What it does

Threejs Audio Generator is an agent skill from valkor-ai/loom. Generate, convert, clean, and integrate audio for Three.js browser games with ElevenLabs: sound effects, looping ambience, UI sounds, impact/weapon/vehicle audio, creature and boss stingers, announcer and dialogue TTS, voice conversion from a scratch performance, voice cleanup, audio manifests, and Web Audio integration.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/audio-workflows.md` and `scripts/threejs_audio_asset.py`).

It sits in Game Development, covering 3D graphics and WebGL, Text to speech and voice and Music and audio generation. It works with Three.js and ElevenLabs. The repository describes itself as: Loop engineering for agentic software delivery. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL
  • Tasks that involve Text to speech and voice
  • Tasks that involve Music and audio generation

Example prompts

  • “/threejs-audio-generator”

Requirements

  • Python 3
  • A credential in ELEVENLABS_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit a30a7e6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ELEVENLABS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Threejs Audio Generator loads about 1.3k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 501 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Generate, convert, clean, and integrate audio for Three.js browser games with ElevenLabs: sound effects, looping ambience, UI sounds, impact/weapon/vehicle audio, creature and boss stingers, announcer and dialogue TTS, voice conversion from a scratch performance, voice cleanup, audio manifests, and Web Audio integration.

Three.js Audio Generator

Game-ready audio for Three.js projects: generation, voice work, cleanup, and runtime integration. Provider: ElevenLabs.

Resolve <this-skill-dir> from the actual loaded skill file. Resolve sibling skills beside it first, then use the runner's discovered paths. Do not mix installed versions or assume a particular home directory.

Reference

references/audio-workflows.md — the audio matrix, prompt patterns, generation and voice strategy, Web Audio manager shape, and runtime failure modes. Read it before planning a game's audio, generating a batch, wiring runtime playback, or converting voices.

When to use

SFX (jumps, hits, weapons, explosions, pickups, collisions, UI clicks) · ambience (wind, rain, city bed, engine hum, room tone, arena beds) · voice (announcer barks, boss lines, tutorial prompts, menu narration) · voice conversion from a scratch performance when timing and acting matter · cleanup and isolation before conversion or final use · Web Audio integration with loading, looping, manifests, volume groups, pause/resume, and gesture unlock.

Audio is not cosmetic for a premium game. Build an audio matrix from the events the game actually has; do not add dialogue, weapons, or ambience layers just to fill categories. Respect explicit silent, procedural-audio, accessibility, and external-service constraints. A narrow sound fix does not need a new soundtrack.

API key

The script reads --api-key or ELEVENLABS_API_KEY. Keys never go in skill files, game code, or reports.

bash
python3 <this-skill-dir>/scripts/threejs_audio_asset.py probe   # ELEVENLABS_API_KEY=SET|MISSING

Keys defined only in a shell profile can be absent from the process env; threejs-game-director/scripts/probe_asset_credentials.sh sources the profile and probes all three providers.

Add --validate to call GET /user and confirm the key actually works (prints VALID_USER=...) when a key is present but generation fails. A valid key can still be blocked by credit or plan limits, which surface as an HTTP 4xx from a real generation attempt — report that as a plan blocker rather than a missing key.

Commands

Run from the game project directory:

bash
python3 <this-skill-dir>/scripts/threejs_audio_asset.py sfx \
  --prompt "tight futuristic boost pickup, bright transient, short sparkling tail, arcade racing game" \
  --duration 1.2 --prompt-influence 0.65 --out assets/audio/sfx/boost-pickup.mp3

python3 <this-skill-dir>/scripts/threejs_audio_asset.py sfx \
  --prompt "seamless cyber resort ambience, distant surf, soft neon transformer hum, gentle crowd bed" \
  --duration 12 --loop --prompt-influence 0.45 --out assets/audio/ambience/cyber-resort-loop.mp3

python3 <this-skill-dir>/scripts/threejs_audio_asset.py tts \
  --text "Perfect shot." --voice-id JBFqnCBsd6RMkjVDRZzb --out assets/audio/voice/perfect-shot.mp3

python3 <this-skill-dir>/scripts/threejs_audio_asset.py isolate \
  --input assets/audio/source/noisy-boss-line.wav --out assets/audio/voice/boss-line-clean.mp3

python3 <this-skill-dir>/scripts/threejs_audio_asset.py voice-change \
  --input assets/audio/source/scratch-boss-line.wav --voice-id JBFqnCBsd6RMkjVDRZzb \
  --remove-background-noise --out assets/audio/voice/boss-line-final.mp3
Show full SKILL.md (201 more words)Show less

Defaults

  • SFX: mp3_44100_128, 0.5–2.5s, prompt influence 0.55–0.8.
  • UI: 0.15–0.8s, high prompt influence, transients kept clear.
  • Ambience: 8–30s with --loop, prompt influence 0.3–0.55.
  • Voice: TTS for clean generated lines; voice-change when timing and acting from a scratch performance matter. Isolate noisy speech first.
  • Runtime: generate into the game project and load through Web Audio. Follow the project's asset/version-control policy; do not commit or publish unless asked. No API keys in browser code.

Recovery and Coordination

For coordinated games use the director's references/asset-recovery.md. Preserve outputs and the audio trigger mapping before retrying work. Distinguish missing credentials, permissions, exhausted credits, invalid input, and transient service failures. Reconcile an uncertain paid request before resubmitting; these one-shot commands do not implement Tripo task resume. Keep independent gameplay work moving and provide a local/synthesized fallback with honest limitations when genuinely blocked.

Listen to a representative effect or line before generating a batch. Test it through its real game event, then give the lead paths and local playback findings for one consolidated QA pass.

Report

Generated and processed file paths, the prompts, text, source files, voice IDs, durations, loop flags and formats behind them, the runtime trigger mapping and audio groups, and any remaining gaps or plan limits.
