AC win-cleaner
Deep clean Windows C drive junk files to maximize free space. Analyzes disk usage, identifies safe-to-delete items, and cleans caches, temp files, logs, browser data, application caches, Windows Store, .NET, game, and video-conferencing caches while protecting user data and system stability. Use whenever the user asks to clean C drive, free up disk space, remove junk files, optimize Windows storage, or when C drive is full or running low.
As a process C 57/100 · Has gaps — weak spots: result and completion, inputs and preconditions, execution cost
How to improve
- 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.

Against the Agent Skills spec
- warning
body-longSKILL.md body ≈ 17017 tokens (recommended < 5000); move details to references/
Process rating: all ten parameters 57/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 10Execution cost. Instruction body is 17017 tokens: crowds the task out of the window
- 30Running it twice. 16 mutating operations with no state check
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 70Failures and branches. 6 branches
- 100Steps. 40 steps
- 100When it triggers. States when to use and when not to
- 100Consistency. Name and required fields are in place
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 10 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.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
