Q: How do I install threejs-audio-generator?

Run npx skills add https://github.com/majidmanzarpour/threejs-game-skills --skill threejs-audio-generator in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/threejs-audio-generator/ (personal) or .claude/skills/threejs-audio-generator/ (project).

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/majidmanzarpour/threejs-game-skills --skill threejs-audio-generator

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads threejs-audio-generator automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Three.js Audio Generator

Game-ready audio for Three.js projects: SFX, music, 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, music, 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) · music (menu and gameplay loops, boss themes, intensity layers, win/lose stingers) · 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, music, 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.

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:

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 music \
  --prompt "driving synthwave race loop, 128 BPM, punchy analog bass, bright arpeggios, steady energy with no intro or fade-out, designed to loop" \
  --duration 60 --instrumental --out assets/audio/music/race-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

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.
Music: music --prompt (--duration 3–600s, --instrumental) or --plan FILE with a composition_plan JSON for sectioned tracks (--seed works only with plans). The API has no loop flag; lengths, looping, and layering are in the reference's Music Strategy.
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, composition plans, text, source files, voice IDs, durations, loop flags and loop points and formats behind them, the runtime trigger mapping and audio groups, and any remaining gaps or plan limits.
