2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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.
Third-party content exposure detected (high risk: 0.90). The skill explicitly allows importing skills from arbitrary URLs ("/skill setup" → Quick Actions → Option 4: Import skill — "URL: Download skill from a URL (e.g., GitHub gist)"), which ingests untrusted third‑party/user‑generated markdown that the agent will validate, save to local skills and can be auto-applied (per "Automatic Application"), so remote content can materially influence agent behavior.
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.
Potentially malicious external URL detected (high risk: 0.90). The interactive Import Skill option in /skill setup explicitly downloads a skill from a user-provided URL (e.g., a GitHub Gist URL such as https://gist.github.com/<id>), and the fetched markdown would be saved as a local skill that can directly control agent prompts/instructions at runtime.
