Show HN: Ctxdiff – Git diff for your LLM agent's context window

Description and use

**Project Summary:** Ctxdiff is an open-source project that integrates Git diff capabilities with a Large Language Model (LLM) agent's context window, enabling users to prototype AI features, build Retrieval-Augmented Generation (RAG) workflows, and evaluate model tooling without starting from scratch.

**Value Proposition:** The value of Ctxdiff lies in its ability to streamline the development process for AI capabilities, allowing users to build and test AI features quickly and efficiently. This is particularly useful for prototyping and internal workflows where speed and flexibility are crucial.

**Practical Adoption Path:** To adopt Ctxdiff, users need to manually inspect the project before integrating it into their workflows. This involves verifying the license, maintenance, documentation, issues, and release cadence to ensure that the project meets their needs. Once integrated, users can leverage Ctxdiff to prototype AI features, build RAG workflows, and evaluate model tooling, making it an ideal solution for medium-production readiness environments.

**Production Readiness:** Ctxdiff is considered to have medium production readiness, indicating that it is useful for prototypes or internal workflows but requires dependency and maintenance checks before being deployed in production environments. This is due to the limited quality signals and the need for manual inspection before adoption.
