Constraint-First Architecture Brief

Use When

• A user needs to constrain a V1 plan or architecture before implementation.
• A project needs explicit build, simplify, defer, and forbid decisions.

Do Not Use When

• The user only wants a visually polished architecture diagram.
• The request is a pure execution task with no scope or system-boundary decision.

Inputs

• PRD
• architecture document
• meeting notes
• roadmap

Outputs

• executive thesis
• atomic capability inventory
• value complexity quadrant
• decision register
• phased roadmap

Trigger Phrases

• constraint-first architecture
• build simplify defer forbid
• V1 scope
