opencode and killo code authentication problem when using acp, for agents

**Steps to reproduce**
1. Go to 'agents in settings'
2. Click on 'clikc on opencode'
3. it will not detect it
4. and when i added both kilo and opencode as custome agents, i get auth problems, i was unable to unthenticate reguest and agents where not able to chat
5. and hermis works fine, but not able to chat, becuase of env problmes with secrete key not set while have set it globally [ linux ubuntu ]
