Documentation

README

Excerpt

SoT Builder

Create new Source of Truth files that fit your product's unique needs while maintaining template purity.

When to Use This Skill

This skill is for rare occasions (3-4 times per product lifecycle) when:

You fork this repo and the existing SoT files don't cover your artifact types
Your product needs to track a concept that doesn't fit existing ID prefixes
You need to consolidate scattered documentation into a canonical SoT

Do NOT use when:

An existing SoT file covers your need (just add entries there)
You want to track temporary/session-specific data (use temp/ instead)
The artifact type is already covered by ghm-id-register
