Bug Description

This issue persists for me even after updating everything. I am using WSL.
#3138

Header 'x-opencode-agent-name' has invalid value: '​Atlas (Plan Executor)'

I tried updating my .config/opencode/opencode.json and switched the plugin from oh-my-openagent to oh-my-opencode and then when I launch opencode i see the newer names with dashes but those fail w/ the same error:
Header 'x-opencode-agent-name' has invalid value: '​Sisyphus - Ultraworker'

Sisyphus works when i dont do this. its Atlas that repeatedly doesnt work.

Steps to Reproduce

Setup omo and opencode on WSL
Connect to providers - OpenAI, Claude, and Gemini
Run opencode
Create a plan with Prometheus (Opus 4.6)
/start-work

Expected Behavior

I expect Atlas to run. Other agents are working.

Actual Behavior

Fails with the following error:
Header 'x-opencode-agent-name' has invalid value: '​Atlas (Plan Executor)'
