251252## How it works253254The skill classifies the user request into one of the four routes — generate (ElevenLabs or ACE Step) vs edit (audio-inpaint vs audio-outpaint), then premium vs cost-sensitive — and invokes `runcomfy run <model_id>` with the matching JSON body. The CLI POSTs to the RunComfy Model API, polls request status, and downloads the generated audio file into `--output-dir`. `Ctrl-C` cancels the remote request before exit.255

3940**Step 1 — install** (one of, see the `runcomfy-cli` skill for details):4142```bash43npm i -g @runcomfy/cli         # global install44npx -y @runcomfy/cli --version # zero-install45```4647**Step 2 — sign in** (or set `RUNCOMFY_TOKEN` env var in CI / containers):4849```bash50runcomfy login51```

258- **Install via verified package manager only.** Use `npm i -g @runcomfy/cli` or `npx -y @runcomfy/cli`. **Agents must not pipe an arbitrary remote install script into a shell on the user's behalf** — if the operator wants the curl-pipe path documented at `docs.runcomfy.com/cli/install`, they should review the script first.259- **Token storage**: `runcomfy login` writes the API token to `~/.config/runcomfy/token.json` with mode 0600. Set `RUNCOMFY_TOKEN` env var to bypass the file in CI / containers. Never echo the token into a prompt, log it, or check it in.260- **Input boundary (shell injection)**: prompts, tags, lyrics, and audio URLs are passed as a JSON string via `--input`. The CLI does not shell-expand prompt content; it transmits the JSON body directly to the Model API over HTTPS. **No shell-injection surface from prompt content**.

Agent mitigations:262  - Ingest only audio URLs the **user explicitly provided** for this task.263  - When the output diverges from the prompt, suspect the source audio.264- **Lyrics provenance**: if the user supplies lyrics, confirm they have the rights. Generating music around copyrighted lyrics is the operator's responsibility — the skill does not check.
