I'm good with this. I assume you've tested this more than I have!

The change looks straightfoward to me, but here's my context agent's review:

 1. copilot.session.PermissionRequestResult, ProviderConfig — replaces 3-tier try/except fallback
 2. copilot.tools.Tool — replaces try/except with None fallback
 3. _perm_result simplified — removes None guard, always constructs the real object

You're right that my earlier concern about downstream Tool is not None checks was speculative. Looking at the actual diff, there's no issue — the _tool_discovery.py code that uses Tool would just import it directly now.

Updated recommendation: This is a clean, low-risk improvement. The only real question is whether copilot.session and copilot.tools are stable import paths in SDK 0.2.0+. If Chris tested it, approve it. I'd just ask him to fill in the PR description with a one-liner about what changed.
