nightshift

Stand up and run a Nightshift shift: start the Turnstile coordination daemon, author and register a plan (orders.json → a DAG of landable-PR "orders"), keep the ready set live, land merged orders to unblock their dependents, and drain or stop the shift. Use this when asked to set up, register, drive, or wind down a Nightshift backlog (the operator/coordinator side, not the worker side).

Build one Nightshift order into a set of commits on its branch: make the change within the order's declared file scope, keep the claim alive with `nightshift check` before every commit, and use the required commit trailers. You never push; you hand the branch back. Use this when a Nightshift worker dispatches you to build (or rework) a single order.

Review one Nightshift order's diff as an independent adversarial reviewer: work read-only in the prepared worktree at the exact head, report only high-confidence bugs with file:line — each classified blocking, non-blocking, or pre-existing — and hand your findings back to whoever dispatched you. Use this when a Nightshift worker dispatches you to review an order.

Operate as a Nightshift night-shift worker: claim one unit of work (an "order" = one landable PR) from the Turnstile coordination kernel and take it to a reviewed branch — building it and reviewing it (usually by spawning subagents), driving the adversarial gate to two clean, then handing it back. Use this whenever you are launched to work a Nightshift backlog, or told to "run nightshift", "take the next order", or "join the shift".
