Use when world time changes lighting, schedules, availability, stealth, spawning or other systems and the project needs one versioned clock contract with explicit consumers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Day night Ask the mode: cosmetic, scheduled-world, gameplay-linked, externally-driven, hybrid, or existing. ## Contract Publish: - stable `time_cycle_id` and revision - clock source and time scale/pause policy - canonical time state and boundary definitions - stable transition identity for dawn/day/dusk/night or project equivalents - persistence/suspend behavior - list of authorized effect consumers ## Ownership `day-night` owns canonical world-time state and transition events. Lighting, spawn schedules, stealth, weather, quests and audio consume that state through their own skills. It does not rewrite combat clocks or save bytes. ## Rules 1. A transition is emitted once for a given state boundary/revision; resume or duplicate callbacks cannot replay it accidentally. 2. Time skips, sleeps and scripted jumps declare source and resulting transition sequence. 3. Save/load restores canonical time plus policy revision; presentation interpolations are not the source of truth. 4. Systems may ignore world time or depend on it according to project policy; neither choice is universal. ## Acceptance …

How to install
mdr add jammyfu/open-game-skills/day-night@sha256:9124572286a4a4baThe line at the top of this page pins the label git:20260913.6102fc3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
