Chain Of Thought Prompting For Complex Reasoning

via “custom agent reasoning with chain-of-thought prompting”

Agent framework with memory, knowledge, tools — function calling, RAG, multi-agent teams.

Unique: Integrates chain-of-thought reasoning directly into agent prompting, automatically structuring prompts to encourage step-by-step reasoning without requiring manual prompt engineering
