Full Analysis
  • [COMMAND_EXECUTION]: The skill is configured to use the runcomfy CLI tool for music generation, inpainting, and outpainting tasks. This execution is scoped via the allowed-tools metadata field, which is a recognized security best practice for limiting agent capabilities.
  • [EXTERNAL_DOWNLOADS]: The documentation provides instructions for installing the @runcomfy/cli package from the official NPM registry. These references target the official resources of the RunComfy service and do not involve unauthorized or suspicious third-party sources.
  • [PROMPT_INJECTION]: The skill presents an indirect prompt injection attack surface because it processes untrusted data from external audio URLs during inpainting and outpainting operations.
  • Ingestion points: The audio input parameter in the acestep-ai/ace-step/audio-inpaint and acestep-ai/ace-step/audio-outpaint endpoints (SKILL.md).
  • Boundary markers: Not present in the command templates; however, the skill's documentation includes a specific security warning regarding the use of untrusted audio sources.
  • Capability inventory: Uses the runcomfy CLI to perform audio processing and remote API calls.
  • Sanitization: No specific sanitization or validation of the remote audio content is described before processing.
