Microservice Defaults

Default microservice requirements in application/ (Kotlin, Spring Boot, jOOQ, generated REST/Kafka DTO, Feign, logging, 70% tests). Read reference.md first; do not explore repo. Use for create/update/review in application/ unless user overrides.

Microservice defaults

When to apply

Tasks in application/<group>/<service>/ unless user overrides in prompt.

Contracts: documentation/specifications/microservices/.... Patterns: reference.md. Open currencies-crud only if asked or new pattern.

Workflow (no re-exploration)

Read reference.md — do not explore repo.
Read target spec: documentation/specifications/microservices/<group>/<service>/.
ADR from documentation/ADR/index.md if needed (topic only).
If service exists — read only application/<group>/<service>/.
Implement per below + rule microservice-implementation.mdc.

Requirements

Stack: kotlin, spring-boot, kafka, postgres
jOOQ: generated com.vimpishsnorfle.jooq:*; no raw SQL; prefer DSL close to SQL, avoid imperative query assembly
REST: generated com.vimpishsnorfle.rest:* DTO and *Api
Kafka: generated com.vimpishsnorfle.messaging:*
Outbound REST: OpenFeign + com.vimpishsnorfle.rest DTO/interfaces
Logging (SLF4J/logback): log key decisions and outcomes; traceable what/why
Tests: ≥70% line coverage (jacoco)
DRY, SRP

Patterns

REST/Feign: controller implements *Api; Feign interface Client : V1*ControllerApi — no manual OpenAPI duplicates.

Kafka: Consumer<Message<Dto>> or generated consumer; producer uses messaging DTO.

Tests: jacoco 0.70 on check; database-test + Testcontainers — see reference.md.

Logging: LoggerFactory.getLogger(javaClass); info decisions/outcomes, debug inputs/steps, warn/error with entity ids + cause.

Deviations

If blocked (missing artifact, jOOQ table, etc.) and user did not allow — stop; state need: schema/migration/artifact or explicit prompt permission.
