2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.75). The skill uses the browse daemon to fetch live production pages at runtime (`$B goto <url>` / `$B links` / `$B text` / `$B snapshot`), and the extracted page text and link content can include outsider-authored free text that is ingested into the agent’s LLM context for analysis and alerting.
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
Potentially malicious external URL detected (high risk: 0.90). The skill's setup step (when bun is missing) downloads and executes the Bun installer at runtime via curl -fsSL "https://bun.sh/install" and then runs it, which fetches and executes remote code (https://bun.sh/install).
