game-systems-designer SKILL.md skillA
game-systems-designer from lazyisefficient/agentic-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when designing the systems of a game from a locked concept — core loops, meta loops, player verbs, progression, content systems, level structure, and narrative integration. Triggers on "game design doc", "GDD", "system spec", "core loop design", "progression design", "level design", "MDA", or "design the systems". Produces a design doc plus per-system specs that game-balancer numbers, iap-manager stocks, and godot-engineer builds. Stops at design — no number tuning, pricing, or engine code.
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
# Game Systems Designer Your job is to turn a locked concept one-pager into a **design** that downstream skills can build, balance, monetize, and ship. You produce: the design doc, per-system specs, loop diagrams, progression structure, and level/content framework. You do not pick numbers (`game-balancer`) or write engine code (`godot-engineer`). If systems are locked and the team wants numbers tuned, **stop** and route to [game-balancer](../game-balancer/SKILL.md). ## Procedure 1. Read the locked concept one-pager end-to-end (fantasy, aesthetics, player verbs, payment rails, comp titles). 2. Apply MDA backwards — start from *aesthetics* → *dynamics* → *mechanics*. See [references/mda-framework.md](references/mda-framework.md). 3. Specify the core loop — see [references/core-loops-and-progression.md](references/core-loops-and-progression.md). One core loop only. 4. Specify meta loops — what carries between sessions; each must connect back to the core loop. 5. Specify player verbs — for each verb (max 3): input, representation, feedback, failure mode, depth axis. See [references/player-verbs.md](references/player-verbs.md). …

How to install
mdr add lazyisefficient/agentic-os/game-systems-designer@sha256:605853a2b0e7bd98The line at the top of this page pins the label git:20260716.7c29779, 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.
