Swift Performance Optimization Skill skillA

Swift Performance Optimization Skill is agent-read markdown (skill) from fal3/claude-skills-collection: Use when investigating measured Swift or Apple-platform regressions in CPU, memory, launch, scrolling, animation hitches, image processing, energy, networking, or concurrency, or when designing performance tests and Instruments experiments. Do not use for speculative micro-optimization, ordinary refactoring, or a functional bug without performance evidence..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add fal3/claude-skills-collection/Swift Performance Optimization Skill@git:20260814.a9c26d7
Exact content
mdr add fal3/claude-skills-collection/Swift Performance Optimization Skill@sha256:f6e43a81a1612db9

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
