setup-gbrain
Set up gbrain for this coding agent: install the CLI, initialize a local PGLite or Supabase brain, register MCP, capture per-remote trust policy. One command from zero to "gbrain is running, and this agent can call it." Use when: "setup gbrain", "connect gbrain", "start gbrain", "install gbrain", "configure gbrain for this machine". (gstack)

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: 0.90). The skill explicitly fetches user transcripts and gbrain search results into the model preamble at runtime (via gbrain using the GBRAIN_DATABASE_URL / Supabase Session Pooler URL obtained from https://supabase.com/dashboard and it also calls the Supabase API e.g. https://api.supabase.com/v1/projects), which means externally-hosted content is pulled at runtime and injected into the agent context — directly controlling prompts; this meets the flag criteria.
