"""
agent_tools.py — Facade module.

Re-exports tool parsing, schemas, execution, and implementations
for backward compatibility. All importers continue to work unchanged.

Sub-modules:
  - tool_parsing.py: regex patterns, parse/strip functions
  - tool_schemas.py: FUNCTION_TOOL_SCHEMAS, function_call_to_tool_block
  - tool_execution.py: execute_tool_block, format_tool_result, MCP helpers
  - tool_implementations.py: all do_* tool functions
