ageri-sdk

Create a mini-application named 'PersonalAIAssistant' using the Python package 'ageri-sdk'. This application will serve as a personal AI assistant that can perform various tasks based on user commands. It will utilize the core features of the 'ageri-sdk' such as Skill contracts, SkillResult, Task, OrchestratorContext, and proxy ABCs to manage and execute tasks efficiently.

Step-by-Step Instructions:
1. Initialize the project with a virtual environment and install the 'ageri-sdk' package.
2. Define skill contracts for different functionalities like 'weather', 'news', 'calendar', etc., each implementing the SkillBase interface provided by 'ageri-sdk'.
3. Implement the SkillResult class to handle the output of these skills, ensuring it can process and present data from each skill effectively.
4. Use the Task class to queue and manage requests for these skills, allowing the application to handle multiple requests concurrently.
5. Create an OrchestratorContext to coordinate between the skills and the tasks, ensuring seamless interaction and task execution.
6. Develop proxy classes that act as intermediaries between the user and the skill implementations, enhancing the flexibility and scalability of the application.
7. Integrate a simple user interface (CLI or basic web interface) that allows users to input commands and receive results from their PersonalAIAssistant.
8. Test the application thoroughly to ensure all skills work as expected and can handle various inputs gracefully.
9. Document the code and provide instructions on how to run the application.

Suggested Features:
- Ability to add new skills easily by extending the SkillBase interface.
- Support for both synchronous and asynchronous task execution.
- Logging mechanism to track the execution of tasks and skills.
- Error handling to manage unexpected situations gracefully.
- User authentication and authorization to secure access to the personal assistant.
