Use when a room, arena, hunt, ambush or non-boss challenge needs an explicit state/beat graph, entry/exit rules, composition goals and evidence without forcing one universal encounter shape.
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
# Encounter design Ask the intended role: traversal pressure, teaching, resource test, elite challenge, ambush, arena, hunt, hybrid, or existing. ## Contract Publish: - stable `encounter_id` and revision - goal and completion condition - state/beat graph with stable beat IDs - participant/spawn references - entry, fail, retry, reset and exit policy - resource assumptions and rewards only if the project uses them - evidence needed to prove the authored goal ## Ownership Encounter design composes existing systems. `spawn-wave` owns dynamic spawn scheduling, `enemy-kit-balance` owns kits, `difficulty-design` owns scaling policy, and loot/economy systems own grants. ## Rules 1. An encounter may test one concept or several interacting concepts; composition is authored, not universally capped at one idea. 2. HP, count, geometry, information and resource pressure are valid only when tied to the stated goal and owner contracts. 3. Rewards are optional project data; do not require a drop to compensate a spend. 4. Reset/retry transitions are idempotent and do not duplicate participants or grants. …

How to install
mdr add jammyfu/open-game-skills/encounter-design@sha256:f7b9974cc931a206The line at the top of this page pins the label git:20260913.d5b76f6, 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.
