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.

Against the Agent Skills spec

  • warning missing-ref reference to a missing file: references/devtools-api.md

Process rating: all ten parameters 54/100

Will not run. References files that are not bundled: references/devtools-api.md
  • 0Tools and files. 1 referenced file(s) missing: references/devtools-api.md
  • 20When it triggers. No condition that starts the skill
  • 40Consistency. Frontmatter name (browser-devtools-inspector) differs from the folder (qtada-browser-devtools-inspector)
  • 50Failures and branches. 0 branches, has a failure section
  • 60Result and completion. Output format stated, no completion criterion
  • 70Inputs and preconditions. Inputs and preconditions are listed
  • 100Steps. 15 steps
  • 100Execution cost. Instruction body is 1548 tokens
  • 100Running it twice. No mutating operations
  • 100Progress reporting. Reports progress

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.
