Background Task Router

Usage

• /bg <task> — type the slash command followed by the task
• [bg] <task> — inserted automatically by ctrl+b keybinding, then submit

Behavior

1. Strip /bg or [bg] prefix
2. Spawn immediately:

   Agent({
     description: "<3-word task>",
     prompt: "<task> — Caveman terse output. Return result only.",
     run_in_background: true
   })
   

3. Output one line: → BG: <3-word task>
4. Return to main thread immediately. Do not wait. Do not narrate.

Rules

• Never block main thread waiting for the spawned agent.
• Never output more than one confirmation line.
• Ambiguous task = spawn anyway. Background agents can resolve in context.
• Multiple [bg] prefixes in one message = multiple parallel spawns (one Agent call per task).
• Always use run_in_background: true. Never omit it.
