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: 0.80). The SKILL.md explicitly instructs the agent to clone/fork and read external skill repositories and even auto-install a plugin from GitHub (e.g., "claude plugin marketplace add https://github.com/daymade/claude-code-skills" and "Clone repository to /tmp/" in the Review/Auto-PR workflows), which requires ingesting untrusted public third‑party content that can influence subsequent review/edit/PR actions.
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 auto-install sequence adds and installs a plugin from https://github.com/daymade/claude-code-skills and then runs python scripts from the installed skill-creator (e.g., quick_validate.py), which fetches and executes remote code at runtime and is presented as a required dependency for validation.
