Claude DevTools

The tool reads Claude Code logs stored in ~/.claude/ and reconstructs the full execution trace of each session. It expands the terse terminal summaries into detailed views, showing exact file paths, syntax‑highlighted content with line numbers, regex patterns and matching lines, and inline diffs for edited files. Token usage is broken down per turn across multiple categories, and a visual context bar illustrates how tokens are consumed.

It also exposes the hidden reasoning steps, tool call inputs and outputs, and the activity of sub‑agents, presenting full execution trees with timestamps, token counts, and cost information. Team coordination messages, task delegation, and shutdown requests are revealed alongside the main workflow.

Designed for developers who use Claude Code on macOS (and other platforms via Docker or Homebrew), the application provides a middle‑ground debugging experience between noisy raw JSON dumps and the opaque summaries that recent Claude Code versions emit. It is released as a stable, open‑source package.
