# parallel-execution

Cheap keys: lifecycle moment — before spawn, while creating worktrees, or at merge.

1. Before spawning any parallel worker: MUST Read `references/wave-safety.md`. Do not spawn without it.
2. When creating git worktrees/branches: MUST Read `references/worktrees.md`. Skip if not creating worktrees.
3. Before accepting merge of parallel work: MUST Read `references/verify-skills.md`. Skip at spawn time.
4. When parallel members share ONE working tree (no worktrees): MUST Read `references/shared-tree.md`. Skip when every member has its own worktree.
