<One- or two-sentence statement of what this spec covers. Reference the parent TODO item, phase, or OSS_SPEC section.>

## Scope

<Bulleted or short-prose statement of what is in scope for this task. Drawn from the grill, not invented.>

## Locked decisions

### 1. <Decision title>

<One short paragraph stating the decision as locked in the grill.>

### 2. <Decision title>

<...>

## Invariants

<Optional. Constraints the grill surfaced that apply throughout the task. Skip if none were raised.>

## Open items

<Optional. Only items the user explicitly flagged as deferred or unresolved during the grill. Skip if none.>

Process

  1. Re-read the grilling conversation in context. Identify every decision the user explicitly accepted, rejected, or modified.
  2. Derive the target path per the File naming rules above. Do not ask, do not confirm.
  3. Write the spec directly to that path using the required structure. Do not display the draft to the user beforehand — just write it.
  4. Report the written path in one line. The user will redirect if revisions are needed.

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.
