The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill references a Node.js setup script from NodeSource, a well-known service for Node.js distribution, during the Docker build process.
[COMMAND_EXECUTION]: The workflow involves executing standard build and deployment commands such as mix, docker build, and docker run to manage the Phoenix application lifecycle.
[CREDENTIALS_UNSAFE]: The skill correctly instructs the use of environment variables (DATABASE_URL, SECRET_KEY_BASE) for managing sensitive configuration, which is a standard security practice for containerized applications.
[INDIRECT_PROMPT_INJECTION]: The skill processes project-specific files during the release generation phase, which represents a potential injection surface.
Ingestion points: mix phx.gen.release reads local application files (mix.exs, config/*.exs).
Boundary markers: None explicitly defined in the generated templates.
Capability inventory: Execution of mix and docker CLI tools.
Sanitization: Relies on the default behavior of the Phoenix release generator and standard Elixir tooling.
