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 the runtime **browse tool** when it fetches and renders **public web docs/pages** (docs/landing pages, error pages, community links) as readable prose for the agent to analyze and screenshot.
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 path (run at NEEDS_SETUP) downloads and executes a remote installer via curl -fsSL "https://bun.sh/install" and then runs it with bash, which is a runtime fetch that executes remote code and is required for the skill's build/setup.
