What is a codemap in the context of this skill?

A codemap is a token-lean Markdown file that summarizes the high-level structure, exports, and dependencies of a specific part of your codebase, such as the backend or data models.

Where can I see the history of architectural changes?

Detailed diff reports are saved to .reports/codemap-diff.txt, allowing you to review exactly how your project's structure has evolved over time.

Will this skill modify my source code?

No, it only analyzes your source code to update documentation files within the 'codemaps' directory and generate reports.

How does the 30% change threshold work?

To prevent accidental or massive overwrites, the skill calculates the difference between the new analysis and the old documentation; if the change is greater than 30%, it pauses for user approval.

Content Management

Automates the generation and maintenance of high-level architecture documentation by analyzing codebase structure and dependencies.

This skill streamlines technical documentation by scanning source files to create token-lean 'codemaps' that visualize the relationships between frontend, backend, and data layers. It helps developers maintain an accurate mental model of their project by calculating structural diffs and requesting approval for significant architectural shifts. By automating the tracking of imports, exports, and dependencies, it ensures that your project documentation stays in sync with the actual code, providing a reliable source of truth for onboarding and system design.
