The repository contains links to alpha-stage projects like Chidori, which may not be suitable for immediate deployment. ## When NOT to use lean-ctx - When there is a dependence on cloud-based solutions for context intelligence, since LeanCTX operates as a local binary. - If your setup does not need context layering or token optimization. In such cases, using LeanCTX would incur overhead without providing significant benefits. ## Common questions ### What is the difference between awesome-ai-sdks and lean-ctx? awesome-ai-sdks: A database of SDKs for AI agents creation and management. lean-ctx: Control what your AI can see by serving context with a local Rust binary..
