Music Cog - Original Music, Fully Yours

Music generation — 5 seconds to 10 minutes. Instrumental and vocal tracks with high-quality AI vocals.

Generated tracks are royalty-free for commercial use per CellCog's terms of service — YouTube, podcasts, apps, games, ads, films, streaming.

How to Use

For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.

OpenClaw (fire-and-forget):

result = client.create_chat(
    prompt="[your task prompt]",
    notify_session_key="agent:main:main",
    task_label="my-task",
    chat_mode="agent",
)

All agents except OpenClaw (blocks until done):

from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])

Two Ways to Create Music

Simple Prompt (Use This 99% of the Time)

Just describe what you want. The model handles the rest — genre, arrangement, instrumentation, dynamics, and even lyrics:

"Compose a 90-second cinematic score. Start with solo piano, layer in strings at 30 seconds, build to a full orchestral swell, then resolve softly. Mood: bittersweet turning hopeful."

"Create a 3-minute lo-fi hip-hop track with soft piano, vinyl crackle, and mellow drums. 75 BPM. Study vibes."

"Write a 2-minute upbeat pop song with female vocals about starting fresh on a Monday morning. Catchy chorus, feel-good energy."

The model is exceptionally sophisticated — it handles any genre, genre fusion, songs with lyrics, complex arrangements, and mood transitions from a simple description.

Composition Plan (For Precise Timing Control)

Only use this when you need exact section durations — for example, syncing music to specific video segments or presentation slides:

"I need music that syncs with my video:

  • Intro: exactly 10 seconds, soft ambient
  • Build: exactly 20 seconds, energy rising
  • Climax: exactly 15 seconds, full orchestra
  • Outro: exactly 10 seconds, gentle fade"

This mode gives precise timing control per section but should only be used when timing accuracy matters for syncing with other media.


What Music You Can Create

Instrumental

Type Example
Cinematic scores Epic orchestral, tense thriller, emotional piano, sci-fi ambient
Background tracks Lo-fi beats, corporate background, cafe jazz, ambient soundscapes
Podcast intros/outros 5-10 second branded stings, transitions, bumpers
Game soundtracks Battle themes, exploration music, boss fights, menu themes
Jingles Ad jingles, notification sounds, reveal stingers
Ambient Meditation, nature soundscapes, focus music

Vocal Tracks

CellCog generates songs with perfect AI vocals — just describe the lyrical theme:

Type Example
Pop songs Catchy hooks, verse-chorus structure, radio-ready
Ballads Emotional, piano-driven, storytelling
Hip-hop/Rap Rhythmic vocals, beats, flow
Rock Guitar-driven, powerful vocals
R&B/Soul Smooth, melodic, groove

Specs

Parameter Range
Duration 5 seconds to 10 minutes
Output MP3 (44.1kHz, 128kbps)
Vocals Instrumental or with AI vocals
Licensing Royalty-free per CellCog terms of service

Chat Mode

Use chat_mode="agent" for music generation. Music executes well in agent mode.


Example Prompts

Cinematic score:

"Compose a 2-minute cinematic score for a nature documentary finale. Begin with solo cello (melancholic), layer in strings and piano at 40 seconds, build to a hopeful orchestral swell, resolve with gentle piano. Think Planet Earth meets Interstellar."

Lo-fi background:

"Create 5 minutes of lo-fi study beats. Soft piano, mellow drums, vinyl crackle, gentle bass. 75 BPM. Warm and unobtrusive — good for focus."

Podcast intro + outro:

"Create a podcast intro (8 seconds) and outro (6 seconds). Show is a tech startup podcast. Intro: energetic, modern electronic with a hook. Outro: same vibe but mellower wind-down. Should feel like the same show."

Song with vocals:

"Write a 3-minute upbeat indie pop song with female vocals. Theme: the excitement of moving to a new city. Catchy chorus, acoustic guitar foundation, builds with drums and synth. Feel-good, sing-along energy."

Game soundtrack:

"Compose a 2-minute boss battle theme for a fantasy RPG. Intense orchestral with choir, driving percussion, escalating tension. Think Dark Souls meets Final Fantasy."


Tips

  1. Describe the feeling, not just the genre: "Music that makes a startup pitch feel like the future" works better than "electronic music."

  2. Specify duration: "45 seconds" vs "3 minutes" changes composition structure significantly.

  3. Reference moods, not copyrighted songs: "Hans Zimmer-style epic" and "ChilledCow lo-fi vibes" work well. Do not reference specific copyrighted songs.

  4. For vocals: Set the lyrical theme and mood. The model writes lyrics that fit. Or provide specific lyrics you want sung.

  5. Energy arc matters: "Starts quiet, builds at midpoint, resolves softly" gives clear compositional structure.

  6. For video background music: If the music is for a CellCog video, mention it in your video prompt instead — CellCog handles music as part of video production automatically.


If CellCog is not installed

Run /cellcog-setup (or /cellcog:cellcog-setup depending on your tool) to install and authenticate. OpenClaw users: Run clawhub install cellcog instead. Manual setup: pip install -U cellcog and set CELLCOG_API_KEY. See the cellcog skill for SDK reference.

Usage Guidance
This skill appears to be what it says: a CellCog-backed music generator. Before installing, confirm you trust CellCog and understand their terms/privacy (generated audio and any uploaded prompts will go to their service). Provide a CELLCOG_API_KEY with least-privilege and monitor usage/billing. Note the skill lists a 'cellcog' dependency but provides no install steps — ensure the runtime environment already has the SDK or be prepared for the agent to attempt package installation. Avoid sending sensitive or private data (lyrics or transcripts containing secrets) to the service, and rotate the API key if you stop using the skill.
Capability Analysis
Type: OpenClaw Skill Name: music-cog Version: 1.0.10 The music-cog skill bundle is a standard integration for the CellCog AI music generation service. The SKILL.md file provides legitimate documentation, usage examples, and configuration instructions for an AI agent to generate audio tracks. There is no evidence of malicious intent, data exfiltration, or harmful prompt injection; the required environment variable (CELLCOG_API_KEY) and dependencies (cellcog) are consistent with the stated purpose of the tool.
Capability Tags
requires-sensitive-credentials
Capability Assessment
Purpose & Capability
Name/description match the requested resources: python3 and CELLCOG_API_KEY are expected for a Python SDK client talking to the CellCog service. Declared dependency 'cellcog' is consistent with a CellCog SDK.
Instruction Scope
SKILL.md instructs the agent to call the CellCog client API (create_chat) and to provide music prompts; it does not direct reading unrelated system files, broad data collection, or exfiltration to unexpected endpoints.
Install Mechanism
This is instruction-only (no install spec), which is low risk. Minor inconsistency: dependencies list 'cellcog' but there are no install instructions (e.g., pip). That likely means the environment must already provide the package or the agent will attempt to install it at runtime.
Credentials
Only CELLCOG_API_KEY is required — appropriate and proportional for a third-party music generation API. No unrelated secrets or broad system credentials are requested.
Persistence & Privilege
always is false and there are no claims of modifying other skills or system-wide settings. The skill can be invoked autonomously by the agent (default), which is normal for skills of this type.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install music-cog
  3. After installation, invoke the skill by name or use /music-cog
  4. Provide required inputs per the skill's parameter spec and get structured output
