Change a live lead form

Say this first, because it surprises everyone

Meta lead forms cannot be edited. Not by this tool, not in Ads Manager, not at all. Once a form is published it is frozen. So "add a question" means: create a new form, create a new creative pointing at it, and point the ad at that creative. One change, three steps, no way around it.

The old form is never deleted. It keeps the leads it already collected, which is why deleting it would be the wrong move even if you could.

Edit the form

In campaign.json, under lead_form. Two rules Meta enforces and will reject the form over:

• The consent checkbox must default to unchecked. A pre-checked box is rejected.
• Bullets in a list-style greeting must be under 80 characters each.

Run it

PYTHONPATH="${CLAUDE_PLUGIN_ROOT}" python3 -m adscooking form

Dry run first. Then, only if they confirm:

PYTHONPATH="${CLAUDE_PLUGIN_ROOT}" python3 -m adscooking form --go

Afterwards, do not skip this

It prints a new form_id. Update live.form_id in campaign.json to that value. If you do not, the next copy change will point the ad back at the old form and quietly undo this.

Then tell them to check where the leads go. If leads flow into an email tool or CRM, that connection is usually tied to the form, not the ad. A new form often means the connection has to be repointed, and the failure mode is silent: the ads keep running, the leads keep coming, and nothing arrives in the tool that is supposed to receive them. Worth a test lead.

Fewer questions get more leads

If they are adding questions, it is fair to mention the tradeoff once: each extra field costs completions. Say it once, then do what they asked.
