Use when multiple local players share one game instance and the project needs stable player/device ownership, join/leave rules, camera policy and shared-state boundaries.

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

# Local co-op

Ask the presentation/control model: shared-camera, split-screen, take-turns, hybrid, or existing.

## Contract

Publish:
- stable `coop_session_id` and revision
- stable `player_id` and bound `device_id`
- join/leave request identity and eligibility
- camera/view policy per local player set
- shared versus per-player inventory/progression/input context
- respawn/reconnect behavior

## Ownership

This skill owns local player membership and device-to-player binding. `input-design` owns semantic actions, camera skills own camera behavior, inventory/progression own canonical state, and `performance-budget` owns presentation budgets.

## Rules

1. Join/leave/rebind requests are idempotent and cannot create duplicate players or leave one device controlling two unintended actors.
2. Shared-camera, split-screen and take-turns are project policies; presentation degradation strategy is owned by performance budgets, not hardcoded here.
3. Mid-session join may use onboarding, spectating or immediate control according to project policy; no universal re-tutorial rule.
4. Device disconnect preserves player identity long enough for the declared reconnect/fallback policy.

How to install

The exact contents, by fingerprint
mdr add jammyfu/open-game-skills/local-coop@sha256:5dc24485a1062ed3

The line at the top of this page pins the label git:20260913.e4d1fcc, 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.
