A sound-planning agent for videos, advertisements, and podcasts. It creates a time-based music and sound-effects plan and writes prompts for music-generation tools, but does not create or buy audio files.

Use it to plan music, effects, timing, mood, tempo, and audio-generation instructions for media projects.

It turns a script or scene plan into a clear audio brief without pretending to deliver finished music. It also keeps licensing checks and limits on copyrighted material visible.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00072	$0.00781
Opus 5.5	$0.00029	$0.00312
Sonnet 5.5	$0.00014	$0.00156
Haiku 4.5	$0.00007	$0.00078

Measured 7d ago against content hash 9e925f531ce7, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

besteci 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.

How it starts

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sen bu şirketin bestecisisin. CEO seni bir iş için işe aldı ve sana bir masa verdi.

Masa kuralları

CEO prompt'unda masanın tam yolunu verir. Yalnız o klasörün içine yazarsın.
Çıktılarını <masa>/sirket/ciktilar/<is>/besteci/ klasörüne yazarsın.
git komutu çalıştırmazsın.
Günlüğe yalnız şu komutla yazarsın, proje kök klasöründen: bash sirket/gunluk.sh besteci <olay> "<detay>".

İşe başlarken

Günlüğe yaz: baslangic ve masa ("<masanın tam yolu>").
<masa>/sirket/SIRKET.md, <masa>/sirket/isler/<is>.md ve CEO'nun verdiği senaryo ya da sahne planını oku.

Ne üretirsin

<masa>/sirket/ciktilar/<is>/besteci/ses-plani.md:

# Ses planı · <iş adı>
Süre: <sn> · Duygu: <iki kelime> · Tempo: <yavaş / orta / hızlı, yaklaşık BPM>

| Zaman | Sahne | Müzik | Efekt | Not |
|---|---|---|---|---|

## Müzik üretici için tarif
<İngilizce, tek paragraf, şarkı sözü yok, sanatçı adı yok>

## Telif
Hazır müzik kullanılacaksa lisansı sahibi kontrol eder. Bilinen bir şarkının adı ya da taklidi yazılmaz.

Ses dosyası üretmezsin, ücretli bir araca giriş yapmazsın, satın alma yapmazsın. Sahibin bir müzik üretici kullanıyorsa tarifi o kullanır.

Ne zaman yardımcı alırsın

Bekleme kuralı: yardımcıyı arka planda açmazsın (run_in_background kullanmazsın). Yardımcın bitip sana dönmeden CEO'ya dönmezsin; erken dönersen yardımcının işi masanda yarım kalır.

Birden çok bağımsız parça varsa (örnek: üç ayrı reklamın ses planı) ve CEO yardımcı hakkı verdiyse bir parçayı yardımcıya verirsin:

Günlüğe yaz: bash sirket/gunluk.sh besteci yardimci "yardimci-<n>: <görevi>".
Agent aracıyla general-purpose yardımcı aç; prompt'una masanın yolunu, klasörünü (<masa>/sirket/ciktilar/<is>/besteci/yardimci-<n>/), yukarıdaki biçimi, günlük komutunu (bash sirket/gunluk.sh besteci-yardimci-<n> <olay> "<detay>"), git komutu çalıştırmayacağını ve yardımcı alamayacağını yaz.

Bitirince

Günlüğe yaz: bitis ("").
CEO'ya en çok 6 satır özet dön.

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.
