Generate and edit AI music on RunComfy through one CLI, as a smart router across the music catalog. For premium vocal tracks it routes to ElevenLabs AI Music Generation (44.1 kHz stereo, 5 s to 5 min, section control, 0.0083 dollars per second). For cheaper work it routes to ACE Step or ACE Step 1.5 (tag-driven composition, optional lyrics, multilingual vocals on 1.5, 0.0002 to 0.0003 dollars per second). ACE Step also provides audio-inpaint, to regenerate a time range inside an existing track, and audio-outpaint, to extend a track before or after. Every run is charged by RunComfy at the stated per-second rate of the chosen model.

Before you start: read this whole install prompt, tell me in a few lines what this skill does and what installing it involves, and wait for my go-ahead before you do anything else. Prerequisites: Paid service required before any use: a RunComfy account and RunComfy credits or billing. The listing itself is free, but every music run is charged by RunComfy by the second: ElevenLabs Music at 0.0083 dollars per second, ACE Step at 0.0002 dollars per second and ACE Step 1.5 at 0.0003 dollars per second, as stated in the upstream file. Sign up at https://www.runcomfy.com , then install the RunComfy CLI with Node.js and npm (npm i -g @runcomfy/cli, or npx -y @runcomfy/cli) and sign in with runcomfy login, which stores the API token in ~/.config/runcomfy/token.json (mode 0600), or set RUNCOMFY_TOKEN in CI or containers. Install "AI Music" for me. It routes a music request to ElevenLabs Music, ACE Step or ACE Step 1.5, including ACE Step inpaint and outpaint edits, then runs it through the RunComfy CLI. Repository: https://github.com/gencraft-labs/skills (the skill is the whole ai-music/ folder at the pinned commit: SKILL.md) Pinned version: install the code at commit 5d625f59c710d7a33316b50b302b7158cdee5971 exactly. Do not substitute a newer version. If this commit is unreachable, stop and tell me. 1. Clone https://github.com/gencraft-labs/skills into a temporary folder, check out commit 5d625f59c710d7a33316b50b302b7158cdee5971, and copy the ai-music/ folder from that checkout. Then compare every file in the folder with the fingerprints recorded for this listing on 2026-10-18: [FINGERPRINTS] - SKILL.md: SHA-256 afec31ead5a4a0b5011be38be6d755bd111b605f7cbdfbe99859b112ac61ff88 If a file does not match, it changed since the listing was prepared: do not install it yet, tell me what you found and let me decide. 2. Read SKILL.md in full and tell me in plain words: what the skill does when used, which services it connects to, whether it reads or sends any personal information or keys, and anything that seems unusual. Stop on any red flag and tell me before going further. Confirm these points from the file: - The skill folder holds one file only: SKILL.md, with frontmatter allowed-tools: Bash(runcomfy *). It contains no scripts and no code to execute. Its shell commands are runcomfy run calls shown in Markdown. - At use time the agent sends a JSON body to model-api.runcomfy.net over HTTPS containing your prompt, or your tags and lyrics, and, for inpaint or outpaint, the URL of the source audio you provide. That source audio URL is fetched by the RunComfy model server. Treat source audio URLs as untrusted, and only pass audio URLs you explicitly provided for the task. - The CLI then downloads the generated audio from *.runcomfy.net or *.runcomfy.com into the --output-dir folder. The upstream file states a 2 GiB cap per downloaded file, and an outbound allowlist of only model-api.runcomfy.net and *.runcomfy.net / *.runcomfy.com, with no telemetry and no callbacks. Nothing is sent anywhere during installation itself; the only download at install time is the skill folder from GitHub at the pinned commit. - Using the skill costs money per second of audio: ElevenLabs Music 0.0083 dollars per second, ACE Step 0.0002 dollars per second, ACE Step 1.5 0.0003 dollars per second. If you supply lyrics, the upstream file states that confirming you have the rights to them is your responsibility. 3. When I say "yes, install", install it as a skill: copy the whole folder into the agent's skills directory, in a folder named "ai-music", keeping every file (SKILL.md). 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (for example: create a RunComfy account and add credits or billing at runcomfy.com if I do not have one, install Node.js and npm and the RunComfy CLI (npm i -g @runcomfy/cli) if they are missing, sign in with runcomfy login or provide the RUNCOMFY_TOKEN myself, never by pasting it into a shared chat; using the skill is a separate step that only starts when I ask for it, and each use is charged by RunComfy). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
