data360-schema-get Skill
Overview
This skill retrieves Data Lake Object (DLO) and Data Model Object (DMO) schema information from Salesforce Data Cloud using the SSOT REST API. It can list all DLOs or DMOs in an org, or retrieve detailed schema for a specific DLO or DMO.
When to Use
- User wants to see all DLOs or DMOs in a Data Cloud org
- User needs field schema for a specific DLO or DMO
- User is exploring Data Cloud data structures
- User needs to understand DLO or DMO field types and metadata
Prerequisites
- SF CLI installed and authenticated to target org
- Org has Data Cloud enabled
- User has appropriate Data Cloud permissions
Skill Execution
Parameters
- org_alias (required): The SF CLI org alias (e.g., 'afvibe', 'myorg')
- dlo_name (optional): Specific DLO developer name (e.g., 'Employee__dll')
- dmo_name (optional): Specific DMO developer name (e.g., 'Individual__dlm')
Step 1: Discover Connected Org
First, run sf org list to find out which org is connected and extract the alias to use for all subsequent calls:
Example output:
Extract the Alias value (e.g., myorg) from the output and use it as the <org_alias> for all subsequent calls. Use --all to see expired and deleted scratch orgs as well.
Step 2: Validate SF CLI Authentication
Before making API calls, verify the org is connected:
If not connected, inform user to run:
Step 3a: Execute DLO Schema Script
The Python scripts are bundled with this skill in the scripts/ subdirectory.
To list all DLOs:
To get specific DLO schema:
Step 3b: Execute DMO Schema Script
To list all DMOs:
To get specific DMO schema:
Step 4: Present Results
Parse and present the results in a user-friendly format:
For DLO List:
- Show DLO name, label, category, and ID
- Indicate total count
- Highlight DLOs with data (totalRecords > 0)
For DLO Schema:
- Show basic info (name, label, category, status)
- List all fields with:
- Field name
- Data type
- Primary key indicator
- Nullable status
- Highlight custom fields (exclude system fields like DataSource__c, cdp_sys_*)
- Show record count if available
For DMO List:
- Show DMO name, label, category, and ID
- Indicate total count
For DMO Schema:
- Show basic info (name, label, category, description)
- List all fields with:
- Field name
- Data type
- Primary key indicator
- Nullable status
- Show dataspace information if available
Step 5: Offer Next Steps
After displaying results, suggest relevant follow-up actions:
- Query data from the DLO
- Create calculated insights
- Build segments
- Set up data streams
- Create DMO mappings

Error Handling
Common Issues:
-
Org not connected
- Message: "Org not connected"
- Solution: Ask user to authenticate via SF CLI
-
DLO not found
- Message: "DLO 'XYZ__dll' not found"
- Solution: List all DLOs first to verify name
-
DMO not found
- Message: "DMO 'XYZ__dlm' not found"
- Solution: List all DMOs first to verify name
-
Permission issues
- Message: HTTP 403 errors
- Solution: Verify user has Data Cloud permissions
-
API version mismatch
- Current: v64.0
- Solution: Script can be updated for newer API versions
Example Usage
Example 1: List all DLOs
Example 2: Get specific DLO schema
Example 3: Explore DLOs then get schema
Example 4: List all DMOs
Example 5: Get specific DMO schema
Example 6: Explore DMOs then get schema

Notes
- DLO names always end with
__dllsuffix - DMO names always end with
__dlmsuffix - Field names always end with
__csuffix - System fields (DataSource__c, KQ_, cdp_sys_) are automatically added
- Primary key fields are required for DLO and DMO queries
- API supports pagination (limit/offset) for large result sets
