  • Auto-invoked when a task matches, or called by name
  • Capture any session as a new skill with /skillify

Q&A

the Code Agent asks the right questions to nail the details.

  • Ambiguous tasks get a quick multiple-choice
  • Pick a design direction, a framework, or a schema
  • Answers flow straight into the plan

Subagents

Subagents run in parallel to research, build, and review at once.

  • the Code Agent delegates larger tasks to specialized subagents
  • Each child runs in parallel with its own context window
  • Deep worktree support — launch subagents in their own worktrees
