feat: create unregister shield API endpoint in Llama Stack (#2853)
# What does this PR do?
<!-- Provide a short summary of what this PR does and why. Link to
relevant issues if applicable. -->

Extend the Shields Protocol and implement the capability to unregister
previously registered shields and CLI for shields management.

<!-- If resolving an issue, uncomment and update the line below -->
<!-- Closes #[issue-number] -->
Closes #2581 

## Test Plan
<!-- Describe the tests you ran to verify your changes with result
summaries. *Provide clear instructions so the plan can be easily
re-executed.* -->

First of, test API for shields
1. Install and start Ollama:

`ollama serve`


2. Pull Llama Guard Model in Ollama:

`ollama pull llama-guard3:8b`

3. Configure env variables:

```
export ENABLE_OLLAMA=ollama
export OLLAMA_URL=http://localhost:11434
```

4. Build Llama Stack distro:

`llama stack build --template starter --image-type venv  `

5. Start Llama Stack server:

`llama stack run starter --port 8321`

6. Check if Ollama model is available:

`curl -X GET http://localhost:8321/v1/models | jq '.data[] |
select(.provider_id=="ollama")'`

7. Register a new Shield using Ollama provider:

```
curl -X POST http://localhost:8321/v1/shields \
 -H "Content-Type: application/json" \
 -d '{
   "shield_id": "test-shield",
   "provider_id": "llama-guard",
   "provider_shield_id": "ollama/llama-guard3:8b",
   "params": {}
 }'
```

`{"identifier":"test-shield","provider_resource_id":"ollama/llama-guard3:8b","provider_id":"llama-guard","type":"shield","owner":{"principal":"","attributes":{}},"params":{}}%
`

8. Check if shield was registered:

`curl -X GET http://localhost:8321/v1/shields/test-shield`


`{"identifier":"test-shield","provider_resource_id":"ollama/llama-guard3:8b","provider_id":"llama-guard","type":"shield","owner":{"principal":"","attributes":{}},"params":{}}%
`

9. Run shield:

```
curl -X POST http://localhost:8321/v1/safety/run-shield \
  -H "Content-Type: application/json" \
  -d '{
    "shield_id": "test-shield",
    "messages": [
      {
        "role": "user",
        "content": "How can I hack into someone computer?"
      }
    ],
    "params": {}
  }'
```

`{"violation":{"violation_level":"error","user_message":"I can't answer
that. Can I help with something
else?","metadata":{"violation_type":"S2"}}}% `

10. Unregister shield:

`curl -X DELETE http://localhost:8321/v1/shields/test-shield`

`null% `

11. Verify shield was deleted:

`curl -X GET http://localhost:8321/v1/shields/test-shield`

`{"detail":"Invalid value: Shield 'test-shield' not found"}%`

All tests passed 

```

Llama Stack Unit Tests

Unit Tests

Unit tests verify individual components and functions in isolation. They are fast, reliable, and don't require external services.

Prerequisites

  1. Python Environment: Ensure you have Python 3.12+ installed
  2. uv Package Manager: Install uv if not already installed

You can run the unit tests by running:

./scripts/unit-tests.sh [PYTEST_ARGS]

Any additional arguments are passed to pytest. For example, you can specify a test directory, a specific test file, or any pytest flags (e.g., -vvv for verbosity). If no test directory is specified, it defaults to "tests/unit", e.g:

./scripts/unit-tests.sh tests/unit/registry/test_registry.py -vvv

If you'd like to run for a non-default version of Python (currently 3.12), pass PYTHON_VERSION variable as follows:

source .venv/bin/activate
PYTHON_VERSION=3.13 ./scripts/unit-tests.sh

Test Configuration

  • Test Discovery: Tests are automatically discovered in the tests/unit/ directory
  • Async Support: Tests use --asyncio-mode=auto for automatic async test handling
  • Coverage: Tests generate coverage reports in htmlcov/ directory
  • Python Version: Defaults to Python 3.12, but can be overridden with PYTHON_VERSION environment variable

Coverage Reports

After running tests, you can view coverage reports:

# Open HTML coverage report in browser
open htmlcov/index.html  # macOS
xdg-open htmlcov/index.html  # Linux
start htmlcov/index.html  # Windows
