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 | $0.00091 | $0.01460 |
| Opus 5.5 | $0.00036 | $0.00584 |
| Sonnet 5.5 | $0.00018 | $0.00292 |
| Haiku 4.5 | $0.00009 | $0.00146 |
Grade A, and why
java-service-layer 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.

Java Service 层开发规范
快速开始
生成 Service 层代码的基本步骤:
- 定义 Service 接口(使用
assets/ServiceInterfaceTemplate.java) - 实现 Service 接口(使用
assets/ServiceImplTemplate.java) - 配置事务管理(见 references/transaction-management.md)
- 封装业务逻辑(见 references/business-logic-patterns.md)
接口与实现分离
规范要求
- 定义 Service 接口(Interface)
- 实现类使用
@Service注解 - 接口命名:
XxxService - 实现类命名:
XxxServiceImpl
代码模板
参考 assets/ServiceInterfaceTemplate.java 和 assets/ServiceImplTemplate.java 模板文件。
依赖注入最佳实践
1. 优先使用构造函数注入
@Service
@RequiredArgsConstructor // Lombok 自动生成构造函数
public class UserServiceImpl implements UserService {
private final UserRepository userRepository; // final 字段,不可变
private final EmailService emailService;
// 依赖明确且可测试,无需 Spring 上下文即可实例化
}
优势:
- ✅ 依赖明确且不可变(
final字段) - ✅ 可测试性强,无需 Spring 上下文即可实例化
- ✅ IDE 友好,依赖关系清晰
- ✅ 线程安全
2. 处理可选依赖
@Service
@RequiredArgsConstructor
public class NotificationService {
private final EmailProvider emailProvider;
private SmsProvider smsProvider; // 可选依赖
public NotificationService(EmailProvider emailProvider) {
this.emailProvider = Objects.requireNonNull(emailProvider);
}
@Autowired(required = false)
public void setSmsProvider(SmsProvider smsProvider) {
this.smsProvider = smsProvider;
}
public void notify(User user, String message) {
emailProvider.send(user.getEmail(), message);
if (smsProvider != null) {
smsProvider.send(user.getPhone(), message);
}
}
}
3. 使用 @Qualifier 解决 Bean 歧义
@Service
@RequiredArgsConstructor
public class PaymentService {
@Qualifier("stripePaymentGateway")
private final PaymentGateway paymentGateway;
public PaymentResult processPayment(PaymentRequest request) {
return paymentGateway.charge(request);
}
}
4. 避免字段注入
// ❌ 不推荐:字段注入
@Service
public class UserService {
@Autowired
private UserRepository userRepository; // 难以测试,依赖不明确
}
// ✅ 推荐:构造函数注入
@Service
@RequiredArgsConstructor
public class UserService {
private final UserRepository userRepository; // 明确且可测试
}
What ships with it
4 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.

java-service-layer is a skill published in the GitHub repository lambert0529/skills (11 stars, last pushed 9mo ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,460 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 2026-08-30.
