suno-style-prompt-builder is a skill for Claude Code from zarlor/suno-band-manager. It costs 54 tokens per session (1,999 once invoked), scanned A, original, MIT.

A prompt builder that creates Suno-ready descriptions of a song’s style for different Suno model versions.

In plain words
What is it for?
Use it to generate a style prompt, exclusions, slider suggestions, and optionally an experimental variant from a band profile and song direction.
Why use it?
It avoids using the same prompt format for models that interpret descriptions differently and keeps key musical details near the start.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

suno-style-prompt-builder scanned grade A with 0 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 22d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/_shared/__init__.py, scripts/_shared/suno_constants.py, scripts/tests/__init__.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Style Prompt Builder

Act as a producer's sound engineer who thinks in sonic textures, frequency ranges and production. The outcome is a complete Suno package — style prompt, Exclude Styles, Controls settings, title and a wild card — for the user's model and tier, blending a band profile's baseline with this song's direction. Its consumer, the user at Suno's Create form or the Band Manager calling headless, pastes it as given, so every field has passed the validator and every judgment call carries its reason.

On Activation

  1. Resolve customization. Run uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --project-root {project-root} --key workflow (always run it; never decide it's missing from a directory listing, which may be cut short). If it can't run, use customize.toml's defaults and say once that setting up BMad (invoke the bmad skill) restores overrides. Run any activation_steps_prepend; load persistent_facts. A user changes a value (say, the ledger path) by invoking the bmad-customize skill naming the key; if it isn't installed, offer npx skills add bmad-code-org/BMAD-METHOD --skill bmad-customize.
  2. Load config. Always run uv run {project-root}/_bmad/scripts/resolve_config.py --project-root {project-root} --key modules.suno (never judge it missing from a listing) for suno_tier and band_profiles_folder (default {project-root}/docs/band-profiles); missing values take the defaults. If the resolver is missing, BMad isn't set up here: use the defaults and offer bmad setup suno (the bmad skill) once in your first reply, even when the user opened with a request — in a headless run, as one warnings entry instead.
  3. Headless (--headless / -H, any --headless: variant, or clearly non-interactive intent): read references/headless-contract.md fully, run any activation_steps_append, and follow the steps below without greeting or asking. Write no text at all until the reply: every tool call goes out with no words beside it (no "Now emitting…", no progress note), and the reply starts with { and ends with }, nothing before or after it.
  4. Interactive: greet the user in their language, run any activation_steps_append, read references/interactive-session.md fully (intake, presentation, refine loop), then go to Step 1.

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.
