kafka-streams-programming
Architect, build, and debug Kafka Streams apps (JVM-embedded stream processing). Use when user mentions KStream, KTable, topology, TopologyTestDriver, StreamsBuilder, interactive queries, GlobalKTable, joins/windows/aggregations, or debugging issues (rebalancing, state stores, lag, deserialization errors). Also use when user wants to optimize Kafka Streams for WarpStream or tune Kafka Streams client configuration for WarpStream. Do NOT trigger for Flink, connectors, CDC, or plain producer/consumer.
Install
With your agent
Install OMGSkills skill "confluentinc/agent-skills:skills/kafka-streams-programming" 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/kafka-streams-programming ~/.claude/skills/kafka-streams-programmingFrom README
Kafka Streams — Architect, Build, Debug JVM-embedded stream processing library with no separate cluster. ⚠️ IMPORTANT: Lazy-Load References Only Do NOT read all reference files upfront. Read ONLY what you need, when you need it. User asks "how do I join two topics?" → Read references/topology-patterns.md § Joins Decision Tree only User asks "build me a Kafka Streams app" → Read references/build-templates.md when writing build files, not before User asks "my app is crashing" → Read the specific section in references/debugging.md for that symptom Most questions need 0-2 reference files total, not all 10 Never read multiple files preemptively "just in case" Always Confirm Target Environment First Before answering in any mode (Architect, Build, Debug), confirm the target environment if the user hasn't stated it: Apache Kafka | Confluent Platform | Confluent Cloud | WarpStream.
