rust-performance SKILL.md skillA
rust-performance from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/rust-performance@git:20261029.a5b13ddPins git:20261029.a5b13dd in mdr.lock. Pin the fingerprint instead.

Use when writing or reviewing performance-sensitive Rust, reducing allocations, profiling slow code, investigating latency or throughput regressions, or diagnosing binary size and compile time. Covers cost-aware implementation, representative baselines, profiling, measured changes, and regression checks. Triggers include hot path, zero-copy, Criterion, cargo bench, samply, perf, flamegraph, DHAT, cargo-bloat, p99, contention, and performance code review.
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
# Rust Performance Keep cold code readable. For known hot paths, make ownership, allocation, layout, and concurrency costs deliberate. For an optimization claim, reproduce the workload and establish before/after evidence; a plausible rewrite is not a measured improvement. ## Load only the relevant reference or section | Task | Read | |---|---| | Allocation, buffer reuse, cloning, small collections | [Allocation](references/anti-patterns.md#1-allocation) | | Iterator overhead, batching, layout, or hashing | [Iterators](references/anti-patterns.md#2-iterators), [layout](references/anti-patterns.md#3-data-layout), or [hashing](references/anti-patterns.md#4-hashing) | | Async worker stalls, locks, queues, task granularity | [Concurrency](references/anti-patterns.md#5-concurrency) | | Compiler settings, binary/build cost, lint review | [Build configuration](references/anti-patterns.md#6-build-configuration) or [Clippy](references/anti-patterns.md#7-clippy-gates) | | Layout changes, sharding, SIMD, or NUMA | [Optimization patterns](references/optimization-patterns.md) | …

How to install
mdr add lu1sdv/skillsmd/rust-performance@sha256:b0dfd2de98bf1f16The line at the top of this page pins the label git:20261029.a5b13dd, 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.
