Cortex-Inara/cortex/tools/__init__.py

"""
Orchestrator tool registry.

Each tool has two parts:
  1. A Gemini FunctionDeclaration — tells the model what the tool does and what args it takes
  2. A Python async callable — the actual implementation

To add a new tool:
  1. Implement it in a tools/<domain>.py module
  2. Import it here and add (declaration, callable) to _REGISTRY
  3. Add a FunctionDeclaration below and include it in TOOL_DECLARATIONS

IMPORTANT: These tools are separate from the ae_* MCP tools used by the fleet agents.
           Do not modify the ae_* MCP server to support orchestrator needs.
