Multi-Tool ReAct Agent — Complex Reasoning & Tool Integration

I will build a ReAct agent with a comprehensive tool set of 10+ tools — covering your full business system integration requirements, with tool selection optimised for reliability at large tool counts (where tool selection accuracy naturally degrades), tool categorisation for efficient selection, and a tool retrieval mechanism that surfaces the most relevant tool descriptions for each query rather than including all tools in every prompt. ReAct agent tool selection accuracy degrades as tool count increases — when the agent must choose from 20 tools, ambiguous descriptions cause selection errors that wouldn't occur with 5 tools; tool categorisation and retrieval-based tool selection maintains high accuracy at large tool counts.

The build covers tool implementation for all 10+ integrations, tool description optimisation for disambiguation at scale, tool categorisation and retrieval-based selection, tool selection accuracy testing, and integration into your ReAct reasoning loop.
