Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

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

The skill explicitly instructs the agent to fetch and read external component documentation and example URLs (e.g., "Run npx shadcn@latest docs <component>" and the `add`/`view` commands which accept arbitrary registry URLs, plus the MCP "view_items_in_registries" tool), meaning untrusted public registry/GitHub/raw docs are ingested and can directly influence install, merge, and update actions.

Low

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 explicitly instructs the agent at runtime to fetch component docs/examples (e.g. the example URL pattern https://raw.githubusercontent.com/... referenced by `npx shadcn@latest docs` and "Fetch these URLs to get the actual content") and to use that fetched content to drive how the agent composes/edits code, meaning remote content can directly control agent instructions.
