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 | $0.00018 | $0.00960 |
| Opus 5.5 | $0.00007 | $0.00384 |
| Sonnet 5.5 | $0.00004 | $0.00192 |
| Haiku 4.5 | $0.00002 | $0.00096 |
Grade A, and why
kotlin-springboot 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 1mo 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.

Spring Boot with Kotlin Best Practices
Your goal is to help me write high-quality, idiomatic Spring Boot applications using Kotlin.
Project Setup & Structure
- Build Tool: Use Maven (
pom.xml) or Gradle (build.gradle) with the Kotlin plugins (kotlin-maven-pluginororg.jetbrains.kotlin.jvm). - Kotlin Plugins: For JPA, enable the
kotlin-jpaplugin to automatically make entity classesopenwithout boilerplate. - Starters: Use Spring Boot starters (e.g.,
spring-boot-starter-web,spring-boot-starter-data-jpa) as usual. - Package Structure: Organize code by feature/domain (e.g.,
com.example.app.order,com.example.app.user) rather than by layer.
Dependency Injection & Components
- Primary Constructors: Always use the primary constructor for required dependency injection. It's the most idiomatic and concise approach in Kotlin.
- Immutability: Declare dependencies as
private valin the primary constructor. Prefervalovervareverywhere to promote immutability. - Component Stereotypes: Use
@Service,@Repository, and@RestControllerannotations just as you would in Java.
Configuration
- Externalized Configuration: Use
application.ymlfor its readability and hierarchical structure. - Type-Safe Properties: Use
@ConfigurationPropertieswithdata classto create immutable, type-safe configuration objects. - Profiles: Use Spring Profiles (
application-dev.yml,application-prod.yml) to manage environment-specific configurations. - Secrets Management: Never hardcode secrets. Use environment variables or a dedicated secret management tool like HashiCorp Vault or AWS Secrets Manager.
Web Layer (Controllers)
- RESTful APIs: Design clear and consistent RESTful endpoints.
- Data Classes for DTOs: Use Kotlin
data classfor all DTOs. This providesequals(),hashCode(),toString(), andcopy()for free and promotes immutability. - Validation: Use Java Bean Validation (JSR 380) with annotations (
@Valid,@NotNull,@Size) on your DTO data classes. - Error Handling: Implement a global exception handler using
@ControllerAdviceand@ExceptionHandlerfor consistent error responses.
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.

kotlin-springboot is a skill published in the GitHub repository boshi-xixixi/TraeSkill (277 stars, last pushed 5mo ago), licensed MIT. It adds 18 tokens to every session and 960 once invoked, about $0.0001 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 2026-09-03.
