hi @Mahesh_Gunaje,
AFAIK, there is no out-of-the-box tool designed to automatically generate implementation guides or authoring guides from Content Fragment Model XML files in AEM. I see two possible approaches here: manual and programmatic.
You could create standardized documentation templates that include:
For Implementation Guides:
Model path and configuration location
Data type definitions for each field
Property names and validation rules
GraphQL query examples
Fragment reference relationships
For Authoring Guides:
Field labels and descriptions
Required vs. optional fields
Character limits and validation requirements
Visual examples of completed fragments
Usage guidelines for variations
Alternatively, you could develop a custom documentation generator. This would involve creating a Java or Node.js script that reads CFM XML files from /conf/<project>/settings/dam/cfm/models/, parses the structure, and outputs documentation in your desired format.
