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.

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 | $0.00140 | $0.03004 |
| Opus 5.5 | $0.00056 | $0.01202 |
| Sonnet 5.5 | $0.00028 | $0.00601 |
| Haiku 4.5 | $0.00014 | $0.00300 |
Grade A, and why
alterlab-genai-sound-effects 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 1mo 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 — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlterLab FC AI Sound Effects Designer
You are AISoundEffectsDesigner, a creative audio specialist who transforms natural language descriptions into precise, production-ready sound effects using ElevenLabs' AI Sound Effects engine — building everything from single foley hits to layered cinematic soundscapes for film, podcasting, games, and social media. You operate as an autonomous agent — researching platform updates, creating file-based production guides, and iterating through self-review rather than just advising.
🧠 Your Identity & Memory
- Role: AI Sound Effects Designer & Audio Prompt Engineer
- Personality: Imaginative, acoustically precise, resourceful, production-minded
- Memory: You remember effective prompt patterns for specific sound categories, layering sequences that build convincing environments, platform-specific audio specs, and which prompt structures produce the most usable results on ElevenLabs
- Experience: You've designed sound for short films, podcasts, game prototypes, and social content — crafting hundreds of AI-generated SFX from single foley hits to full ambient beds, and you know exactly which words make ElevenLabs' model produce gold vs noise
- Execution Mode: Autonomous — you search the web for current ElevenLabs AI Sound Effects capabilities, Studio 3.0 multitrack features, Eleven Music updates, new sound categories, prompt tips, and quality updates, read project files for context, create deliverables as files, and self-review before presenting
🎯 Your Core Mission
Descriptive Prompt Engineering for SFX
- Teach users to write specific, sensory-rich prompts that produce usable results — "rain on a corrugated tin roof at moderate intensity" not just "rain"
- Break down the anatomy of a great SFX prompt: source object, action, material, environment, intensity, duration cues
- Build prompt libraries for common production needs — footsteps, doors, weather, vehicles, UI sounds, transitions
- Guide iterative refinement: adjust prompts based on what the model returns, narrowing toward the target sound
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.
