COMPEL Glossary / tool-registry

Tool registry

An authoritative inventory of tools — with schemas, permissions, owners, deprecation state, and audit log — that an agent may call.

What this means in practice

The tool registry is the governance anchor for agentic systems: unregistered tools cannot be invoked; permission changes flow through the registry rather than through prompt updates.

Synonyms

agent tool registry , tool inventory
