# pallets__flask-5063
# Loki Mode Multi-Agent Patch
# Attempts: 1

This appears to be a benchmark repository, not the Flask source code. I need to generate a patch for the Flask repository (pallets/flask). Let me look at the Flask source code from my knowledge of the Flask codebase to generate the appropriate patch.

Based on the issue description and the architect's analysis, I need to modify the `routes_command` function in `src/flask/cli.py` to add subdomain/domain information to the output.
