Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.01192 |
| Opus 5 | $0.00039 | $0.00596 |
| Sonnet 5 | $0.00016 | $0.00238 |
| Haiku 4.5 | $0.00008 | $0.00119 |
Grade A, and why
audio-track 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio Track
REQUIRED BACKGROUND: marketing-studio skill. Work in ${CLAUDE_SKILL_DIR}/../...
Read ${CLAUDE_SKILL_DIR}/../../docs/playbook/audio.md first (endpoints, ducking, manifest contract).
Every film gets this pass; it is not opt-in (CLAUDE.md: a film is not done without
audio, and audio means narration). node scripts/check-audio.mjs <brand> --project <product> is the exit
gate for all three recipes that touch video.
Three modes; pick by what the target is:
- Bespoke film (
studio/src/films/<brand>/, e.g. PostflopFilm) — post-render scoring withscripts/build-<brand>-film-audio.mjs+scripts/score-film.mjs. Recipe A0. - Video soundtrack — a directed LaunchVideo composition scored with music and voiceover inside the product workspace. Recipe A.
- Standalone audio — a music track and/or narration mp3s delivered as files (a sting, a jingle, a narration for something outside this studio). Recipe B.
Both need ELEVENLABS_API_KEY in the repo .env (missing key = feeder exits 2;
videos stay silent). Generation costs real money: one pass, trim copy rather than
regenerate blindly. Free tier returns 402; Starter or above required.
Recipe A0: bespoke film
- Shared-repo guard + toolchain per marketing-studio.
- Copy source of truth:
scripts/build-<brand>-film-audio.mjs(copy postflop's). Narration lines carry the film SECOND they start on, computed from the film's timeline.ts so a re-timed shot moves its line with it; SFX cues carry the frame the shot lands something on (Stamp/Rule/click constants + the shot'sfrom), max two per beat. Budget ~2.6 words/second minus a 150ms breath per line. - Run it (VO lines and the exact-length bed hit the API once; re-runs reuse files,
--force <id,...|music>regenerates). Read the printed start/end table: every line inside its shot. node scripts/score-film.mjs <brand> <product-film> --project <product>— refuses overlapping lines (trim copy, re-run the builder) and zero-VO manifests; masters by measured gain and verifies the DELIVERED file (I within 0.5 of TARGET_I, TP <= -1).- Listen-proof:
node scripts/verify-cue.mjs <scored.mp4> <voStart> <voDur>on one narration window and one bed-only window (voice ~6 dB above the bed), thennode scripts/check-audio.mjs <brand> --project <product>(exit 0), then SEND the scored file.
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.

audio-track is a skill published in the GitHub repository ucsandman/marketing-studio (234 stars, last pushed 3d ago), licensed MIT. It adds 79 tokens to every session and 1,192 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
