3 findings — 3 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: 0.90). The SKILL.md explicitly pulls code from public git_repo sources (e.g., "sources: - kind: git_repo url: github:<org>/<repo>.git") and its install-commands run %{make}/%{make-install} and use jq to read metadata.json from those repos to determine UUIDs and extraction paths, so untrusted third-party repository content is fetched and directly influences build/install 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 declares git_repo sources like "url: github:<org>/<repo>.git" which are fetched at build/runtime and whose upstream code (make/meson scripts) will be executed as part of the install/build steps, enabling remote code execution from those repositories.
W013: Attempt to modify system services in skill instructions
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
Attempt to modify system services in skill instructions detected (high risk: 0.90). The prompt instructs copying/moving files into system locations like /usr/share and glib-2.0/schemas and running commands that modify system-installed schemas (e.g., glib-compile-schemas), which are actions that normally require elevated privileges and can change the host system state.
