AF skill-privacy-guard
STOPS all sensitive information from entering skill files. Automatically blocks usernames, paths, personal data when creating or updating skills. CRITICAL - highest priority.
As a process F 53/100 · Will not run — References files that are not bundled: ?!example
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.
