Usage Examples

Create a form

"Create a bug report form with title, severity, and description"
→ create_form(name="Bug Report", fields=[
    {label:"Title", field_type:"text", required:true},
    {label:"Severity", field_type:"select", options:["Low","Medium","High","Critical"]},
    {label:"Description", field_type:"textarea"}
  ])

Submit with validation

"Submit feedback: name=Carol, email=carol@test.com, rating=4"
→ submit_form(form_id="form-feedback", data={"Name":"Carol","Email":"carol@test.com","Rating":4})
→ "Submission sub-xxx accepted"

Validation errors

→ submit_form(form_id="form-feedback", data={"Name":"","Email":"bad","Rating":7})
→ "Submission has validation errors: ['Name' is required, 'Email' must be valid, 'Rating' must be 1-5]"

Analytics

"What's the average rating on the feedback form?"
→ get_analytics(form_id="form-feedback")
→ {"Rating": {"average": 4.0, "count": 3}, "total_submissions": 45}

Validation Pipeline

Input → Required check → Type check → Format validation → Options check → ✅ Accept / ❌ Reject with errors
