What it is
claude-devtools is a debugging tool for Claude Code. It reads the Claude Code logs and session transcripts saved on your machine and reconstructs transcripts, tool calls, token usage, and subagent trees in a visual UI.
How it works
The project reads local Claude Code logs from ~/.claude and presents per-turn token attribution across multiple categories, along with execution trees, tool traces, and token metrics. It offers a project memory viewer and a compaction visualization to show context usage.
