What it does
Optimize Threejs Games is an agent skill from nirholas/three.ws. Profile, diagnose, and improve Three.js or WebGL game performance without regressing gameplay. Use for frame-time drops, CPU/GPU pressure, draw calls, texture and geometry budgets, animation loops, adaptive quality, mobile performance, and browser performance verification.
Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.
When your agent uses it
- Frame-time drops
- CPU/GPU pressure
- Texture and geometry budgets
- Animation loops
Example prompts
- “/optimize-threejs-games”
What it can do on your machine
Read from SKILL.md and the folder at commit 238ef60. 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
No scripts in the folder and no shell commands in SKILL.md.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Optimize Threejs Games loads about 421 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 170 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.

Optimize Three.js Games
Measure before changing behavior, then validate the same gameplay path after every optimization.
Establish a repeatable scene
Choose a deterministic representative encounter and record device, viewport, quality level, player position, enemies, active effects, frame-time sample, draw calls, triangles, texture count, and warnings. Compare like with like.
Diagnose the limiting side
- Suspect CPU when simulation, allocations, React work, pathfinding, or per-frame scans grow with actors.
- Suspect GPU when resolution, overdraw, shadows, transparent particles, post-processing, draw calls, geometry, or texture bandwidth dominate.
- Inspect before optimizing; do not lower quality blindly.
Apply low-risk fixes first
Reuse geometry/materials, pool transient effects, cull inactive/offscreen work, throttle noncritical UI updates, cap particle counts, avoid per-frame allocation, and update only changed transforms. Keep render quality settings explicit and reversible. Degrade decorative effects before combat readability or controls.
Guard the result
Re-run the original encounter and verify frame time, visual correctness, collision/contact behavior, memory stability, mobile controls, reduced motion, and console health. Close temporary servers, benchmarks, and browser tabs once they are no longer needed.
