Openspec Apply Change

You point it at a change (or let it infer from context), it reads the relevant artifacts like specs and design docs, then works down the checklist until it's done or hits something unclear. The nice bit is it's not rigid about workflow phases. If implementation surfaces a design problem, it'll pause and suggest updating artifacts rather than bulldozing ahead. Supports different OpenSpec schemas, not just the spec-driven one. Good for when you've got a plan broken into tasks and want Claude to execute methodically rather than wandering off into creative refactoring land.
