What it does
Threejs Debug Profiler is an agent skill from mintdotgg/mint-threejs-skills. Diagnose Three.js rendering, loading, animation, resize, audio, physics, input, mobile, and performance problems using reproduction and measured evidence.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/debug-profile-checklists.md`).
It sits in Game Development, covering 3D graphics and WebGL and Performance optimization. It works with Three.js. The repository describes itself as: Agent guidance for building polished Three.js apps and games with Mint MCP. The licence is MIT.
When your agent uses it
- Tasks that involve 3D graphics and WebGL
- Tasks that involve Performance optimization
Example prompts
- “/threejs-debug-profiler”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Reproduce in the correct build mode.
- Read the first console, page, and relevant network errors.
- Check canvas display/drawing-buffer size, renderer/context, and loop ownership.
- Check camera, clipping, lights, fog, materials, visibility, transforms, and
- Check asset paths, loaders, CORS, base path, async ordering, and Mint artifact
- Check delta units, update order, fixed timestep, bodies/colliders, listeners,
- Fix the cause in the owning module.
- Retest the broken path plus screenshot, canvas pixels, and errors.
What it can do on your machine
Read from SKILL.md and the folder at commit de7af44. 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
Threejs Debug Profiler loads about 435 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 199 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.

Three.js Debug Profiler
Find the owning cause or measured bottleneck before changing code.
Read references/debug-profile-checklists.md for the applicable render,
runtime, loading, mobile, audio, physics, or performance path.
Debug Workflow
- Reproduce in the correct build mode.
- Read the first console, page, and relevant network errors.
- Check canvas display/drawing-buffer size, renderer/context, and loop ownership.
- Check camera, clipping, lights, fog, materials, visibility, transforms, and scene contents.
- Check asset paths, loaders, CORS, base path, async ordering, and Mint artifact integration.
- Check delta units, update order, fixed timestep, bodies/colliders, listeners, pointer/touch behavior, resize, and audio unlock/decode.
- Fix the cause in the owning module.
- Retest the broken path plus screenshot, canvas pixels, and errors.
Performance Workflow
- Record target device, viewport, DPR, build mode, and worst-case scenario.
- Measure frame time/FPS, draw calls, triangles, resources, memory, bundle, and expensive shadows/shaders/post-processing.
- Identify CPU, GPU, memory, or network ownership.
- Change one bottleneck at a time using reuse, instancing, culling, LOD, pooling, disposal, DPR limits, or cheaper rendering.
- Re-measure the same scenario and verify playability and visuals.
Final Response
Lead with root cause or bottleneck. Report files changed, baseline/post metrics, commands, screenshots/artifacts, retested paths, and residual risks.
