Thanks so much for this. I've added a couple of comments.

Also, can we reuse the OpenAI adapter for the handlers? Like what I've done with copilot and openai_compatible adapters? It may prevent us requiring an additional test and will make the adapter logic that much easier.

Sure, I actually started with that approach following the xAI adapter, but for some reason, it didn’t work. I might have had something else interfering with the code at the time. Now, everything runs using the OpenAI adapter.

One more thing: I resolved the conversations for the two reviews. I’m not sure if that’s the correct approach or if it’s something you’re supposed do the resolve conversation. Apologies if I overstepped, I don’t have much experience with PRs.

Looks fantastic, thank you. Feel free to drop the test as we have it all covered with the OpenAI one.

done, tests dropped.

Thanks so much for this. Feels great to have this in CodeCompanion finally.
