Claude Code usage monitor
What Claude Code is doing between your prompt and its answer, drawn live from the logs it already writes: every model call, every tool, each subagent on its own context window and its own model, and what the session produced. Local and read-only — your session content never leaves the machine.
A fast codebase indexer and knowledge wiki for AI agents.
