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

music-song 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 11d 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.

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.

What it actually says

/music-song — Suno URL → catalog draft

Capture a Suno-generated song into the Music IS catalog as a draft row, queue asset render, register in label/persona indexes.

Usage

/music-song https://suno.com/song/abc123 frank-riemer evening-piano
/music-song https://suno.com/song/xyz789 pulse-01 lo-fi-evening

Arguments

  • suno-url (required) — Suno song URL or extension share URL
  • persona (required) — persona codename; rejection if not provided or invalid
  • intent (optional) — short tag like "evening-journal", "gym-peak", "score-grade"

Behavior

Invokes music-is/song-intake skill (Mechanical tier, Haiku 4.5):

  1. Validates persona (must be active in verticals/music-is/labels/<label>/personas/<persona>/CANON.md)
  2. Extracts Suno metadata (title, prompt, BPM, duration, structure tags)
  3. Generates song-id: <persona>_<YYYYMMDD>_<short-slug>
  4. Writes catalog/master.csv draft row + catalog/draft/<song-id>.md
  5. Registers in persona's releases-index.md
  6. Dispatches music-producer (Sonnet 4.6) to queue asset render bundle (cover + motion + Canvas; +Higgsfield for cinematic-grade labels)
  7. Returns: catalog row written, draft md path, asset queue status, next-step suggestion

Refusals

  • No persona attribution → orphan track refused
  • Persona not registered in active LABELS.md
  • Engine not declared in STACK.md L2
  • Vocal track using non-Frank cloned voice without consent doc on file
  • Duplicate intake (idempotent; use update path for revisions)

Composes with

  • /music-suno-prompt — generate the prompt that produces the URL
  • /music-release — gate the song after asset bundle complete

Changes

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.
