How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • 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.

Will not run. References files that are not bundled: scripts/linux/*.sh, scripts/windows/*.ps1
  • 0Tools and files. 2 referenced file(s) missing: scripts/linux/*.sh, scripts/windows/*.ps1
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 40Consistency. Frontmatter name (DirStat_Skill) differs from the folder (dirstat-skill)
  • 50When it triggers. No condition that starts the skill
  • 55Failures and branches. 1 branches
  • 60Result and completion. Output format stated, no completion criterion
  • 100Steps. 111 steps
  • 100Execution cost. Instruction body is 2050 tokens
  • 100Running it twice. No mutating operations
  • 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
  • +2Single-language instructions
  • +4Description says when NOT to use the skill
  • +3Description length 211: enough signal without eating the budget
  • +4Structure: 21 headings
  • +3Step-by-step instructions: 111 items

  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 78.

External checks

ClawHub: suspicious
The skill is a real disk-usage reporter, but it needs Review because its read-only framing includes a sudo installer that can take a password from stdin.
