Fix and improve this skill with Tessl
tessl review fix ./examples/skills/diagnose/SKILL.mdW011: 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
The skill fetches an external knowledge base and executes an external script from GitHub via curl without user selection of specific items, allowing potential third-party content injection.
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 fetches and executes an arbitrary remote audit script and pulls instructions from an unofficial GitHub repository at runtime, presenting a weak/unknown third-party operational dependency.
