# How to pull apart a game's web build with rea

Repo: [morluto/rea](https://github.com/morluto/rea) | Difficulty: Advanced | Time: 1 hour | Basis: Seen in the wild

Use your agent to inspect a game's WASM web build and surface what it contains.

**Who it is for:** Hobbyist or modder who wants to know how a cross-platform game's web build is put together

**The problem:** The web version ships as compiled WebAssembly, which you cannot read directly.

**The outcome:** A decoded view of the WASM imports, exports and sections, plus the agent's notes on what they suggest.

## Steps

1. Run npx rea-agents setup and restart your agent.
2. Download or locate the .wasm file from the game you are allowed to inspect.
3. Ask your agent to inspect the WASM artifact with REA and decode it.
4. Ask it to explain the notable imports and exports.

## Prompt to paste into your agent

```text
Use REA to inspect the WASM artifact at <path to .wasm>, decode its sections and imports/exports, and explain what stands out. Verify against the decoded output and flag any guesses.
```

## Caveat

WASM decoding needs the caller-supplied WABT 1.0.42 toolchain. Only inspect builds you have the right to analyze.
