Of course it can, it's Microsofty tactics, support everything but generate "proprietary" stuff by default. Read ODF but generate docx.

works the other way as well, i have my opencode.jsonc which declares what model an agent should use, and it points at .claude/agents/ those agents each have their anthropic based model instead, almost feel like this broke in the past week though for just cc, hard to tell as cc keeps changing and i dont wanna update and learn more claude based nonsense again, if i wasn't locked into a year of pro or whatever, I would 100% be done using them entirely.
