image — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited image (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Base64-encodes the image and passes it to a vision-capable LLM that extracts all text and key information. Returns the LLM's response as result.text.
No pip dependency — the skill uses only the Python standard library plus a LLM provider you supply at construction time. The provider can be any object that implements the complete() interface (see below).

# ImageSkill REQUIRES a vision-capable provider — calling extract() without
# one raises ValueError immediately.

result = await skill.extract("/path/to/screenshot.png")
