implement-plan

v1.13.0

Use when the user has an agreed plan — a visual plan, a plan-mode plan, a plan file, or a design agreed in chat — and asks to implement, execute, build, or "do the work we agreed on", especially when the work is big enough to split across subagents and worktrees, must be checked against the plan afterwards, and must run mostly hands-free.
