The blog post outlines the development of a note-saving tool using Pydantic for validation and the Claude API from Anthropic. Key steps include setting up the environment with necessary libraries, defining Pydantic models for notes and authors, and implementing a tool to save notes with metadata. The defined models ensure input and response validation, enhancing reliability during interaction. A simple saving function is included, which prints a success message upon execution. The post provides an example of chatbot interaction, showcasing how user input can be processed to save a note through the tool. Ultimately, this implementation demonstrates the effective use of schema validation to maintain the integrity of data handled by the chatbot.

The blog post outlines a procedure for utilizing Vision with a custom tool to extract structured nutrition information from an image of a nutrition label. It begins with the installation of libraries and setup of the Claude API client. A custom tool named “print_nutrition_info” is defined, capable of extracting details such as calories, total fat, cholesterol, total carbohydrates, and protein from the image. The post details the process of encoding the nutrition label image, submitting it along with a prompt, and invoking the tool to retrieve neatly formatted JSON data with the nutrition information. The response from the Claude API is analyzed to ensure the tool was successfully called, with provisions for handling situations where it was not. This illustrates the blend of AI and image processing to facilitate nutrition label analysis.
