Docs Architecture

Docs Architecture

Maintain architecture-level docs without drifting into component internals or feature copy. Keep root and domain architecture docs aligned with the current topology and the docs they index.

Resource Map

• Use assets/doc-starters/architecture-doc.md when creating or substantially rewriting docs/ARCHITECTURE.md or a domain architecture doc such as web-architecture.md.
• Read references/architecture-example.md when you need a worked example of the expected level of abstraction.

When to Use

• New system boundary, pipeline stage, deployment model, or ownership boundary
• Changes to shared patterns used across multiple services or features
• Updates to architecture index docs that link to docs/designs/ or docs/features/
• Domain architecture docs describing reusable patterns, topology, or trust boundaries

Do Not Use

• Component or service implementation detail that belongs in docs-components-design
• Feature behavior, user flows, or product narrative that belongs in docs-feature-design

Workflow

1. Identify the target architecture doc and its scope.

• Root architecture doc for the whole system
• Domain architecture doc for a shared surface such as web, API, or data

1. Update only architecture-level content.

• System or domain boundaries
• Shared principles and patterns
• Cross-component data or control flow
• Runtime, deployment, trust boundaries, and ownership

1. Keep architecture docs as index docs.

• Link to related docs/designs/ and docs/features/ docs
• Summarize shared behavior instead of duplicating component internals

1. Verify truth-bearing details.

• Active components and boundaries match the current code
• Flows, contracts, and ownership are still accurate
• Security and operations notes reflect the live system

1. Trim stale detail.

• Remove implementation walkthroughs that belong in component docs
• Remove feature-level behavior copy that belongs in feature docs

Writing Rules

• Focus on topology, boundaries, and shared patterns
• Explain why the system is shaped this way, not every internal step
• Prefer concise diagrams and links over long prose dumps
• Treat the doc as an index and coordination surface, not a full implementation manual

Quality Checklist

• The doc clearly states its scope and boundaries
• Shared patterns and cross-component flows are current
• Links to related design and feature docs are synchronized
• Component-level internals are linked out instead of duplicated
• Security, operations, and ownership notes reflect current behavior
