TypeGPU

TypeGPU schemas, typed buffers/textures, shader functions, pipelines, WebGPU capability checks, and CPU/GPU resource ownership.

Operating Contract

Use this skill as a compact router plus domain checklist. Load references only when the current task matches their condition. Do not cite local scrape paths, machine cache paths, or hidden source locations. Verify API details against the target repo's installed package versions before editing.

Source Order

1. Inspect the target repo's installed packages, framework/runtime versions,

local design tokens, accessibility policy, and existing motion patterns.

1. Use the bundled references below for skill-specific gotchas and copied source

excerpts.

1. Use official current docs/package source as API truth when local code or

bundled notes are version-sensitive.

Decision Boundaries

• Do not trigger for raw WebGPU without TypeGPU imports.
• Use web-three-r3f for Three/R3F scenes.
• Use native-three-r3f or native-skia for React Native GPU surfaces.

Workflow

1. Check installed typegpu, unplugin-typegpu, @webgpu/types, tsover, and browser/runtime support.
2. Define schemas before resources and shader signatures.
3. Keep root/device/resource ownership explicit.
4. Validate unsupported-browser fallback, reduced-motion/static quality, and GPU cleanup.

Gotchas

• A d.* schema is the CPU layout, GPU layout, and TypeScript type source of truth.
• TypeScript shader functions require unplugin-typegpu; WGSL-only usage may not.
• Do not allocate buffers, textures, bind groups, or pipelines per frame unless measured and cached.

Audit CLI

node scripts/audit.mjs doctor --root . --format json
node scripts/audit.mjs scan --root . --format markdown
node scripts/audit.mjs scan --root . --format json --output typegpu-audit.json

Treat script findings as leads. Verify every finding against current code before changing behavior or reporting it as valid.

Closeout

Before finalizing, run the repo's focused validation command, this skill's audit CLI when relevant, and any browser/device/manual proof required by the changed surface. Report commands run, findings fixed, findings skipped with reasons, and residual risk.
