What it does

Pmndrs Viverse is an agent skill from pmndrs/viverse. Build, modify, debug, or publish VIVERSE-ready web games and 3D apps with Three.js, React Three Fiber, @pmndrs/viverse, @react-three/viverse, VIVERSE SDK integrations, character controllers, physics, avatars, actions, animations, AR, or VR.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 19 other files, including reference files (for example `agents/openai.yaml`, `references/components-and-hooks.md` and `references/gameplay-quality.md`).

It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js and React. The repository describes itself as: ⟁ Toolkit for building Three.js and React Three Fiber Apps for VIVERSE and beyond.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/pmndrs-viverse”

Workflow steps

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

  1. Inspect the app structure and package manager before editing.
  2. Identify whether the task needs React Three Fiber or vanilla Three.js.
  3. Pick the smallest relevant reference before inventing APIs.
  4. Keep VIVERSE apps character-first: prefer the standard character/avatar path unless the requested controls or animation semantics require…
  5. Build game rules, sensors, UI, level geometry, and validation around normal user inputs and the visible player.
  6. Validate live gameplay with the app's browser/runtime behavior, not only static state.
  7. Use the bundled skill references and installed package types as the example source. For tutorial assets, use only exact asset URLs or…

What it can do on your machine

Read from SKILL.md and the folder at commit b88c0e7. 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

    Shell commands in SKILL.md call:

    • rg

    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

Pmndrs Viverse loads about 1.7k tokens when it runs, and up to ~37k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 814 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~37k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 814 words (~1,695 tokens).

“Use this skill for VIVERSE-ready Three.js and React Three Fiber apps. Use @react-three/viverse for React apps and @pmndrs/viverse for vanilla Three.js.”
