Use when verified purchases, subscriptions, durable unlocks, consumables, or time-limited access must be granted exactly once across retries, crashes, duplicate callbacks, and multiple devices.
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
# Entitlement grant This skill owns verified purchase-event → durable entitlement state. Store UI and pricing belong elsewhere; `restore-purchase` owns user-initiated/current-entitlement reconstruction. ## Product classes | Class | Durable state | |---|---| | non-consumable/durable-unlock | boolean/ownership keyed by product plus store identity | | consumable | balance mutation keyed by a unique transaction/purchase token/event id | | subscription/time-pass | entitlement interval/status keyed by the store's stable subscription identity/token | | battle-track/season | ownership scoped to season/content identity | ## Idempotent transaction state machine Use the immutable store transaction ID, purchase token, or equivalent verified event ID as the deduplication key; do not use UI callbacks or order display strings as the primary key. A safe abstract flow is: 1. receive `pending`/purchased event and persist processing state; 2. verify authenticity/account/product and confirm it is grantable; 3. in one durable transaction, record the event ID and apply the entitlement/balance mutation if that event ID is not already committed; …

How to install
mdr add jammyfu/open-game-skills/entitlement-grant@sha256:662578bf33f27b38The line at the top of this page pins the label git:20260913.51c1b6d, 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.
