Breaks down plans, specs, or PRDs into tracer bullet issues that cut vertically through your stack instead of horizontal layer by layer work. Each issue is a thin end-to-end slice that can actually be demoed when done. It reads your existing issue tracker vocabulary, explores the codebase to match your domain language, then drafts a breakdown distinguishing between HITL work that needs human decisions and AFK work an agent can ship autonomously. You iterate on granularity and dependencies before it publishes real issues in dependency order. The focus on vertical slices over feature branches or layer work is the real value here, it forces you to ship testable increments instead of half built features waiting on integration.
