What are LLM Tools?

LLM tools run structured extraction against the current step’s conversation. The assistant reads what the caller has said and returns clean, typed data you can store in variables and route on. There are two LLM tools:

Tool	Use when you need
LLM Data	One typed value — a name, email, number, date, appointment time, reference number, or category
LLM Custom	Several flat fields from the same answer, extracted in one call

When extraction passes

All LLM extraction only passes when the caller is directly answering the assistant’s current-step question, or affirming the assistant’s immediately preceding confirmation question. Counter-questions, subject changes, deflections, unrelated answers, and vague answers return false.

Output

Both tools expose a single result boolean.

Value	Meaning
`true`	A valid value was extracted, and any configured writes succeeded
`false`	Required inputs were missing, schema validation failed, no conversation was available, or extraction failed

Use the result boolean for tool-step conditions, and a destination/response map to store the extracted values.

Choosing between them

Need just one field? Use LLM Data — it offers typed extraction modes (text, number, date, date & time, enum).
Need a small group of related fields, like contact or claim details? Use LLM Custom with a flat schema.
