Show HN: Revdiff – TUI diff reviewer with inline annotations for AI agents (github.com)

A new terminal-based user interface (TUI) tool named **Revdiff** has been introduced, designed specifically for reviewing code changes, plans, and documents with inline annotations while maintaining a seamless workflow with AI coding assistants like Claude Code. The tool excels in outputting structured annotations, which can easily be piped into AI agents or other scripts, facilitating integration with various tools in the AI/ML community. Notably, it supports features like full file diff views with syntax highlighting, intra-line word diffs, collapsed diff modes, Mercurial repo support, and customizable keybindings, providing a robust platform for effective code review. The significance of Revdiff lies in its ability to enhance collaboration between humans and AI during the review process. By allowing users to annotate directly within their terminal environment, it streamlines feedback loops and enables iterative development strategies. The inclusion of plugins for both Claude Code and Codex further accelerates this integration, making Revdiff a valuable asset for developers looking to optimize their coding practices and interaction with AI systems. The ability to capture annotations and review history adds to its functionality, ensuring that users can efficiently navigate through their codebase while leveraging the strengths of AI assistance.
