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-designer 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 10d 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-designer — produce all the sound the clip maker requested

A silent Short feels dead. Visual motion is only half of "not slop"; sound builds the rest of the scene in the viewer's head — a gust of wind, a low cello, a distant bell, and the still becomes a place. You are the audio half of art-direction: the clip maker (script + visuals) hands you scenes; you decide and produce the music arrangement + per-scene sfx for them, as cheaply as possible.

The flow: request → produce

  1. Read the run. runs/<id>/01_script.json — each Scene has narration, visual_prompt, mood/tone, and possibly existing sfx cues; the top-level Script.music is the bed/arrangement mood. Eyeball the visuals if useful (runs/<id>/02_visuals/*.png).
  2. Inspect the available library before choosing.
    find assets/audio/music assets/audio/sfx -maxdepth 1 -type f 2>/dev/null | sort
    sed -n '1,220p' assets/audio/CREDITS.md 2>/dev/null
    
    If fal is available and budget allows, prefer paid/generated fal audio for quality. If using community/library audio, only use local files with explicit reusable rights or Freesound CC0/public-domain beds (scripts/fetch_music.py). Fall back to synth when nothing fits.
  3. Design per scene + the music. Decide:
    • Script.music — ONE coherent mood/arrangement phrase for the whole video (not per-scene). Include movement when useful: "fade in slowly", "swell at the reveal", "drop to near silence after the quote", "soft outro". The renderer currently creates one bed, so use this phrase to shape the bed and use SFX cues for precise accents.
    • per-scene Scene.sfx — a list of {prompt, at, dur, gain_db} cues, only where the scene literally depicts a sound source or where a small musical accent supports a real story beat. Accent cues should usually be 0.2-2.0s; 5.0s is the hard maximum unless the scene visibly needs ambience (wind/rain/crowd). Long bells, drones, rumbles, and ambiences are not accents.
  4. Write it into 01_script.json (edit the music field + each scene's sfx list).
  5. Produce by running the audio stage, then re-muxing voice:
    studio audio <id> --music-provider local --sfx-provider local   # best if a suitable local/Freesound bed exists
    # fallback: studio audio <id> --music-provider synth --sfx-provider local
    studio voice <id>                                                # ducks music under narration
    studio save  <id>
