Culpa enables zero-cost deterministic agent replays

Culpa addresses the "reproducibility crisis" in agent development by turning non-deterministic LLM sessions into predictable, debuggable snapshots.

• –Captures file system changes, terminal commands, and LLM calls in a high-fidelity session log
• –Proxy mode allows integration with black-box tools like Claude Code and Cursor without source code access
• –"Forking" capability enables counterfactual testing, letting developers tweak past decisions to see divergent outcomes
• –Zero-cost replays make regression testing financially viable for complex, multi-step agent workflows
• –Lightweight, local-first architecture avoids the privacy and latency overhead of cloud-based observability platforms
