+# GitHub Copilot Custom Instructions
+
+This repository is for the Multi-Agent Custom Automation Engine Solution Accelerator. Please follow these instructions to ensure Copilot suggestions align with our architecture, coding standards, and best practices.
+
+## General Guidelines
+- Use Python (3.10+) for backend code, and JavaScript (ES6+) for frontend code.
+- Backend: Prefer FastAPI for web APIs and asynchronous programming.
+- Frontend: Use vanilla JavaScript and Bulma CSS for UI. Avoid introducing new frameworks unless necessary.
+- Follow the existing folder structure: `src/backend` for backend, `src/frontend` for frontend, `infra/` for infrastructure-as-code (Bicep).
+- Use Azure services (Azure OpenAI, Azure Container Apps, Azure Cosmos DB, Azure Container Registry) for cloud components.
+- For infrastructure, prefer Bicep files in `infra/` over scripts. Use managed identity for authentication, never hardcode credentials.
+- Always include error handling, logging, and comments for key logic.
+- Use English for all code, comments, and documentation.
+
+## Security & Compliance
+- Store secrets in Azure Key Vault, not in code or config files.
+- Follow the Microsoft Open Source Code of Conduct and security guidelines.
+- Do not use or suggest deprecated Azure services or insecure patterns.
+- Reference [OpenAI Usage Policies](https://openai.com/policies/usage-policies/) and [Azure OpenAI Code of Conduct](https://learn.microsoft.com/en-us/legal/cognitive-services/openai/code-of-conduct) for responsible AI use.
+
+## Coding Style
+- Use clear, descriptive variable and function names.
+- Write modular, reusable code with separation of concerns.
+- Use async/await for asynchronous operations in both Python and JavaScript.
+- Prefer parameterized queries and proper indexing for database access.
+- Add docstrings (Python) and JSDoc (JavaScript) for public functions.
+- Use consistent indentation (4 spaces for Python, 2 spaces for JS/HTML/CSS).
+
+## Pull Requests & Contributions
+- Ensure all new code includes tests where applicable.
+- Follow the repository's contribution guidelines in `CONTRIBUTING.md`.
+- Reference the `README.md` and `docs/` for architecture and usage patterns.
+
+## Azure Best Practices
+- Use managed identity for Azure SDK authentication.
+- Never hardcode credentials; use Key Vault.
+- Validate deployments with `azd provision --preview` or `az deployment group what-if` before running them.
+- Prefer `azd` for deployments; use Bicep for IaC.
+- Enable logging, monitoring, and error handling for all Azure resources.
+
+## Responsible AI
+- Default to GPT-4o for LLM tasks unless otherwise specified.
+- Enable caching for reliability and cost control.
+- Do not use the system for medical or financial advice.
+

+For more details, see the `README.md`, `docs/`, and `documentation/` folders.
