Use when access depends on a capability, story predicate, or both, and the project needs a stable gate identity, deterministic predicate evaluation, unlock migration, and explicit soft-lock/recovery evidence.
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
# Ability gate Ask: `none | tool-gate | story-flag | both`. ## Ownership The gate consumes capability/story state from their true owners. It does not own tutorials, map pins, save storage or rest-site placement. ## Contract Each gate publishes: - stable `gate_id` - required capability IDs and/or story predicate IDs - predicate version - open/closed/blocked result - optional authored feedback/reference IDs Evaluate the gate from authoritative state. Duplicate unlock notifications are idempotent. A save or patch migration preserves stable capability/story identity rather than keying by localized text or scene index. Soft-lock policy is project-specific: the project may require an exit, recovery point, alternate route, or intentionally irreversible commitment. Do not force every hard gate to have a rest site or every ability lesson to be nonlethal. ## Acceptance …

How to install
mdr add jammyfu/open-game-skills/ability-gate@sha256:d0946769b78dff34The line at the top of this page pins the label git:20260913.29703a0, 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.
