Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.00469 |
| Opus 5 | $0.00056 | $0.00234 |
| Sonnet 5 | $0.00022 | $0.00094 |
| Haiku 4.5 | $0.00011 | $0.00047 |
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 7d 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 compileormvn compilebefore applying any change - SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verifyormvn clean verifyafter 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
- Read reference and assess project context
Read references/314-frameworks-spring-kafka.md and inspect current messaging setup before proposing changes.
- Gather scope and decide target improvements
Identify reliability and throughput goals and define the minimum safe set of changes.
- Apply framework-aligned changes
Implement/refactor Spring Kafka configuration, producer/consumer logic, and failure handling.
- Run verification and report results
Execute build/tests and summarize what changed, what was verified, and follow-up actions.

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.
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.

314-frameworks-spring-kafka is a skill published in the GitHub repository jabrena/plinth (438 stars, last pushed yesterday), licensed Apache-2.0. It adds 112 tokens to every session and 469 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
