claude-devtools Inspector

Skill by ara.so — Devtools Skills collection.

claude-devtools is the missing DevTools for Claude Code. It reads session logs from ~/.claude/ and reconstructs everything Claude Code hides: tool calls, token usage, subagent trees, thinking steps, context window breakdown, and memory layers. Works with all existing sessions — no wrapper, no API keys, no configuration.

What claude-devtools Does

• Session inspection: View full transcripts of any Claude Code session with syntax-highlighted messages
• Tool call visibility: See exact inputs/outputs for Read, Edit, Bash, Search, and all other tools
• Token attribution: Per-turn breakdown across 7 categories (CLAUDE.md, skills, @-mentions, tool I/O, thinking, team overhead, user text)
• Context compaction: Visualize when context hits limits and what gets compressed/dropped
• Subagent trees: Isolated execution traces for nested agents with cost/duration metrics
• Memory viewer: Browse project memory layers stored in ~/.claude/projects/<project>/memory/
• Thinking steps: Full extended thinking content that's invisible in the terminal
• Copy/paste: Export sessions to Markdown/JSON, one-click copy on code blocks
