deck-build SKILL.md skillA
deck-build from jammyfu/open-game-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jammyfu/open-game-skills/deck-build@git:20260913.baf5cadPins git:20260913.baf5cad in mdr.lock. Pin the fingerprint instead.

Use when cards or card-like actions move through a deck/hand/discard/exhaust system and the project needs stable card identity, zone transactions, draw/shuffle rules and replayable RNG ownership.
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
# Deck build Ask the deck model: fixed, constructed, draft, run-builder, rotating-pool, hybrid, or existing. ## Contract Publish: - stable `deck_ruleset_id` and revision - stable `card_id` plus card-definition revision - legal deck constraints - canonical zone IDs and move rules - draw/shuffle/mulligan policy - cost/resource owner references - `rng-seed` stream reference for stochastic ordering - persistence/reset behavior ## Ownership This skill owns deck composition rules and card movement between canonical zones. Card effects route to their gameplay owners; resources route to their own meter/economy skill; RNG algorithm/state stays in `rng-seed`. ## Rules 1. Each zone transition has transaction/request identity so duplicate callbacks cannot draw, discard or exhaust the same card twice. 2. Shuffle/draw order is reproducible from declared stream state when determinism is required. 3. Starter viability, encounter order and required content are project policies, not deck-system invariants. 4. Card display order/animation is not canonical zone order unless explicitly authored. 5. Ruleset changes increment revision and define migration for persisted decks/runs. ## Acceptance …

How to install
mdr add jammyfu/open-game-skills/deck-build@sha256:9bf59475289f16fbThe line at the top of this page pins the label git:20260913.baf5cad, 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.
