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.

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 | $0.00063 | $0.00757 |
| Opus 5 | $0.00032 | $0.00378 |
| Sonnet 5 | $0.00013 | $0.00151 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
evo-spring-boot-jakarta-migration 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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spring Boot 2.7 → 3.2 Jakarta Migration Skill
Purpose
Migrate a Java 8/Spring Boot 2.7 user management microservice to Java 21/Spring Boot 3.2, covering all layers of the application stack.
Key Migration Areas
- pom.xml: Update parent to 3.2.x, java.version to 21, maven-compiler-plugin with
-parameters, replace jjwt 0.9.x with modular 0.12.x, remove jaxb-api - Jakarta namespace: Replace javax.persistence → jakarta.persistence, javax.validation → jakarta.validation, javax.servlet → jakarta.servlet. Preserve javax.crypto, javax.sql, javax.net (Java SE packages)
- Spring Security 6: Remove WebSecurityConfigurerAdapter, use SecurityFilterChain bean, Lambda DSL, authorizeHttpRequests + requestMatchers, @EnableMethodSecurity
- JJWT 0.12.x API: Migrate from
Jwts.parser().setSigningKey()toJwts.parser().verifyWith().build().parseSignedClaims(), fromJwts.builder().signWith(SignatureAlgorithm.HS512, key)toJwts.builder().signWith(key) - Hibernate 6: Remove versioned dialect references, use GenerationType.IDENTITY explicitly, update H2Dialect to unversioned form
- RestTemplate → RestClient: Migrate to fluent RestClient API
- Application properties: Update hibernate dialect class names, remove deprecated properties
Usage

What ships with it
3 files 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.
