What is spring-boot-scaffold CLAUDE.md?

Project instructions for working on a Spring Boot scaffold, a starter project for building Java web applications. They document how to build and run it with Maven, a Java build tool, including the included Maven wrapper and a helper script.

Building and running the project, using its Maven wrapper, checking common commands, and starting it with `./tool.sh boot-run`.

They keep an coding agent's commands aligned with the project's setup and avoid guessing how to start or build the application.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01962	$0.01962
Opus 5.5	$0.00785	$0.00785
Sonnet 5.5	$0.00392	$0.00392
Haiku 4.5	$0.00196	$0.00196

Security

Grade A, and why

spring-boot-scaffold CLAUDE.md 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 2mo 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.

Build and Run Commands

Maven Wrapper

This project uses Maven Wrapper. All Maven commands should use ./mvnw (or mvnw.cmd on Windows).

Common Commands

Build and test:

./mvnw clean install

Run tests only:

./mvnw test

Run a single test:

./mvnw test -Dtest=ClassName#methodName

Run application (via Spring Boot plugin):

cd spring-boot-scaffold-starter && mvn spring-boot:run

Or use the tool script:

./tool.sh -br
# or: ./tool.sh boot-run

Build and run packaged JAR:

./tool.sh -jr
# or: ./tool.sh jar-run
# Equivalent to: mvn clean install && java -jar spring-boot-scaffold-starter/target/spring-boot-scaffold-starter.jar

Deploy API module to remote repository:

./tool.sh -d
# or: ./tool.sh deploy

Generate Maven archetype from project:

./tool.sh -ga
# or: ./tool.sh generate-archetype

Docker commands:

# Build Docker image
./tool.sh -pi  # package-image

# Run container
./tool.sh -rc  # run-container

# Start with docker-compose
./tool.sh -dcu  # compose-up

# Stop docker-compose
./tool.sh -dcd  # compose-down

Spring Profiles

The application supports multiple profiles (configured in spring-boot-scaffold-starter/src/main/resources/):

dev (default): MySQL database on localhost:3306
local: H2 in-memory database for local development
docker: MySQL in Docker environment

Switch profiles:

mvn spring-boot:run -Dspring-boot.run.profiles=local

Or set in application.yml:

spring:
  profiles:
    active: local

Project Architecture

This is a multi-module Spring Boot application following Clean Architecture/Hexagonal Architecture principles with clear separation between layers.
