mk:cook

mk:cook is a skill for Claude Code from ngocsangyem/MeowKit. It costs 75 tokens per session (4,643 once invoked), scanned A, original, MIT.

A workflow for designing interfaces between software components and deciding how features should behave. It covers resource shapes, messages, errors, permissions, compatibility, and deprecation.

In plain words
What is it for?
Use it to define API contracts, message formats, error responses, authorization requirements, compatibility rules, and deprecation plans.
Why use it?
It helps teams agree on observable behavior before implementation and reduces breaking changes for systems that consume an interface.

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

mk:cook 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/test-scripts.sh, scripts/validate-gate-1.sh, scripts/validate-gate-2.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Cook — Full Implementation Pipeline

Implementation entry adapter. .claude/workflow.yaml is the only lifecycle phase-sequence authority; this skill selects a profile, invokes the relevant owners, and presents the required gates. TDD is opt-in via --tdd.

Usage

/cook <natural language task OR plan path>
/cook "Add user auth" --fast
/cook "Build payment processor" --tdd       # Strict TDD enforced
/cook tasks/plans/260329-feature/plan.md --auto

Profiles: quick/--fast (inspect → edit → focused verify → summary), standard (plan if needed → implement → verify → review), release (standard + explicit mk:ship request), and high-assurance (--tdd --strict, with human gates). Flags: --interactive (default) | --fast | --parallel | --auto | --no-test | --tdd | --verify | --strict | --no-strict.

Quick runs do not create a plan, wiki candidate, memory entry, or ship action by default. They still stop if a risk flag or changed contract requires the standard profile.

Modifier flags (layer on any mode): --verify [LIGHT] (light browser/artifact check) | --strict [HEAVY] (full evaluator pass) | --no-strict (suppress auto-strict)

Concrete cost depends on the inner harness, model tier, and target surface; treat [LIGHT] vs [HEAVY] as relative ordering only.

--verify is advisory (does not block ship). --strict is a hard gate (FAIL blocks ship and routes back to Phase 3).

--advice (composable, off by default) — opt-in strategic supervision for one run. At named checkpoints (GUIDE after Gate 1, RESCUE on a stall or contradiction, REVIEW after Verify and before the reviewer, RECHECK after a correction; hard cap 5) the athena agent assesses the situation, recommends an operational path inside the locked scope, and may return the work for correction. It never approves: Gate 1 and Gate 2 remain human, the reviewer keeps its verdict, and supervision counts as no verification. Without the flag there are zero calls and no state is written. Checkpoints: references/workflow-steps.md → Advice Checkpoints. Contract: .claude/rules-conditional/advice-supervision-rules.md (load only when the flag is present).

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.
