Kaizen CLI, published by Kaizen 3C and currently at version 1.0.3 (with two versions listed in the catalog), is a command-line tool in the software modernization and code migration category. Its purpose is architecture-driven modernization: it decomposes legacy codebases into editable Architectural Decision Records (ADRs) and then recomposes those records to modern technology stacks, producing an audit trail by default so that every transformation decision remains traceable. This approach suits engineering teams responsible for large, aging codebases who need a documented, reviewable path away from outdated languages and frameworks rather than an opaque one-shot conversion. The tool supports two key workflows. The first, invoked as "kaizen memsafe-roadmap," assists with migrating C and C++ code to Rust and generates memory-safety roadmaps in the CISA format, making it relevant for organizations aligning with memory-safety guidance and reducing vulnerability exposure in systems code. The second, "kaizen migrate-plan," targets framework modernization, covering upgrades from technologies such as AngularJS, .NET Framework, and Java 8 to their modern equivalents. Typical use cases include planning and executing language migrations, modernizing legacy web and enterprise frameworks, capturing architectural decisions in an editable ADR format for ongoing governance, and maintaining an audit trail of modernization activity for compliance or review purposes. Because the tool relies on large language model APIs for its analysis and generation capabilities, operation requires an API key to be configured in advance: either the ANTHROPIC_API_KEY or OPENAI_API_KEY environment variable must be set before running the workflows. Kaizen CLI therefore positions itself at the intersection of architecture documentation, legacy migration tooling, and AI-assisted code transformation, offering development teams a structured, decision-record-based method for moving from legacy stacks to modern platforms while preserving the reasoning behind each change.
