Agent Tool Registry
Exposes named tools and their contracts to an agent for discovery and invocation
Why learn Agent Tool Registry?
It gives an agent a structured inventory of actions without embedding every implementation in the prompt.
The problem it solves
It connects model-selected capabilities to validated application functions and services.
Where it came from
A tool registry associates tool names with descriptions, input schemas, execution handlers, permissions, and error behavior. Large overlapping registries can reduce selection quality, so tools are often filtered for each task or role.
