Playbook Tools

Local utilities for Claude Code introspection and optimization.

cc-tools

CLI suite that reads your local Claude Code session logs (~/.claude/projects/**/*.jsonl) and surfaces:

• cost-ledger — per-session cost, subagent (sidechain) vs main-loop split, tool-call frequency
• cache-radar — prompt-cache hit rate, worst-offender sessions, $ saved
• md-lint — CLAUDE.md / AGENTS.md linter: line-cap, duplicates, hedging language, contradictions

No deps. Stdlib only. No network. See cc-tools/README.md for usage.

cd tools/cc-tools
python3 -m cctools cost-ledger --days 7
python3 -m cctools cache-radar --days 30
python3 -m cctools md-lint ~/.claude/CLAUDE.md
