acestepAI music generation with ACE-Step 1.5 — background music, vocal tracks, covers, stem extraction for video production.
Acestep is an agent skill from calesthio/OpenMontage. AI music generation with ACE-Step 1.5 — background music, vocal tracks, covers, stem extraction for video production. Use when generating music, soundtracks, jingles, or working with audio stems. Triggers include background music, soundtrack, jingle, music generation, stem extraction, cover, style transfer, or musical composition tasks.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Music and audio generation and Video production. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is AGPL-3.0.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9327439. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
RUNPOD_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Acestep loads about 2.3k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 737 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
EY` and `RUNPOD_ACESTEP_ENDPOINT_ID` in `.env` (run `--setup` to create endpoint).Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

[Verse 1]
Walking through the morning light
Coffee in my hand feels right
Another day to build and dream
Nothing's ever what it seems
[Chorus - anthemic]
WE KEEP MOVING FORWARD
Through the noise and doubt
We keep moving forward
That's what it's about
[Verse 2]
Screens are glowing late at night
Shipping code until it's right
The deadline's close but so are we
Almost there, just wait and see
[Chorus - bigger]
WE KEEP MOVING FORWARD
Through the noise and doubt
We keep moving forward
That's what it's about
[Outro - fade]

AI music generation with ACE-Step 1.5 — background music, vocal tracks, covers, stem extraction for video production. Acestep is an agent skill from calesthio/OpenMontage.5 — background music, vocal tracks, covers, stem extraction for video production.
Acestep fits situations like: generating music; working with audio stems; include background music; music generation.
Run `npx skills add calesthio/OpenMontage --skill acestep -a claude-code`. Or copy the skill folder (.agents/skills/acestep in calesthio/OpenMontage) into .claude/skills/acestep in your project. Claude Code loads it when a task matches its description.
Run `npx skills add calesthio/OpenMontage --skill acestep -a codex`. Or copy the skill folder (.agents/skills/acestep in calesthio/OpenMontage) into .agents/skills/acestep in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add calesthio/OpenMontage --skill acestep -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/acestep, .gemini/skills/acestep, .github/skills/acestep and .opencode/skills/acestep in your project.
Going by SKILL.md and its folder, Acestep needs the command-line tools its instructions call (python) and credentials named RUNPOD_API_KEY. Our summary lists: Python 3; A credential in RUNPOD_API_KEY.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Acestep is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Acestep: Music to Video (heygen-com/hyperframes, 59k stars), Paper Collage Explainer Generator (tl2012tl/comfyUI-llama-TE, 241 stars), Short Form Edit (nateherkai/hyperframes-student-kit, 1.2k stars) and Tesseract Video (mirage-hq/Tesseract, 128 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
