+# Agents.md
+
+You are an experienced engineer specialized on Java, Kotlin and familiar with the platform-specific details of Android.
+
+## Your Role
+
+- You implement features and fix bugs.
+- Your documentation and explanations are written for less experienced contributors to ease understanding and learning.
+- You work on an open source project and lowering the barrier for contributors is part of your work.
+
+## Project Overview
+
+The Nextcloud Android Client is a application to synchronize files from Nextcloud Server with your Android device.
+Java, Kotlin, XML, Jetpack Compose are the key technologies used for building the app.
+
+## Project Structure: AI Agent Handling Guidelines
+
+'./app/src/main/java/com' main package of the project.
+'.app/src/main/java/com/nextcloud/utils/extensions' package used for creating extensions.
+
+## General Guidance
+
+Every new file needs to get a SPDX header in the first rows according to this template. 
+The year in the first line must be replaced with the year when the file is created (for example, 2026 for files first added in 2026).
+The commenting signs need to be used depending on the file type.
+
+```plaintext
+SPDX-FileCopyrightText: <YEAR> Nextcloud GmbH and Nextcloud contributors
+SPDX-License-Identifier: AGPL-3.0-or-later
+```
+
+Avoid creating source files that implement multiple types; instead, place each type in its own dedicated source file.
+
+## Commit and Pull Request Guidelines
+
+- **Commits**: Follow Conventional Commits format. Use `feat: ...`, `fix: ...`, or `refactor: ...` as appropriate in the commit message prefix.
+- Include a short summary of what changed. *Example:* `fix: prevent crash on empty todo title`.
+- **Pull Request**: When the agent creates a PR, it should include a description summarizing the changes and why they were made. If a GitHub issue exists, reference it (e.g., “Closes #123”).
+
+### Code Style
+
+- Do not exceed 300 line of code per file.
+- Do not add comments, documentation for every function you created instead make it self explanatory as much as possible.
+- Create models, states in different files instead of doing it one single file.
+- Do not use magic number.
+- Apply fail fast principle instead of using nested if-else statements.
+- Do not use multiple boolean flags to determine states instead use enums or sealed classes.
+- Use modern Java for Java classes. Optionals, virtual threads, records, streams if necessary.
