"""tool_use x Azure (Microsoft Foundry).
Drive the real `claude` CLI against a running LiteLLM proxy that routes
Claude requests to Anthropic's models hosted in Microsoft Foundry on
Azure, ask Claude to invoke a built-in tool (`Bash`), and assert that
the upstream returned a `tool_use` content block.
Foundry's Anthropic deployments support function/tool calling
identically to anthropic.com; LiteLLM's `azure_ai/claude-*` route
inherits the full Anthropic tool-use transformation.
The (feature, provider) for this cell is inferred from the file path by
`tests/claude_code/conftest.py`:
