optimize-bevy-game SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
optimize-bevy-game from velimirmueller/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add velimirmueller/claude-skills/optimize-bevy-game@git:20261009.762665fPins git:20261009.762665f in mdr.lock. Pin the fingerprint instead.

Use when a Bevy game stutters, drops frames, loads slowly, or ships a large binary or wasm — measure with diagnostics and Tracy/Chrome traces first, then fix change detection, system parallelism, batching, per-frame allocations, and release/wasm profiles.
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
# Optimize Bevy Game Bevy 0.20. Rationale per rule: [optimization-patterns.md](optimization-patterns.md). Versions: [stack-versions](../_shared/stack-versions.md). Principle: [measure before optimizing](../../core/_shared/engineering-principles.md). ## 1. Audit current state (change nothing) ```bash cat .claude/stack-profile.md 2>/dev/null # hosting/web target, task_runner grep -nE '^\[profile|opt-level|lto|codegen-units|strip|panic' Cargo.toml grep -nE 'trace|tracing|dynamic_linking|"debug"' Cargo.toml grep -rnE 'FrameTimeDiagnosticsPlugin|LogDiagnosticsPlugin|FpsOverlay' src/ grep -rnE 'Vec::new\(\)|collect::<Vec|format!\(|\.clone\(\)' src/ | head -20 # per-frame allocation suspects grep -rnE 'iter_mut\(\)|&mut [A-Z]' src/ | head # mutable access that marks change ls -l target/release/* 2>/dev/null | head -3; ls -l dist/*.wasm 2>/dev/null ``` State the symptom as a number before touching code: frame time in ms (not FPS), load time in s, binary or wasm size in MB. "It feels slow" is not a symptom. ## 2. Decide what to do - **No measurement yet** → step 5 (measure). Stop there until the numbers exist. …

How to install
mdr add velimirmueller/claude-skills/optimize-bevy-game@sha256:ef0ac7b54ec67b22The line at the top of this page pins the label git:20261009.762665f, 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.
