Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00154 | $0.01223 |
| Opus 5 | $0.00077 | $0.00611 |
| Sonnet 5 | $0.00031 | $0.00245 |
| Haiku 4.5 | $0.00015 | $0.00122 |
Grade A, and why
jdtls-lombok-fix 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
jdtls-lombok-fix
Claude Code's jdtls-lsp plugin starts Eclipse JDT LS without the Lombok
javaagent. Lombok's compile-time magic (@Slf4j, @Getter, @Builder,
@RequiredArgsConstructor, @Data, …) never gets applied inside JDTLS, so
every Lombok-using class lights up with false errors in the language server's
diagnostics — while Maven/Gradle compile just fine because they have Lombok
on the annotation-processor path.
The noise is indistinguishable from real compile errors unless you know the
fingerprint, and it distracts from actual code review. This skill applies the
workaround documented in
https://github.com/anthropics/claude-plugins-official/issues/1000:
patch the official plugin marketplace's marketplace.json so that jdtls-lsp
starts JDTLS with --jvm-arg=-javaagent:<lombok.jar>.
Preconditions
Run this ONLY when both are true:
- You've seen one or more diagnostics matching the Lombok fingerprint below.
- The build tool is not also reporting those errors. If you haven't run a
build recently, run the project's normal build command (
./mvnw compile,./gradlew compileJava, etc.) and confirm it succeeds. If it fails, the errors are real — do NOT apply this patch; fix the code instead.

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.

jdtls-lombok-fix is a skill published in the GitHub repository SkillPanel/claude-plugins (3 stars, last pushed 4mo ago), licensed MIT. It adds 154 tokens to every session and 1,223 once invoked, about $0.0008 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 2026-08-31.
