Re-fetch Azure naming rules for a set of resources and compare against current regex/length/scope values in resourceDefinition.json.

  • : periodic audit
  • Calls python3; reaches learn.microsoft.com
  • Resource validation

What it does

Naming Rules Drift Check is an agent skill from aztfmod/terraform-provider-azurecaf. Re-fetch Azure naming rules for a set of resources and compare against current regex/length/scope values in resourceDefinition.json. Detects when Azure has changed naming constraints. Triggers on: periodic audit, resource validation.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud. It works with Microsoft Azure. The repository describes itself as: Terraform provider for the Terraform platform engineering for Azure. The licence is MIT.

When your agent uses it

  • : periodic audit
  • Resource validation

Example prompts

  • “/naming-rules-drift-check”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Select resources to check
  2. Fetch current Azure naming rules
  3. Compare
  4. Report

What it can do on your machine

Read from SKILL.md and the folder at commit ac74615. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • learn.microsoft.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Naming Rules Drift Check loads about 507 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 105 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~507

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Naming Rules Drift Check

Procedure

1. Select resources to check

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

bash
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
## Naming Rules Drift Report

| <name>   | max_length | 63 | 128 | Update |

### Verified Resources (<count>)
All other checked resources match Azure documentation.

### Summary
