cpu-cache-opt SKILL.md skillA
cpu-cache-opt from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/cpu-cache-opt@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when diagnosing cache misses with perf, fixing false sharing, choosing AoS or SoA layout, or adding software prefetch. Not for cache theory: use memory-hierarchy-and-caches.
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
# CPU cache optimization Cache performance is a layout property before it is a code property. Measure with hardware counters, move the data so the working set fits, and re-measure. Every change must show up in the counters, or it reverts. ## Contract | Field | Bound contract | |---|---| | Trigger | The task diagnoses cache misses, detects or fixes false sharing, restructures data layout, evaluates AoS versus SoA, or decides on software prefetch. | | Authority | Read-only. The skill runs performance tools that read the program and prints guidance; source and build changes land through the normal coding path. No remote mutation. | | Side effect | None beyond tool output files that the profiling tools write to their own scratch locations. | | Done | A measured before and after for the proposed layout change exists, with the cache counters quoted, or the diagnosis names the miss class and the evidence for it. | ## Inputs - The program and a reproducible workload: required. A benchmark that runs the hot loop long enough to fill counters. - The build: required, with symbols for attribution and without changing optimization between measurements. …

How to install
mdr add outlinedriven/outline-driven-development/cpu-cache-opt@sha256:6212fc7def7edb06The line at the top of this page pins the label git:20260905.fd53e99, 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.
