The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill documents the installation of the better-auth core package and official ecosystem plugins (e.g., @better-auth/passkey, @better-auth/mcp) via standard package managers like bun. These resources are hosted on public registries and are associated with the framework's official ecosystem.
[COMMAND_EXECUTION]: The skill provides instructions for using the auth CLI tool (bunx auth@latest) to perform administrative tasks such as generating secrets, migrating database schemas, and creating admin users. These commands are part of the intended management workflow for the auth library and are documented for developer use.
[INDIRECT_PROMPT_INJECTION]: The framework described handles external data from OAuth providers and user registration. The skill includes specific guidance on mitigating mass-assignment and injection risks through schema validation and the use of the input: false property for sensitive user fields like roles.
[CREDENTIALS_UNSAFE]: The documentation references environment variables such as BETTER_AUTH_SECRET and social provider secrets. These are presented as placeholders or instructions for secure environment configuration in .env files rather than hardcoded credentials.
