description: Agent Diff creates isolated, ephemeral replicas of third-party APIs (Slack, Linear, GitHub). Agents interact
  with these sandboxes to produce deterministic state-change diffs without side effects, rate limits, or real API calls. Ideal
  for testing AI agents that interact with external APIs.
