Check Query Packs for Deprecated Resource Usage

Audit MQL query pack files (*.mql.yaml in content/) against the provider .lr resource definitions to find queries that reference deprecated resources or fields.

Steps

1. Collect all deprecated items from .lr files

Search all providers/*/resources/*.lr files for comments containing "Deprecated" (case-insensitive). For each match, extract:

  • The resource name (e.g., microsoft.organizations)
  • The field name if it's a field deprecation (e.g., createdTime)
  • What replaces it (from the deprecation comment)

Use Grep to find lines with // Deprecated or / Deprecated in .lr files, then read surrounding context to get the resource/field names.

2. Determine which mql.yaml files to check

  • If $ARGUMENTS is provided, check only that file
  • Otherwise, find all *.mql.yaml files under content/

3. Cross-reference queries against deprecated items

Read each mql.yaml file and examine every mql: block. Check if any deprecated resource name or field appears in the query string. Be thorough:

  • Check for resource names like microsoft.organizations
  • Check for field access like .createdTime, .vpcId, .staticWebsiteHosting
  • A field like createdTime on aws.s3.bucket would appear as something accessing .createdTime in a query that operates on s3 buckets

4. Report findings

For each deprecated usage found, report in a markdown table:

  • File path
  • Query UID
  • Deprecated usage (the exact text in the query)
  • Replacement (what it should be changed to)

If no deprecated usage is found, say so.

Do NOT make any changes to files. This skill is read-only — it only reports findings.
