Decision Documentation Sync

Activation Contract

Load this skill when a change introduces or changes a structural decision: architecture, UI/UX standards, scripts or quality gates, or a cross-cutting convention.

Hard Rules

1. Check which documents exist before editing; update only documents that exist, and create one only when a rule below requires it.
2. Keep each fact in one document and link to it from others instead of duplicating it.
3. Record the decision itself, not the change history.
4. Never leave a document contradicting the code after the change.
