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 scans and reads SKILL.md files in the repo's .claude/skills directory (Phase 8 Tier 1) and — with user approval — globally installed skills (Phase 8 Tier 2), and its GBrain Sync step can git-fetch/merge a remote "brain" repo into local context; these are untrusted/user-generated inputs the agent ingests as part of its workflow and can materially influence searches, reasoning, or tool choices, creating a clear indirect prompt-injection vector.
