1 high severity finding. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill asks the user for database connection strings, OAuth client secrets, access tokens, and service-role keys and shows them being embedded verbatim into CLI commands and config files (e.g., --url "<connection_string>", --oauth-client-secret <secret>, SUPABASE_ACCESS_TOKEN, serviceRoleKey), which requires the LLM to handle/output secrets directly and creates exfiltration risk.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The skill's install step runs "bun install -g github:garrytan/gbrain#latest-stable", which fetches and installs remote code from the GitHub repo at runtime (github:garrytan/gbrain#latest-stable), satisfying the criteria for executing external code during setup.
