💻 AgentSnap: A tool for deterministic snapshot testing of AI agents.

AgentSnap has been released—a tool that records an agent's "golden run" and compares subsequent runs against it based on structure, arguments, and semantics. It supports mocking popular SDKs (Anthropic, OpenAI, Google Gemini) without requiring code changes.

🌍 Solves the problem of regression in AI agents, making development more predictable.

👤 Allows for guaranteeing system stability after updates, saving on API calls.
