Canvas AI: Updating page contents with agents

Overview

Currently, the "Canvas Page Builder" agent can only add new components to the page. It should also be able to:

Update the content of components (Eg:. when a user selects a component and asks to summarize or rewrite its content).
Rearrange components (Eg: when a user selects a component and asks to move it to a different region, slot, or position).

Proposed resolution

• Store the component data containing UUID and prop values in the tempstore.
• Create a tool named 'get_component_content' that accepts the UUID (string, required) of a component and returns its prop values.
• Create a validator to validate that the UUID provided exists in the page.
• Create a new tool named 'update_component_data' that accepts a UUID (string, required) and prop (list, required). Within this tool, validate the following:
  • The provided UUID is valid.
  • The prop names and values are valid.
• Create a new tool named 'move_component_in_page' that accepts the following:
  • Component UUID (string, required)
  • Region (string, optional)
  • Reference UUID (string, optional)
  • Placement (string, with allowed values 'above' or 'below')
• Within this tool, validate the following:
  • UUID is valid.
  • Region is used only when there are no child components in that region (used to move a component to an empty region). If region is used, reference UUID must not be provided.
  • If reference UUID is provided, then placement must be provided.
• Update the set_component_structure tool to return a UUID for all the newly added components.
• Store the output of CanvasAiPageBuilderHelper::createExpectedPageLayout in tempstore so that it can be accessed in the 'update_component_data' and 'move_component_in_page' tools, for handling cases with component addition, update, and move in a single go.
