Building a Minimal Tooling Layer: Tool Registry, Router, and Tracing
Why you need a tooling layer
Without structure, tools become scattered functions. A tooling layer provides registration, validation, routing, and observability.
Tool registry
A registry holds: name, schema, handler, permissions, timeouts. The agent only sees the names and descriptions.
Router
The router dispatches calls, validates inputs, injects identity (user/tenant), and enforces policies.
Tracing
Trace IDs should flow across LLM calls and tool calls. This is how you debug multi-step runs.
