Good defaults smart prefills

forms.inputs.good_defaults_smart_prefills

Prefill with good defaults and smart values the user can accept or edit.

Description

Prefill with good defaults and smart values the user can accept or edit. Pass when known defaults, history, or frequent values appear prefilled and remain editable; fail when the user must retype a known default, history, or frequent value with no prefill. Defaults should speed completion, not lock the user into an uneditable guess they cannot change.

When to use

Fields with known defaults, history, or frequent prior values.

Not when

First-time fields with no reliable default or history to offer.

Agent hint

Prefill known defaults or frequent values and keep them editable.

Pass

Known defaults, history, or frequent values are prefilled and editable.

Fail

User retypes a known default/history/frequent value with no prefill.
