Where is the documentation stored?

It generates standard markdown files within your repository, such as tech-debt.md and migration-plan.md, ensuring documentation lives alongside your code.

How does it help with migrations?

It collects your migration goals and target architecture preferences to generate a structured roadmap and tech-debt registry for modernization.

MAGS Legacy is a Claude Code skill designed to help AI understand, document, and manage existing, undocumented codebases (brownfield projects).

How does it detect my tech stack?

The skill uses specialized discovery tools to scan your repository for specific language, framework, API, and database patterns to provide a comprehensive summary of your stack.

Can I use this for new projects?

While this skill is optimized for legacy projects, you can use the related /mags-init command for new (greenfield) projects.

Initializes comprehensive documentation and context tracking for existing legacy codebases to facilitate migrations and maintenance.

MAGS Legacy is a specialized capability for Claude Code designed to onboard AI to brownfield or legacy repositories that lack formal documentation. It streamlines the process of understanding existing code by automatically detecting technology stacks and discovering module structures. By guiding developers through the creation of technical debt registries, architecture diagrams, and migration plans, this skill ensures that project context and critical decisions are preserved across coding sessions, making it significantly easier for Claude to provide accurate assistance on complex, pre-existing systems.
