Plugin Claude Code
Kora Framework development skill for building production-grade Java/Kotlin services — with compile-time DI, HTTP, Database, Kafka, gRPC, SOAP, OpenAPI, Telemetry, AOP. Zero reflection, zero proxies, AI agent friendly. For Kora version 1.x.
Skill Claude CodeCodex
Build and maintain Java/Kotlin services on the Kora Framework 1.x (ru.tinkoff.kora) — compile-time DI, zero reflection, annotation processors (Java) or KSP (Kotlin). Routes to 39 domain sub-skills. Use when the request mentions Kora, or uses Kora APIs: @KoraApp, @Component, @Module, @KoraSubmodule, @Root, @Tag…

Kora caching via compile-time AOP — @Cacheable/@CachePut/@CacheInvalidate over Caffeine (in-process) or Redis (distributed). Use when adding caching, choosing Caffeine vs Redis, or fixing "required keyPrefix" graph errors.
Skill Claude CodeCodex
Declarative method logging in Kora — @Log (+ @Log.in/out/result/off) and @Mdc via logging-common. Use when adding entry/exit logging, MDC context keys, or hiding sensitive arguments.
Skill Claude CodeCodex
Kora resilience aspects — @CircuitBreaker, @Retry, @Timeout, @Fallback (resilient-kora). Use when adding fault tolerance to outbound calls or tuning resilient. config keys.
Skill Claude CodeCodex
In-process scheduled jobs in Kora — @ScheduleAtFixedRate/@ScheduleWithFixedDelay/@ScheduleOnce (scheduling-jdk). Use for periodic/heartbeat/cleanup jobs; for cron or clustered jobs use kora-aop-scheduling-quartz.
Skill Claude CodeCodex
Quartz scheduling in Kora — @ScheduleWithCron, @ScheduleWithTrigger, @DisallowConcurrentExecution, @PersistJobDataAfterExecution (scheduling-quartz). Use for cron/custom-trigger/persistent jobs; for plain timers use kora-aop-scheduling-jdk.
Skill Claude CodeCodex
Kora declarative validation — @Valid/@Validate with Kora's own constraints (@NotBlank/@Pattern/@Range/@Size) and custom @ValidatedBy. Use when validating DTOs or service args. Kora validation is NOT Jakarta/JSR-380.
Skill Claude CodeCodex
HOCON typed config in Kora — @ConfigSource/@ConfigValueExtractor over application.conf via HoconConfigModule, with env substitution. Use when adding typed config or debugging "config value not found".
Skill Claude CodeCodex
YAML typed config in Kora — @ConfigSource/@ConfigValueExtractor over application.yaml via YamlConfigModule, with env substitution. Use when a service reads config from YAML instead of HOCON.
Skill Claude CodeCodex
Kora Cassandra/ScyllaDB repositories — @Repository extends CassandraRepository, @Query CQL, @EntityCassandra, @UDT, @Batch, per-method @CassandraProfile. Use when adding a Cassandra repository or mapping rows/UDTs.
Skill Claude CodeCodex
Kora JDBC repositories — @Repository extends JdbcRepository, @Query, @EntityJdbc, SQL macros, @Batch, transactions via inTx(), HikariCP under db. Use when adding a Postgres/MySQL/Oracle repository or debugging repository graph errors.
Skill Claude CodeCodex
Kora startup schema migrations — Flyway (FlywayJdbcDatabaseModule) or Liquibase (LiquibaseJdbcDatabaseModule). Use when wiring migrations into @KoraApp, choosing Flyway vs Liquibase, or fixing checksum/race failures.
Skill Claude CodeCodex
Compile-time DI in Kora — @KoraApp, @Component, @Module, @KoraSubmodule, @Root. Use when wiring the application graph or debugging "no factory found"/ambiguous/circular dependency errors. For runtime DI behavior see kora-di-runtime.
Skill Claude CodeCodex
Kora runtime DI behavior — @Root, Lifecycle init/release, @Tag disambiguation, All , ValueOf , @Nullable, GraphInterceptor. Use for lifecycle/collection/lazy/optional wiring. For compile-time @KoraApp/@Module wiring see kora-di-compile.
Skill Claude CodeCodex
Kora gRPC clients — GrpcClientModule with generated stubs injected as components, grpcClient. config, @Tag interceptors, streaming. Use when wiring an outbound gRPC call or adding gRPC metadata auth.
Skill Claude CodeCodex
Kora gRPC server handlers — GrpcServerModule, @Component extending the generated GrpcImplBase, ServerInterceptor, grpcServer config, reflection. Use when serving gRPC RPCs (unary/streaming) from a Kora service.
Skill Claude CodeCodex
Auth for outgoing Kora HTTP clients — Basic/ApiKey/Bearer interceptors, HttpClientTokenProvider, @InterceptWith, custom OAuth2/JWT schemes. Use when authorizing a @HttpClient or debugging 401s. For server-side auth see kora-http-server-auth.
Skill Claude CodeCodex
Declarative Kora HTTP clients — @HttpClient with @HttpRoute, @Path/@Query/@Header, @Json, interceptors, OkHttp/Async/JDK transports. Use for typed outbound calls. For OpenAPI clients see kora-openapi-generator-client; for the inbound server see kora-http-server.
Skill Claude CodeCodex
HTTP server auth in Kora — HttpServerPrincipalExtractor, Principal/PrincipalWithScopes, SecurityException→403 via interceptor. Use when securing @HttpController endpoints or integrating an OpenAPI security scheme. For client-side auth see kora-http-client-auth.
Skill Claude CodeCodex
Kora HTTP server controllers on Undertow — @HttpController, @HttpRoute, @Path/@Query/@Header, @Json, HttpResponseEntity, HttpServerInterceptor. Use when building REST endpoints or wiring UndertowHttpServerModule.
Skill Claude CodeCodex
Journal for incorrect Kora usage (korajournal.py add/search/integrate). Global shared store at /.kora-journal/. Use when you or the user find a wrong Kora annotation, hallucinated API, or misapplied pattern. Not for project business logic.
Skill Claude CodeCodex
Compile-time JSON in Kora — @Json generates JsonReader/JsonWriter for records/data classes; sealed discriminators, @JsonField/@JsonSkip, JsonNullable, custom factories, Jackson swap. Use for HTTP DTOs or polymorphic JSON.
