threejs-debug-profiler

threejs-debug-profiler is a skill for Claude Code, Codex from mintdotgg/mint-threejs-skills. It costs 35 tokens per session (386 once invoked), scanned A, original, MIT.

A troubleshooting guide for Three.js, a JavaScript library used to display 3D graphics in web browsers. It uses reproduction, error checks, and measurements to find causes of rendering, loading, input, and performance problems.

In plain words
What is it for?
Use it to investigate broken 3D scenes, missing assets, animation, audio, physics, touch or keyboard input, resizing, mobile behavior, and slow performance.
Why use it?
It helps avoid changing code based on guesses. It connects each problem to the part of the application that owns it and requires retesting after the fix.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

threejs-debug-profiler 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 5d 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.

What it actually says

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

  1. Reproduce in the correct build mode.
  2. Read the first console, page, and relevant network errors.
  3. Check canvas display/drawing-buffer size, renderer/context, and loop ownership.
  4. Check camera, clipping, lights, fog, materials, visibility, transforms, and scene contents.
  5. Check asset paths, loaders, CORS, base path, async ordering, and Mint artifact integration.
  6. Check delta units, update order, fixed timestep, bodies/colliders, listeners, pointer/touch behavior, resize, and audio unlock/decode.
  7. Fix the cause in the owning module.
  8. Retest the broken path plus screenshot, canvas pixels, and errors.

Performance Workflow

  1. Record target device, viewport, DPR, build mode, and worst-case scenario.
  2. Measure frame time/FPS, draw calls, triangles, resources, memory, bundle, and expensive shadows/shaders/post-processing.
  3. Identify CPU, GPU, memory, or network ownership.
  4. Change one bottleneck at a time using reuse, instancing, culling, LOD, pooling, disposal, DPR limits, or cheaper rendering.
  5. 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.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
