game-math-and-simulation SKILL.md skillA
game-math-and-simulation from peterbamuhigire/chwezi-dev-engine is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add peterbamuhigire/chwezi-dev-engine/game-math-and-simulation@git:20260911.7afa6eaPins git:20260911.7afa6ea in mdr.lock. Pin the fingerprint instead.

Use when a game system needs explicit vector, matrix, quaternion, geometry, interpolation, collision, camera, steering, probability, or numerical-simulation rules; use gameplay-systems-architecture for ownership and the engine skill for API integration.
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 Math and Simulation Turn mathematical intent into named coordinate spaces, explicit units, stable numerical methods, deterministic oracles, and player-visible behaviour that survives variable frame time. ## Prerequisites Load the approved mechanic or rendering requirement, `gameplay-systems-architecture`, and the selected engine skill before choosing engine-specific types or APIs. <!-- dual-compat-start --> ## Use When - Specifying movement, aiming, cameras, animation blending, steering, trajectories, collision, procedural placement, spatial queries, simulation, or shader mathematics. - Debugging jitter, drift, tunnelling, gimbal-like rotation defects, unstable springs, frame-rate dependence, or incorrect coordinate conversions. - Writing deterministic mathematical test oracles for gameplay, tools, or rendering. ## Do Not Use When - The task is system ownership, persistence, or event architecture without a mathematical defect; use `gameplay-systems-architecture`. - The task is render-pipeline, material, or GPU design; use `real-time-game-graphics` and return here for the mathematical contract. …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/game-math-and-simulation@sha256:adf9667e7ecf869aThe line at the top of this page pins the label git:20260911.7afa6ea, 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.
