setup

A setup tool that adds shared Spring Boot and JPA guardrails to a project. JPA is the Java layer commonly used to map application objects to database tables.

In plain words
What is it for?
Use it to install project hooks, rules, a Spring Boot reviewer, and documented conventions for entities, database migrations, and related backend code.
Why use it?
It gives the whole team the same checks for common backend mistakes, including missing optimistic locking, broken transactions, data access leaks, inefficient queries, and unsafe query construction.

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

setup 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 2d 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spring Boot Toolkit — Setup

Installs the enforcement layer into the project's .claude/ so it is committed and shared with the whole team — a teammate who clones the repo gets the guardrails even without installing this plugin. The authoring skills (jpa-entity, spring-rest-endpoint, db-migration) stay plugin-provided and are not copied.

Plugin source root (where templates live): the directory containing this skill's parent, i.e. plugins/java-backend-toolkit/. Resolve files relative to it.

Step 1 — Verify this is a Spring Boot + JPA project

Confirm at least one of:

  • pom.xml containing spring-boot-starter, or
  • build.gradle / build.gradle.kts containing spring-boot.

And JPA in use: spring-boot-starter-data-jpa (or jakarta.persistence / javax.persistence imports).

If not a Spring Boot + JPA project → stop and say so. This toolkit's v1 paved road is Spring Boot 3.x + Spring Data JPA only (no Kotlin, reactive, or non-Spring).

Step 2 — Detect project slots (smart defaults, confirm — do not interrogate)

Scan, propose, ask only to confirm:

Slot Detect from Default if absent
MIGRATION_TOOL flyway-core dep or src/main/resources/db/migration/ → Flyway; liquibase-core → Liquibase Flyway
BASE_ENTITY a @MappedSuperclass class and/or AuditingEntityListener usage a @MappedSuperclass BaseEntity with Spring Data JPA auditing
PROJECT_NAME CLAUDE.md identity / repo dir name repo directory name
strict mode --strict arg jpql-injection blocks (already the default in guardrails-config.json)

Show the resolved slot values in one block and get a single confirmation.

Step 3 — Install the guardrail hook (copy flat into .claude/hooks/)

Copy these three files from the plugin's hooks/ and rules/ into the project's .claude/hooks/ (flat — the hook finds its ruleset beside itself):

  • hooks/jpa-guardrail.py.claude/hooks/jpa-guardrail.py
  • rules/ruleset.json.claude/hooks/ruleset.json
  • hooks/guardrails-config.json.claude/hooks/guardrails-config.json

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.

setup is a skill published in the GitHub repository ShipWithAI/shipwithai-plugins (10 stars, last pushed 20d ago), licensed MIT. It adds 99 tokens to every session and 1,392 once invoked, about $0.0005 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.
