BB Cooking
Cooks and rescues real dishes at the stove: heat control, seasoning, doneness, timing, substitutions, and food safety. Use when a dish is bland, too salty, burnt, tough, dry, watery, rubbery, greasy, or gummy; when a sauce breaks, splits, curdles, or will not thicken; when meat, fish, eggs, rice, pasta, beans, bread, or a cake come out wrong; when adapting a recipe for a missing ingredient, a different pan, an air fryer, altitude, or a doubled batch; when asking what temperature something is done at, how long to rest it, how much salt, or whether leftovers are still safe; when searing, braising, roasting, frying, grilling, baking, fermenting, or curing; or when ordering the work so a whole meal lands hot at once. Not for weekly menus and shopping lists (`meal-planner`, `grocery`), recipe collections and recipe walkthroughs (`recipe`, `chef`), calorie or macro counting (`calories`), or micronutrients (`nutrition`).

What is at stake
The skill contains fragments that, in the wrong hands, cost money or data. Below: what the installer risks and what the author should do.
The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".
If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.
How to improve
- Address the high-severity findings: each costs 18 safety points. If one is a false positive, add the rule id to guard.allow in spec.yaml.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 70/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 8 mutating operations with no state check
- 60Tools and files. Uses tools (bash, read) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70Execution cost. Instruction body is 7454 tokens
- 100Steps. 43 steps
- 100When it triggers. States when to use and when not to
- 100Failures and branches. 5 branches, has a failure section
- 100Consistency. Name and required fields are in place
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 12 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
