The core argument is that AI agents fail at modernization not due to code generation limitations, but because they cannot reliably understand complex legacy codebases — citing tests showing Claude Code achieved only 35% code coverage and 70% accuracy on a COBOL codebase with 42% variance between runs. Swimm 2.0 addresses this with deterministic static analysis that extracts business rules, decision logic, and data flows directly from source code, then uses AI only as a translation layer into business language. New features include business-domain navigation, Collections for governing modernization plans, source-traced business rules, an MCP server for AI agents to consume pre-validated context, and broad legacy language support including COBOL, CICS, and JCL. The platform claims up to 90% reduction in manual reverse engineering time, 75% time savings, and 61% cost reduction when agents use Swimm's context versus raw code. ## Full article daily.dev links to this article rather than hosting it.
