E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Several of the listed URLs point to non‑official/test hosts (example.test) and a generic GitHub releases download path that are capable of delivering archives/executables — these are higher-risk download vectors unless the consumer strictly enforces the signature+checksum verification shown in the repository.
Low
Low-risk findings.
1 low severity finding. 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 guarded advisory workflow reads outsider-authored free text from a remote/local advisory feed JSON (fetched via `globalThis.fetch` in `lib/feed.mjs` and then parsed/matched in `scripts/guarded_skill_verify.mjs` and `lib/attestation.mjs`).
