architecture-diagrams

Overview

Visual architecture engineering skill inspired by tt-a1i/archify. Replaces static ASCII art and rigid default diagrams with crisp, self-contained SVG and responsive HTML diagrams featuring modern dark-mode palettes, pulse animations for event flows, and strict C4-model component boundaries.

When to Use

Activate whenever:

• Designing or explaining distributed systems, microservices, or full-stack architectures.
• Visualizing complex auth flows (OAuth2, PKCE), multi-step payment sagas, or CDC outbox data pipelines.
• User requests an architecture diagram, flow chart, sequence diagram, or visual system design.

Rules & Patterns

1. Diagram Types Supported

1. System Landscape / C4 Container Diagram:
   • Clients (Web, Mobile, Third-party) → API Gateway / CDN → Microservices / Serverless → Storage / Event Brokers.
2. Sequence Flow Diagram:
   • Step-by-step lifecycles with synchronous requests, asynchronous pub/sub events, and compensating transactions.
3. Data Pipeline & Event-Driven Topology:
   • Primary DB → Transactional Outbox → CDC (Debezium) → Kafka Topic → Consumers → Materialized Views.

2. Aesthetic & Visual Invariants

• Dark Theme by Default: Surface #0B0F19, containers #1E293B, borders #334155, text #F8FAFC.
• Semantic Component Accents:
  • Client / Frontend: Sky Blue (#38BDF8)
  • API Gateway / Router: Indigo (#818CF8)
  • Business Services: Emerald Green (#34D399)
  • Databases / Storage: Amber / Orange (#F59E0B)
  • Message Brokers / Event Buses: Purple (#A855F7)
• Active Data-Flow Motion: Use subtle CSS @keyframes on SVG stroke dashes (stroke-dasharray, stroke-dashoffset) to show active direction of messages and data streams.
