+# GitHub Copilot Instructions for Agent365-python
+
+## Code Review Rules
+
+### Rule 1: Check for "Kairo" Keyword
+- **Description**: Scan code for any occurrence of the keyword "Kairo"
+- **Action**: If "Kairo" is found in any code file:
+  - Flag it for review
+  - Suggest removal or replacement with appropriate terminology
+  - Check if it's a legacy reference that needs to be updated
+- **Files to check**: All `.py` files in the repository
+
+### Rule 2: Verify Copyright Headers
+- **Description**: Ensure all Python files have proper Microsoft copyright headers
+- **Action**: If a `.py` file is missing a copyright header:
+  - Add the Microsoft copyright header at the top of the file
+  - The header should be placed before any imports or code
+  - Maintain proper formatting and spacing
+
+#### Required Copyright Header Format
+```python
+# Copyright (c) Microsoft Corporation.
+# Licensed under the MIT License.
+```
+
+### Implementation Guidelines
+
+#### When Reviewing Code:
+1. **Kairo Check**:
+   - Search for case-insensitive matches of "Kairo"
+   - Review context to determine if it's:
+     - A variable name
+     - A comment reference
+     - An import statement
+     - A string literal
+   - Suggest appropriate alternatives based on the context
+
+2. **Header Check**:
+   - Verify the first non-empty, non-shebang lines of Python files
+   - If missing, prepend the copyright header
+   - Ensure there's a blank line after the header before other content
+   - Do not add headers to:
+     - `__init__.py` files that are intentionally empty
+     - Generated files (if marked as such)
+
+#### Example of Proper File Structure:
+```python
+# Copyright (c) Microsoft Corporation.
+# Licensed under the MIT License.
+
+"""Module docstring goes here."""
+
+import os
+import sys
+
+# Rest of the code...
+```
+
+### Auto-fix Behavior
+When Copilot detects violations:
+- **Kairo keyword**: Suggest inline replacement or flag for manual review
+- **Missing header**: Automatically suggest adding the copyright header
+
+### Exclusions
+- Test files in `tests/` directory may have relaxed header requirements (but headers are still recommended)
+- Third-party code or vendored dependencies should not be modified
+- Configuration files (`.toml`, `.json`, `.yaml`, `.md`) do not require Python copyright headers
