sprint

The runner / front door. Designing happens in sprint-plan (it leaves a plan.json wave schedule + GitHub issues). This skill takes an approved sprint and drives it to completion — one issue at a time, reconciling real state from GitHub before every step, so it's always safe to stop and re-enter.

Everything is GitHub (issues = work, PRs = delivery) + the repo's .claude/sprints/sprint-N/. No cluster, no external tracker, no private infra.

Two hard rules

1. No git action without an explicit mode. Before anything touches a branch, PR, or merge, the user must choose HITL or AFK (below). Never assume one.
2. One Claude instance at a time. Issues run strictly sequentially. That serialization is what lets the agent rebase + merge safely — nothing else is touching the tree, so nothing gets lost.

When invoked — dispatch on state
