AC JavaScript
A comprehensive JavaScript style guide skill. When activated, it provides best-practice JavaScript coding conventions and generates code that strictly follows the style guide, covering variables, functions, objects, arrays, classes, modules, async patterns, error handling, naming conventions, and more.
As a process C 61/100 · Has gaps — weak spots: result and completion, inputs and preconditions, consistency
How to improve
- 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.

Against the Agent Skills spec
- warning
name-formatname should be kebab-case (lowercase letters, digits, hyphens)
Process rating: all ten parameters 61/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 2 mutating operations with no state check
- 40Consistency. Frontmatter name (JavaScript) differs from the folder (javascript-skills)
- 70Failures and branches. 5 branches
- 70Execution cost. Instruction body is 4313 tokens
- 100Tools and files. No external tools needed
- 100Steps. 127 steps
- 100When it triggers. States when to use and when not to
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
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.
