Crash when local.agent.current() returns undefined during startup/auth

[tdawe1]

Description

OpenCode crashes with TypeError: undefined is not an object when:

1. Using authentication plugins like opencode-antigravity-auth
2. The agents array is empty or not yet loaded during startup

Stack Traces

TypeError: undefined is not an object (evaluating 'local.agent.current().name') at (src/cli/cmd/tui/component/prompt/index.tsx:840)

TypeError: undefined is not an object (evaluating 'a6.name')
at (src/cli/cmd/tui/context/local.tsx:151)

Root Cause

Multiple places in prompt/index.tsx and local.tsx access .name on potentially undefined objects.

Environment

• OpenCode version: 1.1.13
• OS: Arch Linux

All of these involve the same error: 'local.agent.current()' returning undefined, occurring during authentication or provider connection. They all share similar stack traces pointing to prompt/index.tsx:840.

Feel free to ignore if this addresses your specific case differently than these others.
