+## Branch & PR Guidelines
+
+### Overview
+This repository uses a branch-based development workflow. Please follow the conventions below when working in this project, especially when creating branches, writing PR titles, and generating commits or documentation.
+
+### Branch Naming
+Use the following prefixes:
+- `feature/<name>` for new features
+- `fix/<name>` for bug fixes
+- `refactor/<name>` for refactorings
+- `docs/<name>` for refactorings
+- `test/<name>` for tests
+
+Avoid slashes other than the prefix.
+
+### PR Titles
+Format:
+`[<type>] <Short summary>`
+
+Allowed types: `feature`, `fix`, `refactor`, `docs`, `test`
+
+Examples:
+- `[feature] Add user registration`
+- `[bugfix] Fix memory leak in sync module`
+
+### Notes for Agents
+- Never propose changes directly on `master`.
+- Always create a branch using the proper prefix.
+- PR titles must follow the documented format.
