Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.02680 |
| Opus 5.5 | $0.00024 | $0.01072 |
| Sonnet 5.5 | $0.00012 | $0.00536 |
| Haiku 4.5 | $0.00006 | $0.00268 |
Grade B, and why
ace-step-music-generation-remix scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- **Linux**: `sudo apt-get install jq` (Debian/Ubuntu) or `sudo dnf install jq` (Fedora) Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
The `scripts/acestep.sh` script requires: **curl** and **jq**. Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ACE-Step Music Generation Skill
Use ACE-Step V1.5 API for music generation. Always use scripts/acestep.sh script — do NOT call API endpoints directly.
Quick Start
# 1. cd to this skill's directory
cd {project_root}/{.claude or .codex}/skills/acestep/
# 2. Check API service health
./scripts/acestep.sh health
# 3. Generate with lyrics (recommended)
./scripts/acestep.sh generate -c "pop, female vocal, piano" -l "[Verse] Your lyrics here..." --duration 120 --language zh
# 4. Output saved to: {project_root}/acestep_output/
Workflow
For user requests requiring vocals:
- Use the acestep-songwriting skill for lyrics writing, caption creation, duration/BPM/key selection
- Write complete, well-structured lyrics yourself based on the songwriting guide
- Generate using Caption mode with
-cand-lparameters
Only use Simple/Random mode (-d or random) for quick inspiration or instrumental exploration.
If the user needs a simple music video, use the acestep-simplemv skill to render one with waveform visualization and synced lyrics.
MV Production Requirements: Making a simple MV requires three additional skills to be installed:
- acestep-songwriting — for writing lyrics and planning song structure
- acestep-lyrics-transcription — for transcribing audio to timestamped lyrics (LRC)
- acestep-simplemv — for rendering the final music video
Script Commands
CRITICAL - Complete Lyrics Input: When providing lyrics via the -l parameter, you MUST pass ALL lyrics content WITHOUT any omission:
- If user provides lyrics, pass the ENTIRE text they give you
- If you generate lyrics yourself, pass the COMPLETE lyrics you created
- NEVER truncate, shorten, or pass only partial lyrics
- Missing lyrics will result in incomplete or incoherent songs
Music Parameters: Use the acestep-songwriting skill for guidance on duration, BPM, key scale, and time signature.
# need to cd to this skill's directory first
cd {project_root}/{.claude or .codex}/skills/acestep/
# Caption mode - RECOMMENDED: Write lyrics first, then generate
./scripts/acestep.sh generate -c "Electronic pop, energetic synths" -l "[Verse] Your complete lyrics
[Chorus] Full chorus here..." --duration 120 --bpm 128
# Instrumental only
./scripts/acestep.sh generate "Jazz with saxophone"
# Quick exploration (Simple/Random mode)
./scripts/acestep.sh generate -d "A cheerful song about spring"
./scripts/acestep.sh random
# Options
./scripts/acestep.sh generate "Rock" --duration 60 --batch 2
./scripts/acestep.sh generate "EDM" --no-thinking # Faster
# Other commands

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ace-step-music-generation-remix is a skill published in the GitHub repository rondoflow/rondoflow (25 stars, last pushed 6d ago), licensed MIT. It adds 61 tokens to every session and 2,680 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
takt
A workflow engine that runs a task through a sequence of steps defined in a YAML file, using separate coding agents for the work.
codebase-context-extractor
This skill provides a comprehensive context extraction system for large codebases. It intelligently analyzes code structure, dependencies, and relationships to extract relevant context for understanding, debugging, or modifying code.
dos-dispatch
Plan and ship the next batch on one lane: run dos-next-up, acquire a lease with dos arbitrate, gate empty work, dispatch the packet, and archive the run. Use when a single lane should move end to end with collision safety.
dos-enforce-tune
Tune DOS enforcement policy knobs ([interventionpolicy], [intervention], [improve]) from false-deny versus held-catch evidence. Use when running dos enforce-tune to keep only measured nettaskdelta gains and escalate repeated non-keeps.
dos-class-cycle
Run one DOS plan-class lifecycle tick from the workspace [lifecycle] table: evaluate declared transitions, have a judge approve/defer them, write gated plan-meta edits, and log the cycle. Use when gardening plan lifecycle classes automatically.
dos-verify-done-claims
Before accepting an agent's 'done / shipped / fixed' claim, verify it against ground truth (git ancestry + the commit's own diff) using the DOS kernel's dos verify and dos commit-audit — never the agent's own narration.
