sound-sync-brief-fit

sound-sync-brief-fit is a command for Claude Code from frankxai/Starlight-Intelligence-System. It costs 51 tokens per session (1,652 once invoked), scanned A, original, MIT.

A check performed before proposing a music placement in a film, show, advertisement, or other project. It compares the brief with the catalog, available masters, rights situation, and the artist's stated boundaries.

In plain words
What is it for?
Use it to decide whether a brief fits, document the reasons for passing or refusing, and send the work to the correct next step.
Why use it?
It prevents unsuitable pitches and flags rights or artistic conflicts before time is spent pursuing a placement.

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

sound-sync-brief-fit 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 7d 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.

/sound-sync-brief-fit

Load verticals/sound-intelligence/SKILL.md, verticals/sound-intelligence/SOUL.md, verticals/sound-intelligence/MEMORY.md, agents/starlight-sound-sync.md, skills/sound-intelligence/sync-licensing.md, the catalog state files at sound-intelligence/catalog/<release-state-files> if present in the practitioner's runtime vault (this path is instance-state, not substrate-shipped), and active vision boundaries from MEMORY.md. Produce a Brief-Fit Verdict — pass to placement thesis OR refuse with documented rationale. Hand off to exactly one next command.

Disclaimer (non-waivable)

Sync placement decisions touch rights law, contributor splits, sample clearances, AI involvement disclosure, and brand-association liability. This is system architecture, not legal advice. Every specific placement requires sign-off from the practitioner's qualified music counsel. Vision-boundary refusal is non-waivable; the boundary either holds or gets revised at MEMORY.md level deliberately, never "this once" under deal pressure.

Input

$ARGUMENTS

Process

  1. Disclaim. Non-waivable opener.
  2. Read brief. Brief content, source (library / direct-supervisor / brand / agency), budget range if disclosed, timeline, content context (film / TV / commercial / trailer / branded content / political / video game / etc.), exclusivity request.
  3. Axis 1 — Catalog match. Does the practitioner have tracks that fit the brief? Search catalog by mood / tempo / instrumentation / lyric-or-instrumental / emotional arc against brief requirements. Three or more matching candidates → pass. Two matches → conditional pass (named gap). Zero or one match → refuse-on-catalog OR route to Composition for purpose-built work (rare; only when budget justifies).
  4. Axis 2 — Master availability. For each candidate track: does the master state allow placement? Rights structure permits sync (no exclusivity-elsewhere conflict)? Sync-availability flag true in metadata? Alternate-master available if brief specifies (sync-grade-dynamic-range master vs. streaming master)?
  5. Axis 3 — Rights structure. Per candidate: splits documented; sample clearances complete; AI involvement disclosed (per /sip-attest-audio doctrine); contributor consents on file. Any incomplete clearance → flag and refuse on this axis until resolved.
  6. Axis 4 — Vision-boundary respect. Pull active vision boundaries from MEMORY.md. Common: refuses-political-campaign-sync, refuses-violence-soundtrack, refuses-extractive-fossil-fuel-brand, refuses-AI-vocal-impersonation-license-out, refuses-children's-content-without-curated-fit. Per-practitioner the list varies. Compare brief to each active boundary. Any contradiction → non-waivable refuse. The deal pressure does not override; if the boundary is to be revised, that revision happens at MEMORY.md, deliberately, not "this once."
  7. Verdict synthesis.
    • All four axes pass → PROCEED to /sound-sync-placement-thesis.
    • Catalog or master axis fails → REFUSE-ON-AXIS, document, no further sync work for this brief.
    • Rights-structure axis fails → REFUSE-PENDING-CLEARANCE, document gaps, route to clearance work before re-running.
    • Vision-boundary axis fails → REFUSE-ON-BOUNDARY, document, communicate the refusal honestly to brief source if relationship warrants.
  8. Document refusal. Refusals are first-class artifacts. The refusal-on-boundary letter (when relationship warrants) is in practitioner's voice via Genius — direct, warm, non-apologetic, non-compromising.
  9. Save. Write to sound-intelligence/sync/brief-fit-<brief-slug>-<YYYY-MM-DD>.md.
  10. Hand off. Name exactly one next move:
    • PROCEED → /sound-sync-placement-thesis.
    • REFUSE-ON-CLEARANCE → clearance work (sample clearance, contributor-split documentation, AI disclosure).
    • REFUSE-ON-BOUNDARY → refusal letter (if relationship warrants); MEMORY.md boundary update if practitioner wants to deliberately revise (rare).

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.
