Tool Definition And Invocation Routing

via “tool invocation routing and execution”

Library for building agents, using tools, planning

Unique: Implements a simple name-based tool routing mechanism that matches Action strings to ToolInterface instances, avoiding the complexity of LangChain's tool registry or function calling schemas. The routing is explicit and transparent, allowing developers to see exactly how tools are selected and invoked.

vs others: Simpler than LangChain's tool routing because it uses direct name matching instead of semantic similarity or schema validation, but less robust because it doesn't validate that tools exist or handle missing tools gracefully.
