Bug Description

When I switch the agent to Orchestrator-Sisyphus, a prompt always pops up in the top-right corner saying, “Agent orchestrator-sisyphus's configured model anthropic/claude-sonnet-4-5 is not valid.”

I configured a custom model for the orchestrator-sisyphus agent.

Steps to Reproduce

1. Configure a custom model for orchestrator-sisyphus.
2. Launch Open Code.
3. Switch the agent to Orchestrator-Sisyphus.
4. A notification appears in the top-right corner: “Agent orchestrator-sisyphus's configured model anthropic/claude-sonnet-4-5 is not valid.”

Expected Behavior

If a model is configured for orchestrator-sisyphus and the model is available, the message “Agent orchestrator-sisyphus's configured model anthropic/claude-sonnet-4-5 is not valid.” should not appear.

Actual Behavior

Regardless of whether the orchestrator-sisyphus model configuration is valid, every time I switch to the Orchestrator-Sisyphus agent, a notification always appears in the top-right corner: “Agent orchestrator-sisyphus's configured model anthropic/claude-sonnet-4-5 is not valid.”
