🏛️Backend Architect

By wshobson

Designs your backend architecture and API contracts before you build the services

What it does

What it does: Acts as a senior backend architect that makes design decisions contract-first and hands you concrete artifacts, not just advice.

  • Picks the right API paradigm (REST, gRPC, GraphQL, WebSocket) with trade-off rationale, then defines endpoints and generates OpenAPI 3.1 / AsyncAPI / Protobuf specs
  • Draws service boundaries from DDD bounded contexts and data ownership, and plans monolith decomposition with strangler-fig migration sequencing
  • Designs event-driven communication (Kafka, NATS, SQS), saga patterns for distributed transactions, and database schemas with indexes, sharding, and read replicas
  • Bakes in observability from day one: structured logging with trace IDs, OpenTelemetry tracing, RED-method metrics, health/ready/metrics endpoints, and SLO alert thresholds
  • Covers security per layer — OWASP API Top 10, JWT/RBAC at the gateway, mTLS between services, Vault-based secrets, and input validation at boundaries

Installation

  1. Make sure Claude is on your device and in your terminal.

    Agents load from ~/.claude/agents/ when Claude Code starts. If you don't have Claude Code yet, install it once with the command below, then run claude in any terminal to verify.

    One-time setup
    npm i -g @anthropic-ai/claude-code

    Already have it? Skip ahead.

  2. Paste into your terminal.
    Install
    Sign up to copy

    Downloads the agent into ~/.claude/agents/backend-architect-wshobson.md. Safe to re-run; it just overwrites.

  3. Restart Claude Code.

    Quit and reopen Claude Code. New agents are picked up on startup.

  4. Use it.

    Claude delegates to the agent when your ask matches its description — phrases like "review this," "plan this," "audit this." You can also invoke directly: "Use the backend-architect-wshobson agent to…"
