appium-skill
Generates production-grade Appium mobile automation scripts for Android and iOS in Java, Python, or JavaScript. Supports real device and emulator testing locally and on TestMu AI cloud with 100+ real devices. Use when the user asks to automate mobile apps, test on Android/iOS, write Appium tests, or mentions "Appium", "mobile testing", "real device", "app automation". Triggers on: "Appium", "mobile test", "Android test", "iOS test", "real device", "app automation", "UiAutomator", "XCUITest driver", "TestMu", "LambdaTest".
java-lsp-tools
Compiler-accurate Java code intelligence tools powered by the Java Language Server. ALWAYS load this skill when the workspace contains Java, Maven (pom.xml), or Gradle (build.gradle) projects. Use these tools to find symbol definitions, get type/call hierarchies, resolve types, inspect file outlines, and check imports in Java source files. Prefer over grep_search or read_file for any Java code navigation, understanding, debugging, or refactoring task.
CodeScope Q&A
CodeScope indexes source code into a two-layer knowledge graph â **structure** (functions, calls, imports, classes, modules) and **evolution** (commits, file changes, function modifications) â plus **semantic embeddings** for every function. Supports **Python, JavaScript/TypeScript, C, and Java*
coderlm
Primary tool for all code navigation and reading in supported languages (Rust, Python, TypeScript, JavaScript, Go, Java, Scala, SQL). Use instead of Read, Grep, and Glob for finding symbols, reading function implementations, tracing callers, discovering tests, and understanding execution paths. Provides tree-sitter-backed indexing that returns exact source code â full function bodies, call sites with line numbers, test locations â without loading entire files into context. Use for: finding functions by name or pattern, reading specific implementations, answering 'what calls X', 'where does this error come from', 'how does X work', tracing from entrypoint to outcome, and any codebase exploration. Use Read only for config files, markdown, and unsupported languages.
fastexcel-to-fesod
Migrates a Java project from FastExcel 1.3 (cn.idev.excel:fastexcel:1.3.0) to Apache Fesod (org.apache.fesod:fesod-sheet:2.0.1-incubating). Invoke this skill when asked to "migrate FastExcel to Fesod", "upgrade to Apache Fesod", or "replace cn.idev.excel". FastExcel 1.3 is the direct predecessor of Apache Fesod. Supports both legacy namespaces seen in real projects: cn.idev.excel.* and org.apache.fesod.excel.*. The entry classes FastExcel and FastExcelFactory are kept as @Deprecated aliases in Fesod, so call-site renames are strongly recommended but NOT required for compilation. The only breaking change is the Java package prefix.
dedup-openai
Suppress generated Java classes that duplicate openai-java models, using @@alternateType in TypeSpec and manual serialization bridges. Use after dup-classes has identified actionable duplicates.

dr-jskill
Creates Java + Spring Boot projects: Web applications, full-stack apps with Vue.js or Angular or React or vanilla JS, PostgreSQL, REST APIs, and Docker. Use when creating Spring Boot projects, setting up Java microservices, or building enterprise applications with the Spring Framework.
asdf
Use this skill whenever the user wants to install, configure, or use asdf (asdf-vm), the universal version manager. Trigger for any mention of asdf, .tool-versions files, managing runtime versions, switching between versions of Node.js, Python, Ruby, Go, Terraform, kubectl, Java, Erlang, Elixir, or any other tool managed by asdf. Also trigger when migrating from nvm, pyenv, rbenv, goenv, tfenv, or similar single-language version managers. Use this skill for help with asdf plugins, asdf install, asdf set/global/local, troubleshooting shims, Fish/Bash/Zsh shell configuration, and multi-project version isolation workflows.
