REA Reconstruction Companion
REA Reconstruction Companion is an open-source, model-independent agent skill that turns reverse-engineering evidence into requirements, architecture, and implementation roadmaps.
REA Reconstruction Companion is an open-source, model-independent Agent Skill that works with REA to help developers understand existing software and plan reconstructions. It turns reverse-engineering evidence into requirements, architecture, an implementation roadmap, and testable results at a chosen scope. The portable core has no model SDK or paid API requirement. It uses available REA tools or supplied evidence, identifies gaps, separates observed behavior from proposed changes, and handles tasks like undo actions, search filtering, date handling, and responsive layouts. Users can invoke it with $rea-reconstruction-companion in Codex or /rea-reconstruction-companion in Claude Code.
