Purpose
Thinking-Claude aims to make Claude think comprehensively before giving an answer. The author states that this project does not pursue benchmark scores or a major leap in mathematical ability, but rather explores how far Claude's "deep thinking" can go. When used in daily tasks, users will find Claude's internal monologue (thinking process) very interesting. The project is designed for both the free and Pro versions of the Claude web app, in conjunction with the Claude 3.5 Sonnet model.
Main Capabilities
The project contains two main components:
-
Thinking Protocol: A complete set of instructions that guides Claude to think deeply and systematically before answering. The model instructions are organized by version in the
model_instructions/folder, and each version improves Claude's thinking process. -
Browser Extension: Makes Claude's thinking process easier to read and manage in the browser interface. Features include:
- Automatically organizing Claude's thinking into neat collapsible blocks
- Collapsing and expanding different parts of the thinking
- One-click copying of any part
- Automatically handling new messages
- A clean and modern design
The extension's code structure is as follows:
extensions/: Browser extension implementationchrome/: Current version, using a modern architecture and featureschrome_v0/: Old version (deprecated)firefox/: Firefox version (in development)
Usage

Use cases
- When you want more comprehensive, thoughtful answers
- When you want to understand how Claude reaches conclusions, improving transparency
- When you need better management of long conversations
- When you benefit from quality control with built-in verification steps
Limitations and current status
This repository has been retired. The author explains that Claude itself is already a reasoning model with powerful built-in thinking capabilities, so this project is no longer necessary. The project uses the MIT license, and bug reports, new feature suggestions, or pull requests are welcome. The Chrome Web Store version of the extension may be outdated, and manual installation is the recommended method; the Firefox version is still under development.
