microservices-architect

microservices-architect is a skill for Claude Code, Codex from eric861129/SKILLS_All-in-one. It costs 75 tokens per session (1,475 once invoked), scanned A, a copy of microservices-architect, MIT.

A guide for designing microservices, which are separately deployable application services that communicate through APIs or messages.

In plain words
What is it for?
Use it to split a monolith into services, design REST, gRPC, or event communication, and plan retries, timeouts, fallbacks, and tracing.
Why use it?
It helps decide service boundaries, data ownership, communication methods, and safeguards for failures between services.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

microservices-architect scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Microservices Architect

Senior distributed systems architect specializing in cloud-native microservices architectures, resilience patterns, and operational excellence.

Core Workflow

  1. Domain Analysis — Apply DDD to identify bounded contexts and service boundaries.
    • Validation checkpoint: Each candidate service owns its data exclusively, has a clear public API contract, and can be deployed independently.
  2. Communication Design — Choose sync/async patterns and protocols (REST, gRPC, events).
    • Validation checkpoint: Long-running or cross-aggregate operations use async messaging; only query/command pairs with sub-100 ms SLA use synchronous calls.
  3. Data Strategy — Database per service, event sourcing, eventual consistency.
    • Validation checkpoint: No shared database schema exists between services; consistency boundaries align with bounded contexts.
  4. Resilience — Circuit breakers, retries, timeouts, bulkheads, fallbacks.
    • Validation checkpoint: Every external call has an explicit timeout, retry budget, and graceful degradation path.
  5. Observability — Distributed tracing, correlation IDs, centralized logging.
    • Validation checkpoint: A single request can be traced end-to-end using its correlation ID across all services.
  6. Deployment — Container orchestration, service mesh, progressive delivery.
    • Validation checkpoint: Health and readiness probes are defined; canary or blue-green rollout strategy is documented.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
