cinderx-isa-microarch-compare

cinderx-isa-microarch-compare is a skill for Claude Code from sisibeloved/cpython-optimize-skill. It costs 56 tokens per session (335 once invoked), scanned A, original, MIT.

A comparison of processor instruction sets and chip designs, such as Kunpeng Arm processors and x86 processors, to explain why the same CinderX code performs differently.

In plain words
What is it for?
Use it to build a platform comparison, connect affected benchmarks to hardware or generated-instruction differences, identify candidate optimizations, and define the smallest verification command.
Why use it?
It tests whether a platform difference is real before focusing on one compiler stage. It accounts for instructions, caches, branch prediction, memory behavior, system settings, and generated code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cinderx-isa-microarch-compare scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

CinderX ISA/Microarch Compare

平台差异分析先建立矩阵,再进入 HIR/LIR 细节。

矩阵

  • 平台:Kunpeng、x86、内核、容器、CPU governor。
  • ISA:指令选择、SIMD、原子、barrier、寄存器和调用约定。
  • 微架构:cache、分支预测、流水线、内存带宽、TLB、hugepages。
  • 观测:perf top/stat、机器码、speedup、benchmark 覆盖。
  • lowering:CinderX codegen 是否生成不同形态。

反问 Gate

  • 平台对、CPU 型号、benchmark 集合或性能口径无法唯一确定时,询问用户。
  • perf/硬件计数器/CPU governor/hugepages 需要权限或会改变环境时,询问。
  • 系统性扫描范围超过当前预算时,询问先做 L0/L2 子集还是进入 L3/L4。

输出

平台差异点、受影响 benchmark、候选优化点、最小验证命令和需要排除的环境漂移。

不要一开始就陷入某个 HIR pass;先证明平台差异存在。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cinderx-isa-microarch-compare is a skill published in the GitHub repository sisibeloved/cpython-optimize-skill (2 stars, last pushed 9d ago), licensed MIT. It adds 56 tokens to every session and 335 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
