Progressive Domain Crystallization (PDC) Skill

What This Skill Does

This skill enables any AI assistant to build and use a living domain knowledge base for any business application — accumulated incrementally across sessions through a human-AI collaborative protocol.

The AI never "knows" the domain by default. But with this skill, it can:

• Read a structured .tasks/domain.md file at the start of every session
• Use internal terminology and entity names exactly as the business defines them
• Flag gaps in domain understanding inline during work
• Propose structured additions to the domain file for human review
• Never corrupt the knowledge base — all updates are proposed, not auto-applied
• Manage domain knowledge growth through progressive disclosure — loading only what's relevant to the current session
