logic, and fallback strategies in multi-agent systems
Integrate with foundation model APIs (AWS Bedrock, OpenAI, or equivalent) for LLM-powered reasoning,
decision-making, and natural language understanding within agent pipelines
Build tool-use and function-calling interfaces that allow AI agents to interact with databases, APIs,
