Turn a game-design question into one falsifiable theory packet instead of a framework collage. Use when a designer must explain why a mechanic may create a player experience, analyze mechanics-dynamics-aesthetics, test a core loop, inspect choice, uncertainty, progression, resource flow, mastery, autonomy, competence, or relatedness, compare design variants, or turn conflicting playtest interpretations into a bounded prototype. Choose one primary lens, state its limits, separate observation…
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 Design Theory Use theory as a lens that makes a design claim testable. Do not use it as a substitute for player evidence, a universal recipe for fun, or a reason to turn one taxonomy into permanent player labels. ## When to use this skill Use it to: - trace a mechanic through runtime behavior to a desired player experience; - explain a weak, confusing, dominant, shallow, or conflicting game system; - choose between two design variants before full implementation; - analyze a core loop, progression, reward, resource, uncertainty, or mastery structure; - frame motivation as a hypothesis about autonomy, competence, or relatedness; - reconcile playtest observations that support different explanations; - define the smallest prototype that could disprove a design belief. Do not use it to write a full GDD, run production, tune moment-to-moment feedback, design a HUD, or implement an engine system. Route those to `bmad-gds`, `game-studio-harness`, `game-feel`, `game-ui-ux`, or the narrowest engine skill. ## Instructions ### 1. Freeze one design question Write the decision in a form that can change: - What player behavior or experience is observed? …

How to install
mdr add akillness/jeo-skills/game-design-theory@sha256:5ccf37805ded03a0The line at the top of this page pins the label v1.0, 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.
