Individual skill
wasm-emscripten
Use when compiling C or C++ to WebAssembly with emcc, exporting functions to JavaScript, sizing WASM memory, using Asyncify, or debugging .wasm. Not for server-side runtimes: use wasm-wasmtime.

# WebAssembly with Emscripten
## Contract
| Field | Bound contract |
|---|---|
| Trigger | C or C++ to WebAssembly through Emscripten: emcc flag selection, JavaScript exports, memory sizing, Asyncify, wasm-opt, browser debugging, or a standalone `.wasm` output. |
| Authority | Reversible local. Writes are limited to build outputs under the project tree; rollback is deleting the build directory. No remote mutation. |
| Side effect | Generated `.js`, `.wasm`, and `.html` build artifacts and a build recipe. |
| Done | The code compiles for a named Emscripten version and target environment, exports are callable from JavaScript, and the memory and optimization settings match the workload. |
## Inputs
1. Source (required): the C or C++ to compile.
