SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps users compare two documentation corpora to identify gaps, overlaps, and discrepancies, ensuring that documentation remains aligned with current codebases.

Core Features & Use Cases

  • Gap Analysis: Identify missing ideas or concepts in one corpus compared to another.
  • Overlap Analysis: Determine where the two corpora agree or diverge.
  • Use Case: Compare an old design corpus with a current vision layer to find discrepancies and ensure documentation is up-to-date.

Quick Start

Run the compare-doc-corpora skill with the reference corpus path 'old-design-corpus' and the current corpus path 'current-vision-layer'.

FAQPage Schema
How do I compare two documentation corpora to find gaps and overlaps?

To compare documentation corpora, you analyze both text sets to identify missing ideas and determine where they agree or diverge. This ensures your documentation aligns with the current codebase.

What is documentation gap analysis and when do I need it?

Documentation gap analysis identifies missing ideas or concepts in one text corpus compared to another. You need it when verifying that old design documentation remains aligned with a current vision layer or updated codebase.

How do I check if my old design corpus aligns with my current vision layer?

You check alignment by running a corpus comparison with the reference path set to the old design corpus and the current path set to the vision layer. This outputs a structured analysis report detailing discrepancies.

Can I use this approach to find discrepancies between any two sets of documentation?

Yes, you can compare any two accessible documentation corpora to find discrepancies. The process requires reading and analyzing text from both sets to determine where they diverge or overlap.

What do I need to analyze documentation overlap and ensure codebase alignment?

You need access to both documentation corpora and the ability to read and analyze text. The system processes these inputs to produce a structured analysis report identifying overlaps and gaps.

What are the limitations of comparing documentation corpora for gap analysis?

The primary limitation is the absolute requirement for access to both documentation corpora to perform text analysis. Without readable text from both the reference and current sets, generating a structured gap analysis report is not possible.
