Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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.
The skill’s required runtime workflow ingests only first-party search results metadata via `search_skills(query)` and installs a specific third-party skill only after explicit user install intent (`install_skill(install_source)`), but it does not read arbitrary outsider-authored free text without actively selecting/fetching a specific item.
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.
The skill shows a runtime call to install_skill("claude-plugins:vercel-labs/agent-skills/skills/react-best-practices") (SKILL.md:109) which will fetch and install third‑party code that runs with full agent permissions, so external content is retrieved at runtime and can execute.
