What it does
Records a Claude Code run through a local proxy and replays it offline. A replay reproduces the run exactly with the network off, or forks it from any checkpoint onto a different model. Shell exit codes, per-turn file changes and MCP calls sit on the same timeline as the model traffic. The project is marked as early.
Use cases
- 01Reproduce an agent run that broke something
- 02Review shell results and file changes turn by turn
- 03Fork a run onto another model and compare outcomes
