Hey, this is a known bug. Plugin commands load, but the slash menu keeps a stale cache until you reload the window. We’re tracking the issue, but I can’t share an ETA for a fix yet.
Workaround: reload the window via Cmd+Shift+P → Developer: Reload Window or Cmd+Shift+R. After that, / should pick up the plugin commands.
Similar reports for context: Skills visible in Settings but not appearing as slash commands in Agent chat and Slash command suggestions disappear after conversation starts
If the commands still don’t show up after a reload, let me know and we can dig deeper.
