Design Tree Core

Overview

This skill is the shared governance core for the design-tree skill family.

It is not a general design skill. It is not a user-facing entrypoint for normal design work. It exists to define the minimum shared contract that all design-tree skills must honor.

Its job is to protect only the rules that stay stable across the family:

• required design_state fields (including the mandatory design_target_type)
• design_target_type vocabulary and the prohibition on silent inference
• derivation criteria
• parent/child handoff contracts
• anti-bloat governance
