What it does
Vitexec is an agent skill from pmndrs/viverse. Use this skill when an AI agent needs to inspect, verify, debug, or profile a live Vite app by running temporary snippets inside the browser page and reading browser logs or captured artifacts. Use for client state after interactions, imported app modules, DOM state, human-like input, canvas/WebGL/Three.js state, screenshots, videos, CPU/network/performance/heap analysis, WebXR/Three.js XR with IWER, and runtime-only behavior without editing app files.
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/inputs.md` and `references/performance.md`).
It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js, Vite and npm. The repository describes itself as: ⟁ Toolkit for building Three.js and React Three Fiber Apps for VIVERSE and beyond.
When your agent uses it
- An AI agent needs to inspect
- Profile a live Vite app by running temporary snippets inside the browser page and reading browser logs
- Captured artifacts
- Client state after interactions
Example prompts
- “/vitexec”
Requirements
- Node.js
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Identify the page path if it is not /.
- Write the smallest snippet that performs the user-like action or reads the browser-only state.
- Run vitexec '', adding --path, --gpu, --screenshot, --record, --cpu-profile, --network-trace, --performance-trace, --heap-snapshot…
- Treat stdout as browser logs. It starts with logs:.
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:
npmpnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and pnpm, which can reach the network depending on how they are called.
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
Vitexec loads about 2.5k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 116 tokens; SKILL.md has 1,265 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,265 words (~2,496 tokens).
“Use vitexec when the truth lives in the running browser: client state, imported app modules, DOM, canvas/WebGL, screenshots, recordings, or browser-only errors.”
