Naming Rules Drift Check

Procedure

1. Select resources to check

If a specific list is provided, use it. Otherwise, select a batch of resources:

python3 -c "
import json
with open('resourceDefinition.json') as f:
    resources = json.load(f)
# Select resources with official namespace (can verify against docs)
official = [r for r in resources if r.get('official', {}).get('resource_provider_namespace')]
for r in official[:20]:  # Check 20 at a time
    ns = r['official']['resource_provider_namespace']
    print(f'{r[\"name\"]}|{ns}|{r[\"min_length\"]}|{r[\"max_length\"]}|{r[\"scope\"]}')
"

2. Fetch current Azure naming rules

For each resource's resource_provider_namespace, look up the naming rules:

URL: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/resource-name-rules

Use Microsoft Docs MCP tools (microsoft_docs_fetch) to fetch and parse the rules page. Find the section matching the resource provider namespace.

3. Compare

For each resource, compare:

• min_length vs documented minimum
• max_length vs documented maximum
• scope vs documented scope
• dashes vs whether hyphens are documented as valid
• lowercase vs whether only lowercase is documented
• validation_regex vs pattern derived from documented valid characters

4. Report
