A Java and Maven plugin containing commands and skills for OpenRewrite code transformations, Maven POM dependency ordering, and Liquibase test-lock troubleshooting. Maven builds Java projects and manages their dependencies.

Use it to analyze or apply OpenRewrite rules, check POM ordering, follow safe Maven build practices, and resolve Liquibase lock failures.

It groups common Java-project maintenance and troubleshooting tasks into reusable coding-agent instructions.

Security

Grade A, and why

java 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 yesterday.

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 installs

The manifest is a name and a version. 7 skills, 3 commands, 1 agent travel with it, and installing the plugin installs all of them — 435 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
