rx-plugin

This is a plugin for Claude Code (the AI coding assistant) that sets up a two-part workflow for writing code changes. Claude acts as the planning layer: it understands what you want, writes a specification document, and verifies whether the result is correct. A separate tool called Reasonix actually makes the changes to your codebase. Reasonix is powered by the DeepSeek AI model, which costs considerably less to run than Claude. The author claims this combination is 30 to 40 times cheaper than having Claude do all the work directly.

The workflow starts when you describe a task in Claude Code using the /rx:go command. Claude reads the codebase, writes a specification file, and hands it off to Reasonix. Reasonix calls the DeepSeek API to implement the changes. Claude then runs a four-step verification process and, if something is wrong, loops back up to three times before stopping.

The plugin includes a gatekeeper hook that prevents Claude from directly editing your project files when a change exceeds three lines. This enforces the separation between the planning role and the execution role: Claude is not supposed to touch the code itself, only to direct the tool that does. The hook is active as long as the plugin is enabled.

Two built-in skills extend the workflow further. One runs a test-driven development loop where Claude writes the tests and Reasonix writes the implementation to pass them. The other runs a parallel code audit from multiple angles simultaneously, covering security, performance, testing, user experience, and general quality.

Using this plugin requires Claude Code installed, Node.js, Python 3, bash, and a DeepSeek API key that you obtain separately from DeepSeek's platform. The repository is written primarily in Shell and documented in Chinese. It is licensed under MIT.
