Agent Diff

aid: agent-diff
name: Agent Diff
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.
