microservices-patterns

microservices-patterns is a skill for Claude Code from wshobson/agents. It costs 38 tokens per session (428 once invoked), scanned A, original, MIT.

A guide to microservices, an architecture where an application is split into independently managed services. It covers service boundaries, communication, data ownership, event-driven design, and resilience.

In plain words
What is it for?
Use it when decomposing a monolith, defining service contracts, choosing REST, gRPC, GraphQL, or messaging, and designing discovery, load balancing, and recovery.
Why use it?
It helps teams break apart large applications while managing the communication, data consistency, and failures that arise between services.

About the project

Agentic Plugin Marketplace is a collection of reusable plugins, agents, skills, commands, and rules for coding-agent tools including Claude Code, Codex CLI, Cursor, OpenCode, Antigravity CLI, and GitHub Copilot. It is for developers assembling agentic workflows across multiple harnesses from shared Markdown sources, and the catalogue entries are examples or subsets of those workflow components.

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-patterns scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Microservices Patterns

Master microservices architecture patterns including service boundaries, inter-service communication, data management, and resilience patterns for building distributed systems.

When to Use This Skill

  • Decomposing monoliths into microservices
  • Designing service boundaries and contracts
  • Implementing inter-service communication
  • Managing distributed data and transactions
  • Building resilient distributed systems
  • Implementing service discovery and load balancing
  • Designing event-driven architectures

Core Concepts

1. Service Decomposition Strategies

By Business Capability

  • Organize services around business functions
  • Each service owns its domain
  • Example: OrderService, PaymentService, InventoryService

By Subdomain (DDD)

  • Core domain, supporting subdomains
  • Bounded contexts map to services
  • Clear ownership and responsibility

Strangler Fig Pattern

  • Gradually extract from monolith
  • New functionality as microservices
  • Proxy routes to old/new systems

2. Communication Patterns

Synchronous (Request/Response)

  • REST APIs
  • gRPC
  • GraphQL

Asynchronous (Events/Messages)

  • Event streaming (Kafka)
  • Message queues (RabbitMQ, SQS)
  • Pub/Sub patterns

3. Data Management

Database Per Service

  • Each service owns its data
  • No shared databases
  • Loose coupling

Saga Pattern

  • Distributed transactions
  • Compensating actions
  • Eventual consistency

4. Resilience Patterns

Circuit Breaker

  • Fail fast on repeated errors
  • Prevent cascade failures

Retry with Backoff

  • Transient fault handling
  • Exponential backoff

Bulkhead

  • Isolate resources
  • Limit impact of failures

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

microservices-patterns is a skill published in the GitHub repository wshobson/agents (39,428 stars, last pushed 4d ago), licensed MIT. It adds 38 tokens to every session and 428 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
