Description

This PR addresses two improvements to the safeguards commands:

1. Help text verb tense fix: Updated examples in _create.py, _delete.py, and _show.py to use first-person imperative verbs per Azure CLI guidelines (e.g., "Create" instead of "Creates").

2. Pre-existence validation: Added a check in az aks safeguards create to prevent duplicate resource creation. The command now:

   • Checks if a Deployment Safeguards resource already exists before attempting to create
   • Returns a clear error message directing users to az aks safeguards update or az aks safeguards delete
   • Supports both -g/-n and --managed-cluster URI syntax

Testing

• Tested create when resource doesn't exist (succeeds)
• Tested create when resource exists (blocks with helpful error)
• Tested with both -g/-n and --managed-cluster URI syntax
• Verified error message guides users to correct commands

General Guidelines

• Have you run azdev style <YOUR_EXT> locally? (pip install azdev required)
• Unable to run: azdev requires a full Azure CLI development environment with both azure-cli and azure-cli-extensions repos configured via azdev setup. This PR contains help text changes in AAZ-generated files and validation logic. The CI pipeline will validate this automatically.
• Have you run python scripts/ci/test_index.py -q locally? (pip install wheel==0.30.0 required)
• My extension version conforms to the Extension version schema

For new extensions:

• My extension description/summary conforms to the Extension Summary Guidelines.

Hi @ShantingLiu, since you've updated the argument value in the test case, please make sure to update the value in the recording files as well so the CI checks can pass.

The current recordings are still not passing the CI checks. I have re-queued the live test for the safeguard-related tests. If the live test passes, you can download the new recording files from the pipeline artifact, and they should pass the CI.

Blocked by a failing test that is unrelated to the Safeguard changes. Working with the cli team to see how to proceed. #9575 #9530
