Multi-language Workers development with Rust, Python, and WebAssembly. Use when building Workers in languages other than JavaScript/TypeScript, or when integrating WASM modules for performance-critical code.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Multi-Language Workers Development

Build Cloudflare Workers using Rust, Python, or WebAssembly for performance-critical operations.

## Language Comparison

| Feature | JavaScript/TS | Rust | Python |
|---------|---------------|------|--------|
| **Startup** | Fast | Fastest (WASM) | Moderate |
| **CPU Perf** | Good | Excellent | Good |
| **Memory** | Higher | Lower | Higher |
| **Bundle Size** | Smaller | Medium | Larger |
| **Type Safety** | Optional (TS) | Strict | Optional |
| **Best For** | General apps | CPU-intensive | Data/ML |

## Quick Decision

```
Need maximum performance? → Rust/WASM
Heavy computation (crypto, image processing)? → Rust/WASM
Data processing, ML inference? → Python
General web apps? → JavaScript/TypeScript
```

## Top 10 Multi-Lang Errors

| Error | Language | Cause | Solution |
|-------|----------|-------|----------|
| `WebAssembly.instantiate() failed` | Rust | Invalid WASM | Check wasm-pack build output |
| `Module parse failed: Unexpected token` | Rust | ESM/CJS mismatch | Use `--target bundler` |
| `Cannot find module` | Python | Missing dep | Add to pyproject.toml |
| `Out of memory` | All | Large WASM | Enable streaming instantiation |

How to install

The exact contents, by fingerprint
mdr add secondsky/claude-skills/cloudflare-workers-multi-lang@sha256:d4540ce033cd84af

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
