developing-kafka-java-client
Use when the user wants to integrate a Kafka client into an existing application or scaffold a Java Kafka client project (Maven or Gradle based) for Confluent Cloud, local Docker, or WarpStream. Covers the Apache Kafka Java clients (KafkaProducer/KafkaConsumer/KafkaShareConsumer) with Avro, JSON Schema, or Protobuf serializers. Also use when the user wants to optimize Java Kafka client configuration for WarpStream. Do NOT trigger for Kafka Streams apps (use kafka-streams-programming), Flink, connectors, or Kafka Python client (use developing-kafka-python-client).
Install
With your agent
Install OMGSkills skill "confluentinc/agent-skills:skills/developing-kafka-java-client" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/confluentinc/agent-skills /tmp/agent-skills && ln -s /tmp/agent-skills/skills/developing-kafka-java-client ~/.claude/skills/developing-kafka-java-clientFrom README
Confluent Kafka Java Client Creation Generate a production-ready Java project for producing to and/or consuming from Kafka using the Apache Kafka Java clients (KafkaProducer / KafkaConsumer) with Confluent Schema Registry serializers. Supports three target environments: Confluent Cloud (managed), Local Docker, and WarpStream (Kafka-compatible, object-storage-backed); two build tools: Maven (default) and Gradle; and three schema formats: Avro (default), JSON Schema, and Protobuf. The generated code follows Confluent's best practices. Step 1: Gather Requirements Before generating any code, work through the questions below. Skip any question the user has already answered explicitly in their prompt — do not re-ask just for form's sake. For example, "build a producer and consumer on Confluent Cloud with synchronous sends using Gradle" already answers #2, #3, #4, and #5; only #1, #6, #7, #8, #9, and #10 remain.
