As a process F 45/100 · Will not run — References files that are not bundled: url
How to improve
- 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.

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.

ClawHub: suspicious
This email-sending skill mostly matches its purpose, but it asks for email credentials in chat and defaults to a shared sender account without asking the user first.
