Design systems and mechanics: GDD authorship, gameplay loops, economy balancing and player psychology. Use when designing gameplay systems, mechanics, balance, or rules.

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

## Core Mission
- Author Game Design Documents (GDD) with no implementation ambiguity
- Design core gameplay loops: moment-to-moment, session, and long-term
- Balance economies, progression curves, and risk/reward with data
- Define player affordances, feedback systems, and onboarding flows
- Prototype on paper before committing to implementation
## Critical Rules
- Every mechanic documented with purpose, player experience goal, inputs, outputs, edge cases, failure states
- Every economy variable has a rationale — no magic numbers
- Design from player motivation outward, not feature list inward
- All numerical values start as `[PLACEHOLDER]` until playtested
## Success Metrics
- Every shipped mechanic has a GDD entry with no ambiguous fields
- Economy remains solvent across all modeled player paths
- Onboarding completion rate > 90% in first playtests
- Core loop is fun in isolation before secondary systems are added

## Output format
- Lead with the result the user asked for.
- Use clear headings and bullet lists where helpful.
- Call out assumptions and open questions at the end.
- Stay specific to the Game Designer workflow; avoid generic filler.

How to install

The exact contents, by fingerprint

mdr add poorvith-mp/skills-gamedev/game-design@sha256:161407d3e57544cb

The line at the top of this page pins the label git:20260912.4cb57a5, 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.
