  • field_types:
    • registry: text, email, password, number, boolean, date, datetime, phone, url, file, select, multiselect, hidden, rich_text, textarea
  • validation_expressions:
    • supported_rules: required, minLength, maxLength, min, max, pattern, email, url, custom

    • supported_operators: eq, neq, gt, gte, lt, lte, in, not_in, exists, not_exists
    • evaluation_order: top-to-bottom
    • max_conditions_per_field: 10
  • limits:
    • max_fields_per_form: 100
    • max_steps: 20
    • max_nested_groups: 3
  • versioning:
    • auto_increment: true
    • preserve_submissions: true

Outcomes

Form_created (Priority: 1)

Given:

  • user provides a form name
  • form name is unique within the account

Then:

  • create_record target: form — Create new form in draft status with version 1
  • emit_event event: form.created

Result: New form exists in draft status, ready for field configuration

Field_added (Priority: 2)

Given:

  • form is in draft status
  • field count is below 100
  • field type is in the supported registry

Then:

  • set_field target: form_fields — Append new field definition to form fields array
  • emit_event event: form.field_added

Result: Field appears in the form builder canvas at the specified position

Field_removed (Priority: 3)

Given:

  • form is in draft status
  • field exists in the form

Then:

  • set_field target: form_fields — Remove field and any conditions referencing it
  • emit_event event: form.field_removed

Result: Field removed from form, dependent conditions cleaned up

Conditional_visibility_applied (Priority: 4)

Given:

  • a condition is defined on a field
  • the referenced source field exists in the form
  • the operator is valid for the source field type

Then:

  • set_field target: form_fields — Update field visibility condition

Result: Field shows or hides dynamically based on the condition at render time

Form_published (Priority: 5) — Error: FORM_NOT_PUBLISHED

Given:

  • form is in draft status
  • form has at least one field
  • all field validations are properly configured
  • all conditional references point to existing fields

Then:

  • transition_state field: status from: draft to: published
  • set_field target: version — Increment version number
  • emit_event event: form.published

Result: Form is live and available for submissions

Form_submitted (Priority: 6)

Given:

  • form is in published status
  • all required fields have values
  • all field validations pass

Then:

  • create_record target: submission — Store submission data with reference to form version
  • emit_event event: form.submitted

Result: Submission recorded and confirmation shown to the user

Form_submission_invalid (Priority: 7) — Error: FORM_VALIDATION_FAILED

Given:

  • form is in published status
  • ANY: one or more required fields are empty OR one or more field validations fail

Then:

  • emit_event event: form.submission_failed

Result: Validation errors displayed inline next to the relevant fields

Max_fields_exceeded (Priority: 8) — Error: FORM_MAX_FIELDS_EXCEEDED

Given:

  • form_fields (computed) gte 100

Then:

  • emit_event event: form.limit_reached

Result: User informed that the maximum field limit has been reached

Errors

Code Status Message Retry
FORM_VALIDATION_FAILED 422 Please fix the highlighted errors before submitting Yes
FORM_MAX_FIELDS_EXCEEDED 400 Maximum of 100 fields per form has been reached No
FORM_NOT_FOUND 404 The requested form does not exist No
FORM_NOT_PUBLISHED 400 This form is not currently accepting submissions No
FORM_FIELD_TYPE_INVALID 400 The specified field type is not supported No

Events

Event Description Payload
form.created A new form was created in draft status form_id, name, created_by, timestamp
form.published A form was published and is now accepting submissions form_id, version, published_by, timestamp
form.submitted A form submission was received and stored form_id, submission_id, version, timestamp
form.field_added A field was added to a form form_id, field_name, field_type
form.field_removed A field was removed from a form form_id, field_name
form.submission_failed A form submission failed validation form_id, errors
form.limit_reached A form reached its maximum field count form_id, field_count
Feature Relationship Reason
drag-drop-editor recommended Drag-and-drop provides intuitive field placement in the form builder
wizard-stepper optional Multi-step forms use the wizard/stepper pattern for step navigation
accessibility recommended Form fields must meet WCAG 2.1 AA accessibility requirements
internationalization optional Form labels and validation messages may need translation

AGI Readiness

Goals

Reliable Form Builder

Dynamic form creation and rendering with drag-and-drop field placement, conditional visibility, multi-step forms, validation rules, and versioning

Success Metrics:

Metric Target Measurement
success_rate >= 99% Successful operations divided by total attempts
error_rate < 1% Failed operations divided by total attempts

Autonomy

Level: semi_autonomous

Escalation Triggers:

  • error_rate > 5

Tradeoffs

Prefer Over Reason
accessibility aesthetics UI must be usable by all users including those with disabilities
