Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00090 | $0.00672 |
| Opus 5 | $0.00045 | $0.00336 |
| Sonnet 5 | $0.00018 | $0.00134 |
| Haiku 4.5 | $0.00009 | $0.00067 |
Grade A, and why
300-frameworks-spring-boot-create-project 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 5d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Spring Boot Maven Project
Create a new Spring Boot Maven project through SDKMAN-managed tooling, aligned with Java 25 and the repository's Spring Boot 4.0.x baseline.
What is covered in this Skill?
- Verify SDKMAN and Java availability before project creation
- Install or select the required Java and Spring Boot CLI candidates through SDKMAN
- Gather project coordinates, package name, Java version, packaging, and dependencies
- Create a Maven project with Spring Initializr-backed Spring Boot CLI commands
- Prefer Maven wrapper commands for validation
- Verify the generated project with Maven before reporting completion
Constraints
Project creation must be explicit, reproducible, and Maven-based.
- PREREQUISITE: Verify SDKMAN is installed with
sdk version; if missing, stop and provide setup guidance instead of installing it silently - JAVA BASELINE: Prefer Java 25 unless the user requests another supported version
- FRAMEWORK BASELINE: Target Spring Boot 4.0.x by default
- BUILD TOOL: Generate a Maven project, not Gradle
- SAFETY: Do not overwrite an existing non-empty target directory without explicit user confirmation
- VERIFY: Run
./mvnw clean verifyfrom the generated project when the Maven wrapper exists; otherwise runmvn clean verify - BEFORE APPLYING: Read the reference for the full SDKMAN and Spring Boot CLI workflow
When to use this skill
- Create a Spring Boot Maven project
- Bootstrap Spring Boot project with SDKMAN
- Generate a new Spring Boot service
- Create Spring Boot 4 Maven project
- Scaffold Spring Boot service with Java 25
Workflow
- Read reference and gather project inputs
Read references/300-frameworks-spring-boot-create-project.md, then gather project directory, group, artifact, package name, Java version, packaging, and initial dependencies.
- Verify SDKMAN-managed tooling
Check SDKMAN, Java, and Spring Boot CLI availability. Install or switch candidates only after confirming the intended versions with the user.
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.
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.

300-frameworks-spring-boot-create-project is a skill published in the GitHub repository jabrena/plinth (436 stars, last pushed 3d ago), licensed Apache-2.0. It adds 90 tokens to every session and 672 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 2026-09-03.
