system-design-doc

A system design doc captures architecture, data flows, service boundaries, and deployment topology for cross-domain initiatives. You need one for multi-service design initiatives to ensure alignment and document operational considerations like failure modes and security.

Generate system design documentation by running a plan-driven workflow that scaffolds the doc structure, gathers deep context, fills in architecture and data flow sections, audits, validates, and syncs results to a living plan file.

The best way to structure a system design doc is using a template with mandatory frontmatter that captures architecture diagrams, service boundaries, invariants, failure modes, deployment topology, and security considerations in a single spec linked to a living plan.

Yes, the system design doc workflow requires plan linkage. It scaffolds documents using a plan-driven template and syncs the filled, audited, and validated results back to the living plan file.

Yes, the system design doc template is specifically applicable to cross-domain initiatives requiring multi-service design. It captures service boundaries, data flows, and operational considerations to align engineering teams across domains.

Mandatory sections include architecture, service boundaries, data flows, invariants, failure modes, deployment topology, and security considerations. The template enforces mandatory frontmatter and requires plan linkage to maintain document structure.
