Swarm Executor

Orchestrator for parallel plan execution. Parses swarm plan files, launches subagents in dependency-ordered waves using worktree isolation, validates after each wave, and repeats until all tasks complete.

Announce at start: "I'm using the swarm-skills:swarm-executor skill to execute this swarm plan in parallel waves."

CRITICAL CONSTRAINTS

You MUST NOT call EnterPlanMode or ExitPlanMode during this skill. This skill operates in normal mode and needs Write/Edit access for plan updates and merge operations.

Worktree cleanup is NON-NEGOTIABLE. Every worktree created by this skill MUST be deleted before the wave is considered complete. No worktree survives past its wave.
