Code Execution & Sandboxing

• Key points are in the visual diagram above.

Unexpected code execution is an OWASP 2026 agentic top risk.

A lab behind glass.

Scenario

Scenario (Claude Agent SDK): A user triggers a workflow that depends on Code Execution & Sandboxing. Code execution must be sandboxed: no network unless allowlisted, no secrets, CPU and time caps, workspace root. Your implementation handles the request, logs the step for observability, validates the output, and returns a grounded response — e.g. cutting manual work from 20 minutes to under 30 seconds.

Solution

In Claude Agent SDK, apply Code Execution & Sandboxing to this scenario: Scenario (Claude Agent SDK): A user triggers a workflow that depends on Code Execution & Sandboxing. 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 Code Execution & Sandboxing (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 Code Execution & Sandboxing happens in the code.

• Skipping evaluation for Code Execution & Sandboxing before production
• No logging or tracing around claude code execution steps
• Ignoring cost and latency implications
