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 explicitly requires a DOC_SOURCE_URL and instructs the generated script to download, extract, and process upstream documentation archives (e.g., GitHub/GitLab/direct archive links) — see "Download & Extract" in references/doc-updater-template.md and Phase 4's validation where random markdown files are read — so arbitrary public third‑party content is ingested and can influence agent behavior.

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: 0.80). The skill downloads and ingests the user-supplied DOC_SOURCE_URL at runtime (e.g., https://gitlab.com/gitlab-org/cli/-/archive/main/cli-main.tar.gz?path=docs), which will be processed into markdown context consumed by agents and thus can directly control prompts/instructions from remote content.
