SLF4J - Simple Logging Facade for Java. Standard logging API that abstracts underlying implementation (Logback, Log4j2). Provides parameterized logging and MDC support. USE WHEN: user mentions "slf4j", "java logging api", "parameterized logging", asks about "how to log in Java", "logger facade", "MDC in java", "logging best practices java" DO NOT USE FOR: Logback configuration - use `logback` instead, Log4j2 configuration - use Log4j2 skill, Node.js logging - use `winston` or `pino` instead, Python logging - use `python-logging` instead
Java logging with SLF4J facade, Logback, and Log4j2 implementations. Covers configuration, log levels, structured logging, async logging, and production best practices for Spring Boot applications. USE WHEN: user mentions "java logging", "spring boot logging", "slf4j setup", asks about "how to log in java", "logback vs log4j2", "java logging best practices" DO NOT USE FOR: Node.js logging - use `nodejs-logging` instead, Python logging - use `python-logging`, Kotlin-specific logging - similar but has nuances
Use when you need to implement or improve Java logging and observability — including selecting SLF4J with Logback/Log4j2, applying proper log levels (ERROR, WARN, INFO, DEBUG, TRACE), parameterized logging, secure logging without sensitive data exposure, environment-specific configuration, log aggregation and monitoring, or validating logging through tests. Part of the skills-for-java project
Java logging best practices with SLF4J, structured logging (JSON), and MDC for request tracing. Includes AI-friendly log formats for Claude Code debugging. Use when user asks about logging, debugging application flow, or analyzing logs.
Use when you need to implement or improve Java logging and observability — including selecting SLF4J with Logback/Log4j2, applying proper log levels (ERROR, WARN, INFO, DEBUG, TRACE), parameterized logging, secure logging without sensitive data exposure, environment-specific configuration, log aggregation and monitoring, or validating logging through tests. This should trigger for requests such as Improve logging; Apply logging; Refactor logging; Add logging support. Part of cursor-rules-java project
structlog - structured logging library for Python with native JSON support, context binding, and processor pipeline. Integrates with FastAPI, Django, and standard logging module. USE WHEN: user mentions "structlog", "python structured logging", "context binding", asks about "JSON logging python", "fastapi logging", "django structured logging" DO NOT USE FOR: Standard Python logging - use `python-logging` instead, Node.js logging - use `pino` or `winston`, Java logging - use `slf4j` or `logback` instead
Logback - flexible and powerful logging framework for Java and Spring Boot applications. Successor to Log4j with native SLF4J support, async logging, and automatic file rotation. USE WHEN: user mentions "logback", "spring boot logging", "java logging configuration", asks about "logback-spring.xml", "rolling file appender", "async logging in java" DO NOT USE FOR: SLF4J API usage - use `slf4j` instead, Log4j2 - use separate Log4j2 skill, Node.js logging - use `winston` or `pino` instead, Python logging - use `python-logging` instead
Project Lombok for reducing Java boilerplate. Covers annotations for getters, setters, constructors, builders, logging, and more. Based on production patterns from castellino and gestionale-presenze projects. USE WHEN: user mentions "lombok", "@Data", "@Builder", "@Slf4j", asks about "boilerplate reduction", "getters/setters", "@RequiredArgsConstructor", "@Value" DO NOT USE FOR: Java language features - use `java` skill instead DO NOT USE FOR: MapStruct integration - use `mapstruct` skill DO NOT USE FOR: Spring annotations - use `backend-spring-boot` skill
Critical Standard Bottom-Up Self-Check (check-standards, Convergence Gate) after Java backend code generation/modification. **This skill must be loaded after any Java code is written or modified—including scattered coding that does not follow the complete development process (e.g., "write an XX interface"/"write a Controller"/"help me write this code"): this skill must be loaded and verified before delivering code products to users**. It uses grep/ast-grep to actually scan and verify each standard—comments (class/field/method Javadoc/step comments, including private and extracted methods), logs (full class @Slf4j, each business method has logs, ERROR exceptions with stack traces), transaction rollbackFor, constructor injection, layered boundaries, SQL in XML, unified return body, pagination limit, password encryption, SQL comments/injection/WHERE, and all other verification items, with "File:Line Number" evidence attached to each item; **No level distinction—any item that is not implemented properly (regardless of importance) will be listed in the pending confirmation list to confirm with the user whether to complete it**. **Correct intermediate product naming and paths before verification** (Technical Solution 3.x.1 / Interface List 3.x.2 / Standard Verification Report 5.2.x / Acceptance Report 5.3.x, remove the task ID prefix T0xx from file names and move to the module version directory). Trigger scenarios: after writing code, after code generation, after modifying code, **before delivering code**, pre-submission check, code standard verification/review, comment and log verification, code review, standard self-check, bottom-up check, acceptance review, product file naming correction, file renaming and relocation, **perform standard scanning on specified directories/modules/packages (e.g., "run check-standards on xx directory"/"verify order module standards"/"only scan the code modified this time")**. It can be used with ai-dev-workflow 5.2 standard verification node / 5.3 acceptance, or triggered independently (output the report in the dialogue and prompt the user for confirmation when there are no docs/no process).
Lombok 注解使用规则技能。覆盖 @Data/@Builder/@Slf4j 组合规则、@EqualsAndHashCode(callSuper=true)继承陷阱、与Jackson/@Builder/@Jacksonized组合、与MyBatis无参构造器冲突解决、@Value不可变对象、@With对象复制、@SuperBuilder继承Builder。 纠正 LLM 最常见的 Lombok 误用：不写 callSuper、不加 @Jacksonized、Builder 与继承冲突、@Builder.Default 默认值丢失。
