Code Execution with dev

Execute code directly using the Bash tool. No wrapper, no persistent files, no cleanup needed beyond what the code itself creates.

Run code inline

# JavaScript / TypeScript
bun -e "const fs = require('fs'); console.log(fs.readdirSync('.'))"
bun -e "import { readFileSync } from 'fs'; console.log(readFileSync('package.json', 'utf-8'))"

# Run a file
bun run script.ts
node script.js

# Python
python -c "import json; print(json.dumps({'ok': True}))"
