What is af?
Agent Farm CLI — the tool for spawning builders, managing Tower, workspaces, and cron tasks. ALWAYS consult this skill BEFORE running any `af` command to get the exact syntax. This prevents wasting time guessing flags that don't exist. Use this whenever you need to spawn a builder, check status, send messages, clean up worktrees, manage Tower, or run cron tasks. If you're about to type `af` followed by anything, check here first. Source: cluesmith/codev.
