# Edit an item
> Change what one item extracts, or how.
```json theme={"dark"}
{ "name": "Lead Temperature",
"description": "How ready the caller is to buy, judged from what they actually said — not tone.",
"result_format": "string",
"constraints": { "enum": ["hot", "warm", "cold"] } }
```
**`description` is the instruction the model reads, not a label.** Editing it is how you fix bad
extractions — tighten the direction rather than renaming the field.
Changing `result_format` or `constraints` changes the shape of the value on every future call. Past
calls keep whatever they were analysed with, so a consumer reading a warehouse column across a
format change will see both shapes — narrow an `enum` and older rows may hold values no longer in
the list.
**Built-in values are only partly editable.** On an item Vocily ships, you may change
`description` and `enabled`. `name`, `result_format` and `constraints` are refused
with `409`: the name is the key on the call payload, and the sentiment filter's enum is built
from the format and constraints, so readers elsewhere assume them. The description — what the
model is actually told — is the part worth tuning, and is why these live here at all.
Renaming an item has the same consequence as renaming a group: the name is part of the key on the
call payload, `custom_analysis["Lead QA"]["Lead Temperature"]`.

description: >-
Public REST API for Vocily. Build and configure an agent, publish a version
and put it live, place outbound calls, and read back calls, chats and what
the agent remembered. Authenticate with a workspace API key as a Bearer
token.
Some things stay in the dashboard, by design: creating an API key, buying or
connecting a phone number, setting an agent's webhook URL, connecting
WhatsApp and its templates, building HTTP tools, and running batch
campaigns.
