What's Wrong?

This morning, I tried a run with the new auto mode as a test. Then I kept on going with my day with my normal security settings and Claude bypassed plan mode and edited files on my system.

What Should Happen?

Here are the things that should happen:

• Plan mode should be respected
• Anthropic needs to allow people to use OpenCode with their subscriptions
