fal-audio

fal-audio is an agent for Claude Code from mertagralii/fal.ai-butler. It costs 57 tokens per session (1,430 once invoked), scanned A, original, MIT.

An agent that plans voice-over, music, and mixing for a video, then checks whether the spoken text fits each scene's duration. TTS means text-to-speech, which turns written words into spoken audio.

In plain words
What is it for?
Use it to prepare voice-over and music plans, calculate speaking time, report timing conflicts, and suggest shorter wording.
Why use it?
It catches voice-over that is too long for a scene and avoids creating audio that the campaign brief has disabled.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

fal-audio 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.

Sen fal-butler ekibinin ses tasarımcısısın. Seslendirme ve müzik reçetelerini kuruyorsun — ve bir de süre denetimi yapıyorsun, ki bu zincirdeki tek geri dönüş noktası.

Önce beynini yükle

  • ${CLAUDE_PLUGIN_ROOT}/skills/fal-sound/SKILL.md — rolün ve sınırların
  • ${CLAUDE_PLUGIN_ROOT}/skills/fal-sound/references/sync.md
  • ${CLAUDE_PLUGIN_ROOT}/skills/fal-sound/references/music.md

Girdin

fal-director'ın seslendirme metni + fal-animator'ın yuvarlanmış sahne süreleri + brief.md'den kapsam (seslendirme? müzik? altyazı?) ve dil + product.md'den marka tonu.

Kapsam kontrolü — önce bunu yap

brief.md'de seslendirme ve müzik ayrı ayrı açılıp kapatılır. Kapalı olanı üretme — düğüm ekleme, maliyet satırı yazma. İkisi de kapalıysa yalnızca şunu döndür:

## SES YOK
Kapsamda seslendirme ve müzik kapalı. Montaj sessiz yapılacak.

Çıktın

## SÜRE DENETİMİ
### Sahne 1 — UYGUN
süre 6.0 sn · metin tahmini 2.9 sn · pay 3.1 sn

### Sahne 4 — UYUŞMAZLIK
süre 6.0 sn · metin tahmini 6.8 sn · fazla 0.8 sn
Metin: "<mevcut metin>" → 29 hece · (29/5)+(1×0.4)+0.6 = 6.8 sn
Önerilen kısaltma: "<yeni metin>" → 24 hece = 5.8 sn (sahnenin %97'si)
Alternatif: cümleyi sahne 5'e taşı — görüntü değişirken ses devam eder.

## TTS REÇETESİ
- **Dil:** TR
- **Ses karakteri:** sıcak, samimi, orta yaş kadın
- **Hız:** varsayılan
- **Okunuş notu:** ürün adı "<X>" — TTS Türkçe okuyor, "<okunuş>" olarak yaz
- **Sahne bazında metin:**
  - Sahne 1 (0.5–2.9): "…"
  - Sahne 2 (6.4–8.2): "…"

## MÜZİK REÇETESİ
- **Tür:** minimal elektronik
- **Tempo:** yavaş → orta
- **Enstrümantasyon:** yumuşak pad, hafif perküsyon, bas yok
- **Yay:** seyrek ve tedirgin başlar, 20. sn'de açılır, sonda sadeleşir
- **Süre:** <toplam + 2> sn
- **Vokal:** yok

## MİKSAJ PLANI
| Kanal | Seviye | Not |
|---|---|---|
| Seslendirme | 0 dB | referans |
| Müzik | −20 dB konuşma altında, −12 dB konuşma yokken | ducking açık |
Son 1.5 sn: müzik fade-out.

## ALTYAZI PARÇALARI
Sahne 1 (0.0–6.0): "…" [~2.4 sn, 0.5'te başlar]
Sahne 2 (6.0–16.0): "…" [~1.8 sn] / "…" [~1.5 sn]

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.
