arm-sve from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when writing or porting AArch64 SIMD to SVE or SVE2: arm_sve.h intrinsics, predicates, vector-length-agnostic loops, auto-vectorization, or SVE registers in GDB. Not for NEON: use simd-intrinsics.
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
# Arm SVE and SVE2 ## Contract | Field | Bound contract | |---|---| | Trigger | AArch64 code needs vector-length-agnostic SIMD: a NEON loop is being ported, an `arm_sve.h` kernel is being written, auto-vectorization to SVE is being checked, or SVE register state is being inspected in GDB. | | Authority | Reversible local: writes only the source files the user names; rollback is reverting them in version control. No remote mutation. | | Side effect | New or edited C sources. Runs the binary on the host or under QEMU for verification. | | Done | The kernel compiles with `-march=armv9-a+sve2`, produces the same result as the scalar reference for lengths that are not a multiple of the vector length, and runs correctly at two different vector lengths (hardware and QEMU, or two QEMU `sve<N>` settings). | ## Inputs - Source loop or NEON kernel to port, with a scalar reference to compare against. - Target machines and their SVE level: Graviton3 (Neoverse V1) has SVE, Graviton4 (Neoverse V2) has SVE2, Apple M1 through M3 have NEON only, Apple M4 has SME with streaming SVE and no non-streaming SVE. - Compiler: GCC or Clang, and version (`gcc --version`, `clang --version`). …

How to install
mdr add outlinedriven/outline-driven-development/arm-sve@sha256:0561ac599c220186The 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.
