Enforces strict search scopes and guides the user through testing and build system configurations.\n---\n# Android Studio Development Skill\nYou are an expert in Android Studio plugin development. You must follow these operational rules and read the specific reference files when the context demands it.\n\n## 1. Code Search Constraints (Strict)\n**You must adhere to these search limitations to ensure performance and relevance:**\n* **Subdirectories Only:** NEVER search at the root of the project (`studio-main`). It is too large.\n* **Targeted Sequence:** Always search within smaller, specific directories in sequence:\n  * Good candidates: e.g. `tools\u002Fvendor\u002Fgoogle`, `tools\u002Fadt\u002Fidea`.\n  * Use the context of the user's request to determine relevant submodules.\n\n## 2. Module Management\n**New Modules:** If you create a new `.iml` module file, you must strictly remind the user to update the `modules.xml` file so IntelliJ IDEA recognizes the new module.\n\n## 3. Testing Guidelines\n**When the user asks about writing, debugging, or running tests:**\n* **Action:** You MUST read the file `writing-tests.md` located in this skill directory.\n* **Summary:** That file contains critical instructions on:\n  * Using JUnit 4 and Google Truth (preferred assertions).\n  * The distinction between Pure Unit Tests, IntelliJ Platform \"Light\" Tests, and Integration Tests.\n  * The preference for handwritten Fakes over Mockito.\n\n## 4. Build System (Bazel & JPS)\n**When the user asks about builds, dependencies, or configuration:**\n* **Action:** You MUST read the file `build-system.md` located in this skill directory.\n* **Summary:** `build-system.md` contains critical instructions on:\n  * The hybrid JPS (`.iml`) and Bazel (`BUILD.bazel`) workflow.\n  * When you should edit `.iml` files (the usual case) vs when you should edit `BUILD`\u002F`BUILD.bazel` files.\n  * Running tests via `bazel test` with correct target naming and filtering.\n",{"data":34,"body":35},{"name":4,"description":6},{"type":36,"children":37},"root",[38,47,53,60,69,132,138,164,170,178,227,233,241],{"type":39,"tag":40,"props":41,"children":43},"element","h1",{"id":42},"android-studio-development-skill",[44],{"type":45,"value":46},"text","Android Studio Development Skill",{"type":39,"tag":48,"props":49,"children":50},"p",{},[51],{"type":45,"value":52},"You are an expert in Android Studio plugin development.
