Microservices Architecture

Use this parent skill as the active microservices entrypoint. It should help decide whether microservices are justified, then shape service boundaries and operating contracts when they are.
Use When
- Defining service boundaries, ownership, API contracts, data ownership, deployment independence, or migration from a monolith.
- Reviewing synchronous and asynchronous service communication, reliability, retries, idempotency, and failure isolation.
- Creating a target architecture for teams that need multiple independently deployable backend services.
Do Not Use When
- The task is unrelated to this parent skill or is better handled by a narrower active parent named in the workflow.
- The request only needs a trivial answer and no reference module needs to be loaded.
Required Inputs
- Gather the concrete system, repository, environment, constraints, and deliverable before loading references.
- Identify which absorbed reference file is needed; do not load every migrated reference by default.
Workflow
- Start with
system-architecture-design and distributed-systems-patterns for context, constraints, and failure modes.
- Load only the needed reference:
references/microservices-fundamentals.md for core principles and when not to split.references/microservices-architecture-models.md for decomposition and ownership models.references/microservices-communication.md for API, event, queue, and contract patterns.references/microservices-resilience.md for retries, circuit breakers, idempotency, and graceful degradation.
- Pair with
api-design-first, database-design-engineering, deployment-release-engineering, and observability-monitoring for implementation contracts.
Quality Standards
- Do not split services without a clear ownership, deployment, data, and reliability reason.
- Every service boundary must define source of truth, API contract, failure mode, observability, and rollback path.
- Prefer fewer services until team topology, data ownership, and release cadence justify more.
Anti-Patterns
- Treating absorbed reference files as active skills or separate routing entrypoints.
- Loading every migrated child reference instead of the one that matches the task.
- Producing generic advice without constraints, evidence, or next verification steps.
Outputs
- Service map, boundary decision, API/event contract notes, migration plan, or architecture review.
References
- Load only the
eferences/.md files named in the workflow when their depth is required.
