You start an agent at 11pm with a task list and go to bed. Two things can go wrong while you are asleep. It spends far more than you planned, or it works all night and hands you code that never ran a single test. Nightshift Pro puts a hard ceiling on the first and a closed gate in front of the second.
You bring your own agent. The pack has no opinions about your code and cannot write any of it, so what you are buying is the safety wiring around a loop you already run. Eight small tools, Python and bash, standard library only. Nothing to install, no service to sign up for. Put bin on your PATH and wire it into however you already launch things.
cost-governor keeps a running dollar ledger against a budget you set. It logs a warning when you cross the warn line and drops a stop file when spend crosses the ceiling. Give it a one dollar ceiling, feed it units of 50, 35 and 40 cents, and it halts the run at 1.25 with a ledger showing where every entry went.resume-controller wraps one unit of agent work. It backs off and retries on a rate limit (one second, then two, then four), retries a genuine crash a bounded number of times, and escalates when it cannot recover instead of quietly eating the rest of the night.verify-gate runs the checks you name in your config, each with its own timeout, and fails closed. Every run writes a JSON report with the exit code, the elapsed seconds and the tail of the output for each check. A closed gate escalates.morning-brief turns the night into one page with the verdict on the first line. Then the decisions waiting on you, then real spend pulled from the ledger, then what actually got finished.escalate sends a desktop notification, an email or a webhook post from a single config block.runaway-guard halts the loop on an iteration cap, a wall clock deadline, a stop file, an over budget signal, or the same task marker repeating too many times in a row.nightshift-run is the orchestrator that runs all of the above as one loop. It can commit after each accepted unit, so the whole night reads back as one commit per unit of work.nightlog appends the structured events that the other tools read.You also get a guide of about 5,000 words in fifteen sections, a worked example that drives a real agent CLI with the spots you need to change marked in the file, a demo that runs the whole pack in a throwaway directory in a few seconds, and a 28 test regression suite that locks the safety behavior in place.
The ledger is manual. You feed it the numbers your run reports. It cannot read your provider's live bill, so it is exactly as accurate as what you record.
The ceiling can overshoot by up to one unit's cost. Budget is checked after each unit is recorded, which is why a one dollar ceiling can finish at 1.25. That overshoot shows up as an ordinary ledger entry.
Prices are yours to supply. The config template ships placeholder per token numbers, because we cannot know what your provider charges you. Put your real published numbers in or you get a confidently wrong ledger.
The email channel has not been tested against a live mail server. The SMTP code is there and the config documents it, but we have not run it against a real provider. Desktop and webhook are plain standard library calls and both work. Do a test send to yourself before you rely on email overnight.
Most of the ideas here are in the free kit, which is on GitHub under MIT: four habits and four small bash tools, a runaway guard and a morning brief among them. It does the job on its own. If the free four fix your nights, keep your 79 dollars. We would rather you did that than buy something you do not need.
The paid pack is for after you have been running agents unattended long enough that the rough edges start costing real money. Free stops a bad night by counting iterations and clock time. Neither of those knows what the night cost, and neither survives a rate limit without you awake to notice.
