Astro Forms Skill

Form infrastructure. Backend only. UI is separate.

Purpose

Server-side form handling. Validation, email, storage, spam protection.

Output

form_ready: true
data_contract: [lead_id, source_page, timestamp, gdpr_consent]
post_submit_flow: [email, thank_you, analytics]
conversion_verdict: PASS | WARN | FAIL

Primary Conversion Declaration

One form per page is THE conversion.

primary_conversion:
  type: form
  id: "contact-form"
  page: "/contact"

All other forms are secondary (newsletter, etc.).

Page Exclusion Rules

Page Type	Forms Allowed
landing	✅ Primary only
service	✅ Primary only
calculator	❌ Use calculator skill
thank-you	❌ Forbidden
404	❌ Forbidden

Form on forbidden page = FAIL.

Data Integrity Contract

Every submission MUST contain:

data_contract:
  required:
    - lead_id          # Unique, generated
    - source_page      # URL where submitted
    - timestamp        # ISO datetime
    - gdpr_consent     # true + timestamp
    - ip_hash          # Anonymized
  optional:
    - utm_source
    - utm_medium
    - utm_campaign

Missing required field = submission invalid.

post_submit_flow:
  1_confirmation_email: required
  2_thank_you_redirect: required
  3_analytics_event: required

Step	What	FAIL if
