Thinker is a Node.js CLI that reduces token consumption for coding agents by compressing tool output via a local Anthropic Messages API proxy, caching session knowledge into reusable notes, and analyzing instruction files for cuts. It integrates with a broad range of agents (Claude Code, Codex, Cursor, Gemini CLI, Devin, etc.) and exposes a local web UI plus session-time suggestions, making token economics observable and actionable.

Target audience: AI-assisted developers and DevOps engineers using coding agents
