Clarify First

Before optimizing the form, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Form type — lead capture, contact, demo, application, or checkout (sets the optimal field count and playbook)
• Current fields + which are used in follow-up — reveals which fields to cut or enrich (the core of field-cost analysis)
• Current completion rate + where users abandon — baseline and the specific friction point to target
• Compliance requirements — GDPR/HIPAA fields that cannot be removed (constrains the field reduction)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the audit.
