Game Music Pack Architect for Suno
One line in. A full production plan out.
Install the skill, then say "cozy farming sim, 12 tracks, I want to sell it on an asset marketplace" — and you get back the whole plan: which tracks to make, the exact Suno Styles-field text for every generation, which prompts need length protection, how to loop and master the result, and what it will cost in credits.
📦 This is a downloadable skill, not a hosted agent. You get the files and run them in your own Claude Code, Codex, OpenClaw, or Hermes — no rate limits, no metering, no account linking. It does not generate audio; it writes the plan you execute in Suno.

What comes back, every time
- Pack summary — pack code, palette, track count, target use
- Slot allocation table — how the track count splits across the eight game states, with the originals-vs-variations breakdown
- Execution table — one row per generation:
# | slot | title code | source | what varies | Styles field, the Styles field written out in full and copy-pasteable - Length-risk annex — which rows got the anti-truncation clause and the exact term that earned it
- Delivery spec — loop handling, WAV/MP3 formats, LUFS target, file naming scheme
- Credit budget — generations, buffer, expected takes
- Execution notes — Suno UI settings, batch order, what to verify after each batch
The three failures it exists to prevent
1. Truncation. Atmospheric prompts come back as 10-second fragments. There is a specific class of words that causes it and a specific phrasing that fixes it — and a near-identical phrasing that makes it worse. In a controlled comparison, one wording recovered 6 of 8 dead codes (39 s → 87–136 s) while the other returned 23–64 s on all six attempts. The skill knows which is which, and flags every prompt that needs the clause before you spend a credit on it.
2. No architecture. A "20-track pack" with no slot plan ships as 20 similar loops. Buyers map tracks to the game states they actually have — menu, exploration, combat, boss, hub, tension, stingers, ambience. The allocation tables here come from real 30-track pack shapes, not from guesswork.
3. Fake variation. Rewording a prompt returns the same music. Variations must move at least two of three axes — lead instrument, BPM, key — and the plan states which two, for every variation row.
It also carries a genre length bias table most people never discover: identical length instructions produced a mean best-take length of 171 s for one palette and 88 s for a cartoon/casual palette in the same production run. Light genres need heavier length protection and more post-production time, and the plan says so up front instead of after you have generated.
Twelve genre palettes, ready to use
Wuxia · Noir jazz · Chiptune · Cartoon/casual · Cozy life-sim · Cyberpunk · High fantasy · Horror · Pixel adventure · Racing/sports · Sci-fi · Traditional/folk
Each with lead instruments, articulations, rhythm and harmonic bed, BPM bands per slot, scale family, production tag, and its own truncation-risk warnings.
Who this is for
- Indie developers scoring their own game who need coverage, not a playlist
- Asset sellers producing packs for game-asset marketplaces
- Composers and sound designers using AI for drafts and needing a repeatable pipeline
- Anyone whose Suno loops keep coming back too short and who does not know why

FAQ
Does it generate the music?
No. It produces the plan and the prompts. You run them in Suno.
Where does it run?
On your machine, inside your own agent client, using your own subscription. Nothing is metered by the seller and nothing is uploaded.
Do I need an API key or a Suno connection?
No. The skill is plain Markdown instructions. It never touches your Suno account.
Which clients does it work in?
Anything supporting the Agent Skills folder format — Claude Code, Codex, OpenClaw, Hermes. It is a SKILL.md plus reference files; there is no code to run.
Which generator is it written for?
Suno's Styles field, and it names the UI settings that go with it. The architecture, variation rules and delivery specs transfer to any generator; the exact prompt grammar is Suno-shaped.
Can it do one track instead of a pack?
Yes — ask for a single slot and you get that row plus its length-risk check.
Can I ask for a pack in a genre that is not in the twelve palettes?
Yes. Describe the sound and it builds the palette from the same template.
Can I edit the files?
Yes. Change the palettes, adjust the slot tables, alter the output format — it is yours to modify for your own use. You may not redistribute or resell the files themselves; see LICENSE.txt.
Will it copy a specific game's soundtrack?
No. It will not write prompts naming an artist, composer, band, or franchise. Describe the sound you want — instrumentation, tempo, era, mood — and you get the descriptive equivalent, which is also the version that will not create a rights problem for you later.
Limits — please read before buying
- Plans, not audio. If you want finished music files, this is the wrong product.
- No guarantee of a specific musical result. Generators are stochastic. This raises your hit rate and cuts wasted credits; it cannot promise a given take will be good.
- No commercial-rights clearance. Whether your generated music can be sold depends on your generator subscription tier at the moment of generation and on each storefront's own AI policy. The plan tells you what to verify — it is not legal advice and does not clear your material for sale.
- Storefront policies change. Anything stated about a specific marketplace is as of the reference date and must be re-checked on the day you list.
- No sales or revenue claims. A production plan is not a commercial outcome.
- Licence. Personal or single-organisation use, including commercial projects. Redistribution or resale of the skill files is not permitted. Full terms in
LICENSE.txt.
