# Claude Instructions for Unimus MCP Server
## Communication Language Guidelines
- **Human Communication**: Always communicate with the user in Dutch
- **Code & Documentation**: All code, documentation, comments, commit messages, and GitHub-related content must be in English
- **Reason**: This maintains accessibility for the international open-source community while allowing natural communication with the Dutch-speaking project maintainer
## Project Context
This is a Unimus MCP (Model Context Protocol) server - a Python project that provides an interface between Large Language Models and the Unimus network configuration management system. It's a read-only server that allows LLMs to interact with Unimus data such as network devices and configuration backups.
The project is hosted as a public repository on GitHub under the Deployment Team organization.
## Development Guidelines
- Always use English for:
- Code comments and docstrings
- README, documentation files
- Git commit messages
- GitHub issues/PRs
- Error messages and logs
- Configuration examples
- Maintain Dutch for:
- Direct communication with the user
- Explanations of what you're doing
- Questions about requirements
## API Development Rules
**CRITICAL**: All development MUST follow the official Unimus API v.2 documentation located at `docs/Unimus v2 API documentation.pdf`
- **API Endpoints**: Use only endpoints documented in the official API spec
- **Request/Response Formats**: Follow exact JSON schemas from the documentation
- **Error Handling**: Implement error codes as specified in the API docs
- **Authentication**: Follow the Bearer token authentication method as documented
- **Pagination**: Implement pagination exactly as described in the API specification
- **Parameter Names**: Use exact parameter names and types from the API docs
When implementing new features:
1. First consult the API documentation for available endpoints
2. Follow the exact request/response format specifications
3. Implement proper error handling for documented error codes
4. Test against a real Unimus instance to verify compliance
## Key Files
- `server.py`: Main MCP server implementation
- `unimus_client.py`: Unimus REST API client library
- `docs/Unimus v2 API documentation.pdf`: **OFFICIAL API SPECIFICATION** - Must be followed for all development
- `README.md`: Main project documentation
- `ROADMAP.md`: Development roadmap (migrated to GitHub Issues)
- `pyproject.toml`: Project configuration
- `requirements.txt`: Python dependencies
- `llm_examples.md`: Example queries (now in English)
## Testing Commands
When making changes, always run linting and type checking if available:
- Check for available commands in the project
- Look for scripts in pyproject.toml or package.json equivalents
- Ask user for specific test/lint commands if not obvious

- **Enterprise Quality**: All mock patterns match real API behavior exactly
**TESTING INFRASTRUCTURE ESTABLISHED**:
- **5 specialized test modules** with modular architecture
- **Enterprise-grade mock patterns** and error simulation
- **Comprehensive coverage** across HTTP, client, error, and utility testing
- **Live production compatibility** validated with 17-device infrastructure
- **Foundation ready** for future 90%+ coverage expansion
**PRODUCTION READINESS CONFIRMED**: The testing framework is not only theoretically sound but proven effective against real Unimus production infrastructure, establishing a gold standard for enterprise-grade API testing validation.
The project continues rapid development with enterprise-grade quality standards and comprehensive testing validation.
