Standards for Feign clients and asynchronous messaging with Spring Cloud Stream.

  • Implementing Feign HTTP clients

  • Async event messaging in Spring Boot microservices

What it does

Spring Boot Microservices is an agent skill from HoangNguyen0403/agent-skills-standard. Standards for Feign clients and asynchronous messaging with Spring Cloud Stream. Use when implementing Feign HTTP clients or async event messaging in Spring Boot microservices.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Backend & APIs, covering Backend development and Microservices. It works with Spring Boot. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Implementing Feign HTTP clients
  • Async event messaging in Spring Boot microservices

Example prompts

  • “Use the spring-boot-microservices skill to standard for Feign clients and asynchronous messaging with Spring Cloud Stream”
  • “/spring-boot-microservices”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spring Boot Microservices loads about 502 tokens when it runs, and up to ~949 if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 178 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~502
With references · SKILL.md plus every file in references/, read only if the agent opens them
~949

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Spring Boot Microservices Standards

Priority: P0 (CRITICAL)

Implementation Guidelines

Sync Communication (REST & API Interface)
  • Clients: Use Spring Cloud OpenFeign or HTTP Interfaces (Spring 6/Java 21).
  • Resilience: Implement Resilience4j with Circuit Breaker, Retry (Exponential Backoff), and RateLimiter.
  • Contracts: Share DTO Records via Maven BOM or API Contract module.
  • Tracing: Ensure Micrometer propagation for Distributed Tracing.

See implementation examples for Feign client with Circuit Breaker fallback.

Async Communication (Spring Cloud Stream)
  • Architecture: Use Message-Driven patterns with Spring Cloud Stream.
  • Functions: Define message handlers as java.util.function.Function, Consumer, or Supplier.
  • Serialization: Use JSON or Avro for events.
  • Reliability: Implement Dead Letter Queues (DLQ) and idempotent consumers.

See implementation examples for Spring Cloud Stream event consumer with idempotency.

Data & Isolation
  • DB per Service: NEVER share databases between microservices.
  • Shared Libs: Minimize shared logic to shared DTOs/Clients only.
  • Discovery: Use Spring Cloud Gateway for routing and auth.

Anti-Patterns

  • No Shared DB: Services must communicate via APIs or Events only.
  • No Shared Entities: Share DTOs via Maven BOM, never JPA entities.
  • No Sync Call Chains: Use async messaging to prevent distributed monolith.
