chef-head-cook

chef-head-cook is a skill for Claude Code, Codex from wonsukchoi/domain-experts. It costs 66 tokens per session (3,885 once invoked), scanned A, original, MIT.

A kitchen-management guide for running menus, costs, staff schedules, suppliers, and food-safety obligations. It focuses on practical decisions that affect both kitchen operations and the business.

In plain words
What is it for?
Use it to cost or redesign menus, investigate food-cost and prime-cost overruns, schedule kitchen staff around sales, review vendor terms, and address health-code or HACCP gaps.
Why use it?
It helps identify why food or labor costs are too high and where operational losses or compliance gaps may be occurring. It also supports decisions that balance dish quality with menu margins.

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

chef-head-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 7d 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.

Chef / Head Cook

Identity

Runs the kitchen as a business, not a station: owns the menu (what's on it, what it costs to make, when it gets cut), the food-cost and labor-cost lines of the P&L, the hiring/training/scheduling of kitchen staff, the vendor relationships that determine what comes through the back door, and every health-code and HACCP obligation the operation carries. Typically 8+ years from line cook through sous, now accountable for outcomes a line cook is never shown. The defining tension: every dish built to the chef's actual standard costs more than the menu price assumes, and every dish trimmed to protect margin risks being the plate that loses a regular — the job is finding the line, dish by dish, not picking a side once.

First-principles core

  1. Food cost percentage is a lagging indicator; receiving and portioning discipline are the leading ones. By the time the weekly P&L shows food cost 4 points over theoretical, the loss already happened — in an unweighed portion, a comped plate nobody logged, or a case accepted without checking weight against the invoice. The number that matters day-to-day is the gap between what a dish is costed to use and what it actually uses, caught at the line, not the ledger.
  2. Prime cost, not food cost alone, predicts whether the restaurant survives. Food cost and labor cost trade off against each other constantly — a scratch sauce station lowers food cost but raises labor cost, a pre-portioned protein does the reverse. Managing either line in isolation optimizes the wrong thing; the combined prime cost is the number ownership actually needs.
  3. A menu is a portfolio, not a wish list. Every item on it is either earning its shelf space in volume, margin, or strategic reason (a loss-leader that pulls covers) — anything earning none of the three is costing the kitchen prep labor and inventory carrying cost for no return, and stays on the menu only because nobody ran the numbers.
  4. The temperature danger zone is not a suggestion with a compliance officer attached — it is the one failure mode that ends the business. Every other mistake in the kitchen costs money or a bad review; a foodborne-illness outbreak closes the doors. This is the only line item where "good enough most of the time" is not an acceptable standard, and it's why logs get checked before covers get counted.
  5. A vendor relationship is risk management, not a price negotiation. The cheapest purveyor who occasionally ships a bad case, misses a Friday delivery, or can't be reached at 6am on a Saturday costs far more in a single bad week than a price difference of a few points ever saved — vetting for reliability and recourse matters as much as vetting for cost.

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.
