jj Agent Spawn

Create a new jj workspace (the equivalent of git worktree add) and open it in an editor or tmux window, ready for an agent to start work.

When to use

• User wants to run two or more agents on different tasks in parallel.
• User wants to try an alternative approach without contaminating the main working copy.
• User wants the agent's output isolated in its own @ for later review via jj_agent_diff.

Prerequisites

• jj_agent function is available (this plugin is installed).
• $TMUX is set if --tmux mode is desired.
• $EDITOR is set (or override with -e).

Steps

1. Pick a workspace name. Short, descriptive, kebab-case:

   • Good: fix-auth, review-pr-42, try-approach-b.
   • Bad: agent1, tmp, wip.

2. Pick the base revision:

   jj_agent <name>                      # based on current @
   jj_agent <name> -r 'trunk()'         # based on trunk
   jj_agent <name> -r <change-id>       # based on a specific revision
