What are AI subagents in coding?

AI subagents are autonomous instances spun from tools like Copilot CLI, each handling one task (e.g., fix an issue) in isolation, enabling parallel work on codebases.

How do git worktrees work with AI agents?

Git worktrees create separate filesystem folders for different branches in one repo, letting multiple AI subagents code simultaneously without conflicts.

Will AI subagents replace developers?

Not fully — they accelerate fixes and maintenance, but humans still triage, review, and architect. Juniors might get sidelined in routine tasks, though.
