One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.

1 of 5

Prompt

We have multiple subscriptions under a single management group 'mg-corp-prod'. Instead of querying each subscription individually, I want to execute a single HTTP request to fetch aggregated historical spending across all subscriptions in that group. What exact scope path and API endpoint should I submit my POST payload to?

What was checked, without and with the skill

Uses scope path /providers/Microsoft.Management/managementGroups/<id>	Passed	Passed
Uses query endpoint POST {scope}/providers/Microsoft.CostManagement/query?api-version=2023-11-01	Missed	Passed
