sync-gbrain
Keep gbrain current with this repo's code and refresh agent search guidance in CLAUDE.md. Wraps the gstack-gbrain-sync orchestrator with state probing, native code-surface registration, capability checks, and a verdict block. Re-runnable, idempotent. Use when: "sync gbrain", "refresh gbrain", "re-index this repo", "gbrain search isn't finding things". (gstack)

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). This skill explicitly fetches and merges remote repo data (git fetch/merge in the ~/.gstack repo), reads a brain-remote URL (~/.gstack-brain-remote.txt) and runs the gbrain CLI (put/search/sources list) to read page_counts and search results, and then uses those remote/user-generated artifacts to decide whether to reindex, update CLAUDE.md, or change sync behavior—i.e., it ingests untrusted third-party repo/brain content that can materially influence subsequent actions.
