# Technical Specification & Design Documents
> Expert guidance for writing effective technical design documents, RFCs, Architecture Decision Records, and technology evaluation frameworks.
## Core Philosophy
- **Write before code** — Design documents prevent costly rework and align teams
- **Living documents** — Keep docs updated as the system evolves
- **Clarity over completeness** — Simple, direct language reduces cognitive load
- **Diagrams as code** — Version-controlled, maintainable architecture diagrams
- **Decisions over descriptions** — Document why, not just what
