Use cases

• Record tool-call sequences for audit and debugging
• Replay workflows in tests without spending tokens
• Diff runs to detect agent behavior drift

Pros

• Zero-token deterministic replay
• Concrete receipts of what the agent did
• Simple run comparison for drift-catching

Cons

• Covers tool-call workflows only, not full reasoning
• Requires recording a workflow before replaying
• Early-stage project with limited community traction
