What it does
An open-source desktop app that reads Claude Code session files on your machine and draws the subagent and workflow structure as a live graph. Each node shows latency, token cost and nesting depth. Token spend is split by source, such as the base session, skills, subagents and MCP, and can be traced back to the message that caused it.
Use cases
- 01Find which subagent branch is stuck
- 02See which skill or MCP server uses the most tokens
- 03Trace a cost bucket back to a single message
