Sandboxed Coding

• Key points are in the visual diagram above.

Understanding Sandboxed Coding helps you build reliable, scalable agent applications instead of fragile demos.

Think of Sandboxed Coding as a specialized capability in your Coding Agents engineering toolkit.

Scenario

A production team in Coding Agents uses Sandboxed Coding to handle a real user request — reducing manual work and improving response quality with proper validation and logging.

Solution

In Coding Agents, apply Sandboxed Coding to this scenario: A production team in Coding Agents uses Sandboxed Coding to handle a real user request — reducing manual work and improving response quality with proper validation and logging. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

Do this before moving to the next module — reading alone is not enough.

Open the Code Walkthrough below and run it locally. Change one parameter related to Sandboxed Coding (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

Highlighted lines show where Sandboxed Coding happens in the code.

• Skipping evaluation for Sandboxed Coding before production
• No logging or tracing around sandboxed coding steps
• Ignoring cost and latency implications
