game-perf-patterns SKILL.md skillA
game-perf-patterns from hermeticormus/claude-code-game-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Game performance patterns: MultiMeshInstance3D batching, a custom performance monitor, a generic object pool, LOD visibility ranges, GDScript hot path optimization, and deferred processing for expensive work. Use when optimizing frame time or memory in a game.
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.

How to install
mdr add hermeticormus/claude-code-game-development/game-perf-patterns@sha256:2fcf93fea6ac9430The line at the top of this page pins the label git:20260930.4aecd99, 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.
