Asm analysis

Skill DiamonDinoia/simdref/skills/asm-analysis

Use when the user asks to look at, analyse, profile, or optimise ASSEMBLY or the runtime performance of compiled C/C++ — from a source file, CMake/Makefile target, object file, binary, or raw .s listing. TRIGGER on: "look at the asm", "inspect codegen", "why is this loop slow", "can this be vectorised", "what intrinsic replaces this", "annotate this .s", and on any "make this faster / vectorise / tune / maximise throughput" request for C/C++, including hardware-specific ones ("faster on Zen4", "tune for Skylake-X", "use AVX-512", "avoid the port-5 bottleneck"). Default here whenever the goal is runtime performance of compiled C/C++, unless scoped to source-only (readability, algorithmic complexity, API ergonomics). DO NOT TRIGGER for pure source refactoring, style, or C++ semantics questions that don't require reading generated code.From its SKILL.md

5 stars5 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

asm-analysis

Entrypoint for the shared simdref assembly analysis workflow.

Before doing any assembly analysis, read and follow references/workflow.md. Treat that file as the source of truth for the compile → objdump/-S → simdref annotate → simdref llm batch → proposal pipeline.

Claude Code install and updates

This skill lives at skills/asm-analysis/SKILL.md inside the simdref source tree, which is also published as a Claude Code plugin marketplace. Preferred install at the Claude Code prompt:

/plugin marketplace add DiamonDinoia/simdref
/plugin install asm-analysis@simdref

To refresh later:

/plugin marketplace update simdref
/plugin install asm-analysis@simdref

Manual alternatives, either symlink from a checkout for always-current updates or install a one-off snapshot:

git clone https://github.com/DiamonDinoia/simdref.git ~/src/simdref
mkdir -p ~/.claude/skills
ln -sf ~/src/simdref/skills/asm-analysis ~/.claude/skills/asm-analysis
# later: (cd ~/src/simdref && git pull)  # updates skill in place

# or snapshot:
mkdir -p ~/.claude/skills/asm-analysis && \
  curl -fsSL https://raw.githubusercontent.com/DiamonDinoia/simdref/main/skills/asm-analysis/SKILL.md \
  -o ~/.claude/skills/asm-analysis/SKILL.md

If the user has an older PyPI-shipped copy, point them at the packaged location for the upgrade diff:

pip show -f simdref | grep SKILL.md
