[python SDK] SDK doesn't seem to work with python3.8

[mohamedadel104]

docs state that it supports python3.8+

however, when using python3.8 import fails with: TypeError: 'type' object is not subscriptable

after an Ai discussion, basically the issue seems to be coming from

File: copilot-sdk/python/copilot/client.py
Line 137: def _parse_cli_url(self, url: str) -> tuple[str, int]:
Error: TypeError: 'type' object is not subscriptable

File: copilot-sdk/python/copilot/types.py
Line 89: parameters: Dict[str, Any] | None = None
Line 188: tools: NotRequired[List[str] | None]
Line 204: available_tools: list[str]
Line 206: excluded_tools: list[str]

after fixing those here to use 3.8+ compliant version, the issue seems to be fixed. source code needs accordingly

Thanks for reporting this issue, @mohamedadel104!

You've identified a legitimate compatibility bug — the Python SDK uses type hint syntax (tuple[str, int], list[str], | union operator) that was introduced in Python 3.9+, but the documentation claims support for Python 3.8+.

I've labeled this as bug and sdk/python. The maintainers will need to either:

• Update the type hints to use Python 3.8-compatible syntax (Tuple[str, int] from typing, Union, List, etc.), or
• Update the documentation to specify Python 3.9+ as the minimum version

Thanks for the detailed report with specific file and line references!

You are correct, the SDK requires 3.9. We're updating the documentation to reflect this.
