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). Outsider free text can enter the LLM context via runtime browser-extracted page content during `$B goto/links/snapshot` in the QA phases (e.g., arbitrary target URL text, console messages, and DOM text scraped by the browse tool), which is not authored by the operating user.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 1.00). The skill's setup step conditionally runs a curl to download and then bash-executes the Bun installer at https://bun.sh/install (curl -fsSL "https://bun.sh/install" -o "$tmpfile" … bash "$tmpfile"), which fetches remote code and executes it at runtime.
