Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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 installer skill ingests only provider-local workspace folder contents (SKILL.md and bundled files) when importing a GitHub folder via the runtime endpoints `POST /api/v1/workspaces/{workspaceId}/skills/import-github`, and does not describe a workflow that processes arbitrary outsider-authored free text without first selecting a specific GitHub-supplied item.
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 installer explicitly accepts and fetches GitHub content at runtime (e.g., "github.com/anthropics/skills" and patterns like "github.com/<owner>/<repo>/tree/<ref>/<path>" and ".../blob/<ref>/<path>/SKILL.md"), which will be retrieved and written into the workspace and can directly control skill prompts/instructions, so this is a runtime external dependency that controls agent behavior.
