pi-git-worktree

Create multiple worktrees with the same implementation spec, then dispatch subagents to execute them in parallel and compare results. Use when the user says "task variants", "try variants", "run variants", "compare implementations", "best of n", "compare approaches", or "same spec, different models". Requires pi-subagents installed. Composes with git-worktree-task-dispatch: dispatch the variants to execute, then compare results.

Dispatch parallel subagents to implement git-worktree-spec.md files across persistent worktrees. Use when the user wants to execute all worktree specs in parallel, implement multiple branches at once, dispatch agents to worktrees, or batch-run feature specs. Also accepts --model to use a specific model for all agents (e.g. after running git-worktree-task-variants, use that winning model for all worktrees). Triggers on "implement all worktrees", "run all specs", "dispatch to worktrees", "parallelize implementation".

Use when the user wants to break a project into independent parallel workstreams. Analyzes the repo, proposes a split plan with branches and specs, and creates persistent worktrees with the bundled script. Triggers on "break this down", "tasks breakdown", "split this work", "parallelize", "work on X and Y in parallel", or when they want to plan multiple features or branches.
