Terminal tells you nothing.
This shows you everything.

A desktop app that reconstructs exactly what Claude Code did — every file path, tool call, and token — from the session logs already on your machine.

Session complete.

Which 3 files? What pattern? What changed?

Your only option is --verbose, which dumps raw JSON, system prompts, and thousands of lines of noise. There is no middle ground.

Not a wrapper. Doesn't touch Claude Code.

Reads ~/.claude/ — the session logs already on your machine. Works with every session you've ever run, from any tool.

What you're missing

Claude Code's terminal summaries strip out the details. claude-devtools puts them back.

Key Features

Context Reconstruction

Per-turn token attribution across 7 categories — CLAUDE.md (global, project, directory), skill activations, @-mentioned files, tool I/O, thinking, team overhead, user text. Visualizes how your context fills, compresses during compaction, and refills — so you can see exactly what was in the window at any point.

Tool Call Inspector

Syntax-highlighted Read calls, inline Edit diffs, Bash output, and full subagent execution trees. Every collapsed "Read 3 files" expanded.

Team & Subagent Trees

Isolated execution trees per agent with their own tool traces, token metrics, duration, and cost. Nested agents render as recursive trees.

Notification Triggers

System notifications with built-in alerts for .env file access, tool execution errors, and high token usage. Add regex triggers for sensitive paths (for example payment/billing files), match specific tool fields, set input/output/total token thresholds, and filter by trigger color.

SSH Remote Sessions

Inspect sessions on any remote machine over SSH. Reads ~/.ssh/config, supports agent forwarding and key auth. Switch between local and remote instantly.
