What it does
Spring Boot Skill is an agent skill from piomin/sample-spring-modulith. Build Spring Boot 4.x applications following the best practices. Use these guidelines when developing Spring Boot applications that use Spring MVC, Spring Data JPA, Spring Modulith, Spring Security. Use these guidelines to create recommended Spring Boot package structure. Use these best practices while implementing REST APIs, entities/repositories, service layer, modular monoliths. Use these guidelines while writing tests for REST APIs and Web applications. Configure the recommended plugins and configurations to…
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `references/code-organization.md`, `references/spring-boot-docker-compose.md` and `references/spring-boot-maven-config.md`).
It sits in Backend & APIs, covering Backend development, REST APIs and Containers. It works with Spring Boot and Docker. The repository describes itself as: The demo repository showing modulith architecture with Spring Boot and Spring Modulith.
When your agent uses it
- Tasks that involve Backend development
- Tasks that involve REST APIs
- Tasks that involve Containers
Example prompts
- “/spring-boot-skill”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit ee54cdc. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spring Boot Skill loads about 668 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 194 tokens; SKILL.md has 158 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 158 words (~668 tokens).
“Apply the practices below when developing Spring Boot applications. Read the linked reference only when working on that area.”
