    External CLI execution submits prompts and media references to RunComfy.
    Keep the provider, command, required account, and outbound endpoint disclosure prominent before any invocation instructions.
  2. FIX-002
    Low
    Users may include private images, videos, audio, or prompts in model requests.
    Add a short privacy reminder that user-provided media URLs and prompts are processed by RunComfy and should not contain sensitive data unless approved.
