Tsl

What it does

When your agent uses it

• Storage buffers
• Shader-node typing
• GLSL-to-TSL work
• Verify every API against the repositorys installed Three.js version

Example prompts

• “/tsl”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Read the nearest package.json, renderer setup, material or pass being changed, TypeScript configuration, and relevant tests.
2. 2Record the installed three and @types/three versions. Inspect their exports, declarations, and shipped examples before inventing an…
3. 3Preserve the existing renderer and public boundaries unless the request explicitly includes a migration. TSL is the right tool for a…
4. 4Identify the execution surface before coding

What it can do on your machine

Read from SKILL.md and the folder at commit 51a1f34. 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 (its code samples are typescript).

  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

Tsl loads about 1.5k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 641 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~85

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

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

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.

Implement, migrate, review, debug, or verify Three.js Shading Language (TSL) materials, node graphs, WebGPU compute work, and post-processing. Use for `three/tsl`, `three/webgpu`, NodeMaterial, WebGPURenderer, storage buffers, shader-node typing, or GLSL-to-TSL work; verify every API against the repository's installed Three.js version.
