Desktop agent picker doesn't show plugin-registered agents

[deantee]

Description

Plugin-registered agents don't appear in the Desktop agent picker. TUI and CLI show them correctly.

CLI output:

% opencode agent list 2>/dev/null | grep -E "^\w" | head -10
Sisyphus - ultraworker (primary)
Hephaestus - Deep Agent (primary)
Prometheus - Plan Builder (primary)
Atlas - Plan Executor (primary)
build (subagent)
compaction (primary)
explore (subagent)
general (subagent)
plan (subagent)
summary (primary)

Desktop sidecar log:

Plugins

oh-my-openagent@latest

OpenCode version

1.15.13

Steps to reproduce

1. Install a plugin that registers agents (e.g. oh-my-openagent)
2. Open the Desktop app and navigate to a project
3. Check the agent picker in the composer - only built-in agents appear
4. Run opencode agent list in terminal - plugin agents are listed correctly

This issue might be a duplicate of existing issues. Please check:

• [Desktop] Plugin-defined agents not showing in agent selector #28287: [Desktop] Plugin-defined agents not showing in agent selector — same symptom (plugin agents visible in CLI but not Desktop agent picker, with oh-my-openagent)
• v1.14.35 Desktop shows plugin loaded, but oh-my-openagent custom agents not visible in GUI (TUI works when launched from same exe) #25824: v1.14.35 Desktop shows plugin loaded, but oh-my-openagent custom agents not visible in GUI — same root cause area (Desktop sidecar not loading Bun-targeted plugins correctly)
• After update to v.14.37, in desktop app. Agent not showing up the plugin list. In CLI it is working fine. #25840: After update to v1.14.37, in desktop app agent not showing up the plugin list — same symptom with a different plugin

If your issue is distinct (e.g. the Bun.serve error in the sidecar log is a new angle), please add a note explaining how it differs from the above.
