Hi @pisv, thanks for the update, much appreciated!
I noticed a one small thing missing: when a new custom agent is created via the AI configuration view, the template’s description (and name) are not localized yet. The prompt itself is fine though I guess, consistent with the other agents like Coder.

See packages/ai-core/src/browser/frontend-prompt-customization-service.ts

@ndoschek Thanks once again for your thorough review, much appreciated!

I've tried to address your comments in 9f469c0.

I'm not quite sure whether the name in newCustomAgentEntry should be localized, since both the name and the prompt don't seem to be localized for other agents like Coder.

Please let me know if you think that the name needs to be localized in this instance.

Thanks for the quick update @pisv 🎉
Agreed, it's consistent to leave the name as is.

LGTM 👍
