Create an `AGENT.md` file anywhere in your project's file system. Gemini\n scans the current directory and all parent directories for `AGENT.md` files when\n you submit a query. For more details, see [How `AGENT.md` files work](#how-agent-files-work).\n\n | **Tip:** Use multiple instruction files across different directories for more granular control over different parts of your codebase. For example, you can have a global `AGENT.md` file at the project root and more specific `AGENT.md` files in subdirectories for different modules.\n2. Add your instructions. Write your instructions using Markdown. For\n readability, consider using headings and bullet points for different rules.\n [See example instructions](#example-instructions).\n\n3. Save and commit the file to your VCS to share it with your team.\n\nManage `AGENT.md` files as context\n----------------------------------\n\nYou can apply or remove `AGENT.md` files as context for a particular query\nusing the **Context** drawer in the chat panel. The **`AGENT.md` Files** options\nincludes all `AGENT.md` files in the current directory and its parent\ndirectories.\n**Figure 1.** Manage `AGENT.md` files as context.\n\nExample instructions\n--------------------\n\nYou can use the `AGENT.md` file to give instructions to the agent. The following\nare some examples, but the instructions that you provide should be specific to\nyour project.\n\n- \"The main activity is `/path/to/MainActivity.kt`.\"\n- \"The code to support navigating between screens is `path/to/navigation/UiNavigation.kt`\"\n- \"The code handling HTTP requests is at `\u003cpath\u003e`.\"\n- Project architecture\n - \"Place all business logic in ViewModels.\"\n - \"Always follow official architecture recommendations, including use of a layered architecture. Use a unidirectional data flow (UDF), ViewModels, lifecycle-aware UI state collection, and other recommendations.\"\n- Preferred libraries: \"Use the \\\u003clibrary name\\\u003e library for navigation.\"\n- Defining placeholder names for common API services or internal terminology: \"The primary backend service is referred to as 'PhotoSift-API'.\"\n- Company style guides: \"All new UI components must be built with Jetpack Compose. Don't suggest XML-based layouts.\"\n\nModularize your `AGENT.md` files\n--------------------------------\n\nYou can break down large `AGENT.md` files into smaller files that can be reused\nin different contexts:\n\n1. Separate out a set of instructions and save them in another Markdown file,\n such as `style-guidance.md`.\n\n2. Reference the smaller Markdown files in an `AGENT.md` file by using the `@`\n symbol followed by the path to the file you want to import. The following path\n formats are supported:\n\n - Relative paths:\n - `@./file.md` - Import from the same directory\n - `@../file.md` - Import from the parent directory\n - `@./subdirectory/file.md` - Import from a subdirectory\n - Absolute paths: `@/absolute/path/to/file.md`\n\nFor example, the following `AGENT.md` file references two other instruction\nfiles: \n\n # My AGENT.md\n\n You are an experienced Android app developer.\n\n @./get-started.md\n\n ## Coding style\n\n @./shared/style-guidance.md\n\nHow `AGENT.md` files work\n-------------------------\n\nGemini automatically scans the current directory and parent directories for\n`AGENT.md` files and adds their content to the beginning of every prompt as a\npreamble. If you don't have a file open when you submit a query, then the\n`AGENT.md` file at the project root (if there is one) is included by default.\n| **Note:** If you have a `GEMINI.md` file and `AGENT.md` file in the same directory, the `GEMINI.md` file takes precedence.\n\nWhat's the difference between `AGENT.md` files and Rules?\n---------------------------------------------------------\n\n[Rules](/studio/gemini/rules) also let you define instructions and preferences\nthat apply to all prompts. However, rules are defined in the IntelliJ file\n`/.idea/project.prompts.xml`, whereas `AGENT.md` files are saved next to your\nsource code and are IDE-neutral. We recommend using `AGENT.md` files if one of\nthe primary purposes is to share the instructions with your team.\n| **Note:** Gemini combines rules and instructions in `AGENT.md` files when processing your query."]]
