"""AST-based smoke test for all plugin tools.

Why AST and not import? The /a0/ framework root is a namespace package
(no __init__.py) and cannot be reliably imported from a standalone venv.
AST parsing avoids the venv/sys.path issue while still verifying:
  - file parses cleanly (no syntax errors)
  - module defines exactly one Tool subclass
  - class name matches expected convention (CamelCase of module name)
  - class inherits from framework Tool base
  - class defines `async def execute(self, **kwargs) -> Response`
  - the execute() signature is `async def execute(self, ...)`

Run from the plugin root:
  python3 scripts/test_all_tools.py
