Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install simd-vectorization-intrinsics

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent reads auto-vectorisation reports from -fopt-info-vec, explains why vectorisation failed and writes SSE2, AVX2 or NEON intrinsics. It also helps detect available instruction sets at runtime.
