Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
SKILL.md requires installing and then “reading the full SKILL.md before using it” for skills downloaded from outsider sources like ClawHub/GitHub/Hermes hubs, which means outsider-authored Markdown from downloaded skill directories becomes LLM-readable prompt context at runtime.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The SKILL explicitly shows runtime download/install commands (git clone, curl, letta skills install) that fetch SKILL.md or repository content from external URLs (e.g., https://github.com/NousResearch/hermes-agent.git and https://github.com/anthropics/skills), and that fetched content can contain markdown prompting instructions or scripts that execute code, so these URLs are runtime dependencies that can control prompts or run code.
