apple-silicon SKILL.md skillA
apple-silicon 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/apple-silicon@git:20260912.5c5b759Pins git:20260912.5c5b759 in mdr.lock. Pin the fingerprint instead.

Use when tuning or profiling native code on Apple M-series Macs: unified memory, 16 KiB pages, Accelerate and Metal for matrix work, xctrace and leaks, Rosetta 2, or sysctl hardware queries.
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
# Apple Silicon ## Contract | Field | Bound contract | |---|---| | Trigger | Code runs on an M-series Mac and needs to be checked for page-size assumptions, moved onto Accelerate or Metal for matrix work, profiled with Instruments or the command-line memory tools, or diagnosed for Rosetta 2 translation. | | Authority | Read-only: reads the host through `sysctl`, `arch`, `lipo`, `file`, `xctrace`, `vmmap`, `heap`, `leaks`, and `sample`, and writes traces only under the output path the user names; rollback is deleting those trace files. No remote mutation. | | Side effect | Trace and sample files in the named output directory. Profiling attaches to the target process. | | Done | The report names the chip and its features from `sysctl`, states whether the binary runs native or translated, lists every page-size assumption found in the code with its fix, and points each hotspot at the Accelerate, Metal, or threading change that addresses it. | ## Inputs - The binary or source under review, and how it is launched. - Whether the workload is matrix or convolution heavy (Accelerate and Metal candidates) or general CPU work. - Output directory for traces. …

How to install
mdr add outlinedriven/outline-driven-development/apple-silicon@sha256:936eba320007bb6eThe line at the top of this page pins the label git:20260912.5c5b759, 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.
