The Agent Skills Directory

[COMMAND_EXECUTION]: The skill documents and tests a CLI tool (supertonic). While tests/test_cli.py uses subprocess.run(), these are standard smoke tests for validating that the CLI responds correctly to --help, version, and list-voices commands.
[EXTERNAL_DOWNLOADS]: The skill downloads an ONNX model (~260MB) from Hugging Face during its first run. This is a documented and standard operation for modern local-inference AI tools. The source is the official repository for Supertone-inc on Hugging Face.
[SAFE]: All external dependencies (such as onnxruntime and soundfile) and installation instructions (via pip or uv) target official package registries and well-known developer platforms.
