AF skill-auditor-plus
Security, performance, and quality auditing for AgentSkills. Use when reviewing skills before installation, auditing during development, checking installed skills for risks, optimizing performance, or ensuring best practices compliance. Automated scanning for dangerous operations, credential leaks, token bloat, and quality issues.
As a process F 38/100 · Will not run — References files that are not bundled: references/feature-name.md
How to improve
- The text references files that are not there: add them or drop the references.
- 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-refreference to a missing file: references/feature-name.md
Process rating: all ten parameters 38/100
- 0Tools and files. 1 referenced file(s) missing: references/feature-name.md
- 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. 1 mutating operations with no state check
- 50Failures and branches. 0 branches, has a failure section
- 100Steps. 43 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1707 tokens
- 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.
