Reversa: A Multi-Agent Framework for Reverse Engineering Legacy Software into AI-Readable Operational Specifications

Reversa is a multi-agent pipeline framework that converts legacy software systems into traceable operational specifications suitable for use by AI coding agents. The framework employs specialized agents for surface mapping, module analysis, implicit rule extraction, architecture synthesis, and specification review, with mechanisms for traceability, confidence marking, and gap preservation. An exploratory case study on migrating an ATM system from COBOL to Go produced 517 confidence-indexed claims, 53 Gherkin parity scenarios, and a partial reconstruction plan, though final validation was not completed. The system is distributed as a Node.js CLI and is positioned relative to literature on reverse engineering, LLM-based documentation, and software agents.
