Use when a boss or major encounter needs a clear exam, phase/state structure, authored risk/readability policy and recoverable transitions without copying a shipped encounter or forcing universal phase rules.
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
# Boss design Ask the project role first: duel, puzzle-gate, hunt, raid, spectacle, hybrid, or existing. ## Contract Publish: - stable `boss_encounter_id` and revision - exam/goal statement - phase or state graph with stable state IDs - entry/exit/fail/retry policy - authored risk/readability policy - arena dependencies and required taught verbs - resource/reset rules owned by their respective systems ## Ownership Boss design owns encounter composition and state transitions. `attack-tell` owns warning contracts, `enemy-kit-balance` owns move-kit tuning, `difficulty-design` owns difficulty policy, and camera/combat/resource skills retain their own truth. ## Rules 1. Telegraph/readability is authored from threat, pacing, player capability and accessibility needs; there is no universal damage-to-windup formula. 2. A phase may change space, goals, move combinations, resources, presentation or another authored dimension; it does not need to fit one template. 3. Required tools/verbs must have a recoverable availability path or an explicit fail/retry path. 4. Story placement, optionality and relative difficulty are project progression decisions, not boss invariants. …

How to install
mdr add jammyfu/open-game-skills/boss-design@sha256:049e6b8dbc5a29f6The line at the top of this page pins the label git:20260913.6c938b4, 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.
