Rederive
Rederive is a coding agent skill that teaches codebases by guiding users to design them from first principles.
Rederive is a skill for coding agents that teaches codebases by making developers design systems from first principles instead of memorizing explanations. It asks targeted questions and guides users to the correct answers while withholding direct explanations. A background agent maps the repository by reading code, import links, and commit history to build a sequence of problems and constraints. The system narrows down problems when users get stuck and logs performance notes locally. It runs locally with git, bash, and python3, sends no telemetry, and is available under an MIT license.
