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 "CRITICAL: Assistant Workflow" Step 4 explicitly directs the assistant to perform web searches and read public action documentation for unknown public actions (e.g., "Use web search" to verify action inputs/versions), which requires fetching and interpreting untrusted third‑party web pages that can materially influence validation and subsequent 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: 1.00). The install script (scripts/install_tools.sh) fetches and executes remote installers at runtime via "curl ... https://raw.githubusercontent.com/nektos/act/master/install.sh | bash" and "bash <(curl https://raw.githubusercontent.com/rhysd/actionlint/main/scripts/download-actionlint.bash)", which runs remote code and is required for the skill to function.
