What you'll learn
Design a sandboxed environment for testing agentic systems
choose the right isolation level (containers, VMs, or mocked tools) based on the task and risk.
Build an Eval Harness That Scores Agent Behavior
Capture tool calls, state changes, and reasoning traces; grade on task success, safety, and efficiency.
Run Repeatable Evals on Non-Deterministic Agents
Reset state between runs so results are comparable and failures are reproducible.
Why this topic matters
Agents don't just generate text, they take actions: running code, calling APIs, editing files. Testing them in production risks real damage, and non-deterministic behavior makes results hard to trust or reproduce.
As agentic systems move into production, engineers need a safe, repeatable way to evaluate what agents actually do, not just what they output. Sandboxed evals are how you build that confidence before shipping.
