A developer encountered challenges integrating different LLM providers for a tool-calling loop in a healthcare application. Initially, the loop worked seamlessly with OpenAI's SDK, but compliance requirements necessitated a second model from a different provider, Anthropic, to cross-check the results. The developer discovered that Anthropic's API for tool use had a different structure than OpenAI's, requiring a significant rewrite of the loop. However, the `@aviasole/shapecraft` library simplified this by providing a unified interface, allowing the same tool-calling logic to be applied to both OpenAI's GPT-4o mini and Anthropic's Claude Haiku 4.5, resolving the integration issue with minimal code changes.
