DN FIELD GUIDE · INITIAL RELEASE
Tool calling
A model emits a structured request for an external function; the application validates and executes it.

See it in a workflow
The model requests a price lookup, which the application sends to a market-data API.
The failure mode
A model request is not itself user consent to execute a transaction.
Illustrative scenario, not a measured execution test.

Primary documentation
Evidence before authority
DN’s reference hub connects concepts, official sources and practical review questions. It is an editorial reference, not a security certification or legal advice. Entries are dated snapshots, not a continuously monitored feed. Coverage expands only after review.
Commercial relationships do not determine definitions, regulatory conclusions or default tool order. Follow provider eligibility rules and verify permissions before execution.
