Tools

Default safe tools:

Name	Behavior
echo	Returns the provided text
list_files	Lists entries under tools.list_files_root (no writes)

When the request includes tools (or you set mock_tool_rounds), the mock may emit 0–10 tool-call rounds. Results are included under mock_my_ai.tool_rounds and the first round is mapped into provider-native tool_calls / tool_use / functionCall fields.

Not included by default: shell write, delete, arbitrary network.
