Copilot CLI 1.0.101 adds structured output for workflow subagents and stops local models blocking Auto
The Oct 20 release gives dynamic workflow subagents native structured output on supported models, adds an assistedApprovalInstructions setting to steer Assisted Permissions, and stops local or loopback providers in providers.json from overriding Auto or your saved model. It also makes headless and SDK sessions skip MCP servers whose saved tokens need interactive sign in, and fixes the first prompt hanging silently when no model is selected…
