Analysis updated 2026-06-24
Paste the thinking protocol into claude.ai custom instructions to force step-by-step reasoning.
Install the Chrome extension to fold Claude's long reasoning into collapsible sections.
Read the protocol files as a study example for designing your own reasoning prompts.
Fork the extension as a starting point for a browser tool that reformats LLM output.

Project is retired, the protocol still works as a custom instruction but the extension may lag behind current claude.ai DOM changes.
Thinking Claude is a now-retired project that aimed to make Claude (an AI assistant) reason more carefully and show its thought process before giving answers. The project has been officially retired because Claude's built-in reasoning capabilities have since improved enough to make this add-on unnecessary. While it was active, the project had two main pieces: a "thinking protocol" (a set of detailed instructions you could paste into Claude's custom instructions settings to guide it through a more systematic, step-by-step reasoning process before replying) and a browser extension for Chrome that made Claude's internal thinking process easier to read, collapsing and expanding sections, letting you copy parts, and organizing the output cleanly. To use it, you'd paste one of the included instruction files into Claude's custom style settings on claude.ai, and the browser extension would automatically format any thinking Claude displayed into readable, collapsible sections. This made long reasoning chains much easier to follow. The project was not designed to improve Claude's performance on math benchmarks or hard logic puzzles, the creator was more interested in exploring how deeply Claude could reason through everyday tasks, and in making that inner monologue visible and fun to read. The repository is written in TypeScript and was available for Chrome (with a Firefox version in development at the time of retirement).
Retired project that gave Claude a step-by-step thinking protocol via custom instructions, plus a Chrome extension that formatted the chain-of-thought into collapsible sections.
Mainly TypeScript. The stack also includes TypeScript, Chrome Extension, JavaScript.
Setup difficulty is rated easy, with roughly 5min to a first successful run.
Mainly vibe coder.
