performance-patterns SKILL.md skillA
performance-patterns from intel/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add intel/skills/performance-patterns@git:20260903.b1ad034Pins git:20260903.b1ad034 in mdr.lock. Pin the fingerprint instead.

Detect and fix x86/C/C++ performance patterns from source code or profiling output (perf, VTune, flamegraphs). Invoke when the user asks to optimize, review for performance, or write new SIMD/vectorized code — even without profiling data. Trigger on: serial accumulator loops, narrow SIMD (xmm/ymm that could be ymm/zmm), _mm* intrinsics, HITM/cmpxchg clusters, false sharing, missing restrict or vzeroupper, futex_wake/notify_all thundering herd, hot symbol inside a system library (.so) with a…
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
<!-- (C) 2026 Intel Corporation, MIT license --> # Performance patterns skill A growing catalog of well-known code patterns that cause performance problems, with detection signals and resolution playbooks for each. --- ## How to use this skill ### Step 1 — Load the right file for your context | Context | Read this file | |---------|---------------| | You have **profiling output** (perf annotate, perf c2c, perf stat, VTune, flamegraph, etc.) | `triggers/from-profile.md` | | You are **reading existing source code** and have no profiling data yet | `triggers/from-source.md` | | You are **writing new** performance-sensitive C/C++ or SIMD code | `guidelines/new-code.md` | The trigger files cover all the same patterns; they are separated so you only load what is relevant. `guidelines/new-code.md` is a write-time checklist — load it instead of a trigger file when generating new code, not reviewing it. ### Step 2 — Identify the matching pattern Each trigger file contains a compact table and brief descriptions — enough to decide whether the code or profile matches a known pattern. ### Step 3 — Read the pattern detail file …

How to install
mdr add intel/skills/performance-patterns@sha256:dd41a91f1f610292The line at the top of this page pins the label git:20260903.b1ad034, 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.
