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.

  • warning missing-ref reference to a missing file: scripts/overlay.py

Process rating: all ten parameters 38/100

Will not run. References files that are not bundled: scripts/overlay.py
  • 0Tools and files. 1 referenced file(s) missing: scripts/overlay.py
  • 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
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 2 mutating operations with no state check
  • 50Failures and branches. 0 branches, has a failure section
  • 100Steps. 20 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 1325 tokens

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.

External checks

ClawHub: suspicious
This skill is a coherent demo-video generator, but it needs review because it makes broad system changes and uses unsafe shell command construction around user-customized demo text.
