Security checks for external content — downloads, fetched documents, attachments, and newly imported resources. Use when verifying external content before trusting it. External information is never trusted until evidence confirms it cannot harm the system.

How to improve
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- 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.

- low 27 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.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +1No license
- +2Single-language instructions
- +3Description length 256: enough signal without eating the budget
- +4Structure: 87 headings
- +3Step-by-step instructions: 282 items
- +3Output format is stated explicitly
- +4Has examples (2 code blocks)
- +4Reference files are cited in the instructions (1 of 5)
Quality base 70; lint remarks subtract, signals add up to 100. Result: 75.

ClawHub: clean
This skill is a security guidance document that mostly tells the agent to sandbox, verify, and ask before risky actions; the remaining issues are documentation caveats rather than hidden harmful behavior.
