Review spec.md requirements 2. Identify components and their responsibilities 3. Define data flow between components 4. Establish boundaries (APIs, databases, external services) 5. Document patterns and trade-offs ## Output Create `architecture.md` using the template in `templates/architecture.md`. ## Tips - Use Mermaid diagrams for visual clarity - Keep components single-responsibility - Consider existing patterns in the codebase - Document why decisions were made, not just what - Identify integration points with existing code --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/amattas) — claim your Tome and manage your conversions.
