SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams generate or incrementally update a PROJECT_MAP.md for user-specified directory ranges within a codebase, avoiding full-repo scans and improving documentation navigation and maintainability.

Core Features & Use Cases

  • Precise scope scanning: require explicit folder ranges and disable default full-repo scans.
  • Incremental updates: if PROJECT_MAP.md exists, only apply changes to the relevant sections while preserving history.
  • Flexible output: write a merged map at the project root or generate separate maps for each directory, depending on user preference.
  • Transparent handling of uncertainties: label unknowns as "assumed" or "not confirmed" and provide a clear update log.

Quick Start

Provide the folders you want to scan and choose an output strategy (merge to project root or separate per directory). Then run the skill to generate or update PROJECT_MAP.md.

Frequently Asked Questions about project-map-builder

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a project map for specific directories instead of scanning the whole repository?▼

To generate a project map for specific directories, you specify the exact folder ranges you want to scan. The tool then creates or updates a PROJECT_MAP.md file for only those directories, avoiding a full-repo scan to improve documentation navigation.

Can I update an existing PROJECT_MAP.md without losing previous history?▼

Yes, you can update an existing PROJECT_MAP.md without losing history. The tool performs incremental updates, applying changes only to relevant sections while preserving the existing documentation and update log.

What is the best way to document module relationships and entry points in a codebase?▼

The best way to document module relationships and entry points is to generate a structured PROJECT_MAP.md. This file systematically records entry points, configurations, and module relationships within your specified directory scope.

How are uncertainties handled when generating codebase documentation for unknown configurations?▼

When generating codebase documentation, uncertainties are handled transparently by flagging them as assumed or not confirmed. This approach ensures unclear configurations are explicitly labeled in the PROJECT_MAP.md.

Can I generate separate project maps for each directory instead of one merged file?▼

Yes, you can generate separate project maps for each directory. The tool offers flexible output strategies, allowing you to write a merged map at the project root or create individual maps per directory based on your preference.
