Additional Information

I created a Claude code routine with a trigger on Github PR open at https://claude.ai/code/routines successfully.
It says:

Repositories
openwrt/openwrt
Triggers on
openwrt/openwrt
Pull request opened

There are no filters configured.
I am did not connect this github account to Claude, but @openwrt-ai.
The routine is never triggered.

There are new PRs showing up: https://github.com/openwrt/openwrt/pulls

In the beginning I had the Claude code account connected to the @hauke github account. There one routine run was successfully triggered.
The Claude code app is installed in the @openwrt-ai account and the @openwrt organization.
The user @openwrt-ai has triage permissions on the https://github.com/openwrt/openwrt repository.

I removed the routine and created it again, did not help.
I disconnected the github account and connected it again, did not help.
