314-frameworks-spring-kafka

314-frameworks-spring-kafka is a skill for Claude Code, Codex from jabrena/plinth. It costs 112 tokens per session (469 once invoked), scanned A, original, Apache-2.0.

A guide for building Kafka messaging in Spring Boot. Kafka is a system where applications publish messages to named streams, called topics, and other applications consume them later.

In plain words
What is it for?
Use it to design topics, implement producers and consumers, configure JSON messages, add retries and dead-letter topics, and test Kafka flows with containers.
Why use it?
It helps make message delivery more reliable by addressing retries, duplicate processing, serialization, and messages that cannot be handled.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

314-frameworks-spring-kafka scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Spring Boot — Kafka messaging

Apply Spring Kafka guidance with concrete examples for design, implementation, and error handling.

Constraints

Compile before messaging refactors; verify after changes.

  • MANDATORY: Run ./mvnw compile or mvn compile before applying any change
  • SAFETY: If compilation fails, stop immediately
  • VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
  • BEFORE APPLYING: Read the reference for detailed rules and examples

When to use this skill

  • Add Kafka in Spring Boot
  • Review Spring Kafka consumers/producers
  • Improve retries, dead-letter topics, or idempotency in Spring Kafka
  • Configure Spring Kafka topics serializers or listener containers
  • Add Spring Kafka dead-letter topic handling

Workflow

  1. Read reference and assess project context

Read references/314-frameworks-spring-kafka.md and inspect current messaging setup before proposing changes.

  1. Gather scope and decide target improvements

Identify reliability and throughput goals and define the minimum safe set of changes.

  1. Apply framework-aligned changes

Implement/refactor Spring Kafka configuration, producer/consumer logic, and failure handling.

  1. Run verification and report results

Execute build/tests and summarize what changed, what was verified, and follow-up actions.

Reference

For detailed guidance, examples, and constraints, see references/314-frameworks-spring-kafka.md.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
