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 | $0.00098 | $0.01446 |
| Opus 5.5 | $0.00039 | $0.00578 |
| Sonnet 5.5 | $0.00020 | $0.00289 |
| Haiku 4.5 | $0.00010 | $0.00145 |
Grade A, and why
spring-boot-verify 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spring Boot 4.x Project Verification
Analyzes Spring Boot projects for dependency compatibility, configuration correctness, and migration readiness.
Verification Workflow
- Detect Build System → Find pom.xml or build.gradle, extract Spring Boot version
- Analyze Dependencies → Check versions, find deprecated libraries, validate compatibility
- Validate Configuration → Check application.yml/properties, security config, actuator settings
- Generate Report → Structured markdown with severity levels and remediation code
- Lookup Docs → Use Exa MCP to fetch latest Spring Boot 4.x documentation when needed
Dependency Quick Reference
| Check | Severity | Action |
|---|---|---|
| Spring Boot version < 4.0 | CRITICAL | Upgrade to 4.0.x |
Jackson 2.x (com.fasterxml) |
CRITICAL | Migrate to Jackson 3 (tools.jackson) |
javax.* imports |
CRITICAL | Migrate to jakarta.* namespace |
@MockBean in tests |
ERROR | Replace with @MockitoBean |
| Undertow server | ERROR | Switch to Tomcat or Jetty |
| Java version < 17 | ERROR | Minimum Java 17 required |
| Gradle version < 8.14 | ERROR | Upgrade Gradle (required for Kotlin 2.2/Boot 4) |
spring-boot-starter-web |
WARNING | Use spring-boot-starter-webmvc |
| Missing Virtual Threads | INFO | Enable with spring.threads.virtual.enabled=true |
Configuration Quick Reference
| Check | Severity | Action |
|---|---|---|
Security and() chaining |
CRITICAL | Convert to Lambda DSL closures |
antMatchers() usage |
ERROR | Replace with requestMatchers() |
authorizeRequests() |
ERROR | Replace with authorizeHttpRequests() |
| All actuator endpoints exposed | WARNING | Limit to health, info, metrics |
| 100% trace sampling | WARNING | Use 10% in production |
Jakarta Namespace Migration
Critical for Spring Boot 3+: All javax.* packages must migrate to jakarta.*:
| Old Package | New Package |
|---|---|
javax.persistence.* |
jakarta.persistence.* |
javax.servlet.* |
jakarta.servlet.* |
javax.validation.* |
jakarta.validation.* |
javax.inject.* |
jakarta.inject.* |
javax.annotation.* |
jakarta.annotation.* |
What ships with it
6 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.

spring-boot-verify is a skill published in the GitHub repository joaquimscosta/arkhe-claude-plugins (21 stars, last pushed yesterday), licensed MIT. It adds 98 tokens to every session and 1,446 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-16.
