Summary

Codemode public docs claim Typescript is supported. However, attempts to execute TS seem to fail due to TS-specific syntax errors.

Workaround

Prompting to only use Javascript is successful.

To Reproduce

1. Create an AI Agent using the Agents SDK and give it the codemode tool
2. Give a specific prompt asking to execute Typescript
3. Observe codemode syntax errors

Example

execute a basic Typescript function and show me any errors

✗ code: code
✗ code: code

I attempted to execute a TypeScript function, but it appears the code execution environment doesn't support TypeScript syntax (it likely only runs JavaScript). Here's what happened and what I can show you instead:

The error you'll see with TypeScript code execution:

SyntaxError: Unexpected token ':'

Here's a JavaScript equivalent that would work:

function add(a, b) {
  return a + b;
}

function greet(name) {
  return `Hello, ${name}!`;
}

// This line would cause an error if we had TypeScript type checking
const greeting = greet(123); // We'd get a type mismatch warning in TypeScript

// Works fine
const sum = add(5, 3);
console.log(sum); // Output: 8
