shipwithai-java-backend-toolkit

A Claude Code toolkit for Spring Boot, a Java framework for web applications, and JPA, the standard Java approach for working with database records. It combines coding guardrails, code scaffolding, and a review agent.

In plain words
What is it for?
Use it to set up project guardrails and create JPA entities, REST endpoints, database migrations, authentication, security configuration, error handling, idempotent endpoints, and tests.
Why use it?
It helps catch backend design and security mistakes while code is being written and keeps the generated code aligned with the project's rules.

Grade A, and why

shipwithai-java-backend-toolkit 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 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.
