What it does
Reads the session logs Claude Code already writes to disk and shows what a session is doing while it happens. You see each model call and tool, the context window filling, every subagent with its own model, and the commits and files produced. It is read-only and runs locally in a browser view.
Use cases
- 01Watch the context window fill during a long task
- 02Check which model each subagent used
- 03Review the files and commits a session produced
