Use before reporting any cosine similarity computed over embeddings or transformer hidden states, whether the agent computed the vectors or loaded them. Measures the anisotropy of each side, centres by the population mean, and scores matched pairs against a permuted floor taken from the same comparison. Use when comparing one model's embeddings across precisions, runtimes or layers, when evaluating retrieval, probes or adapters, or before calling a similarity high, two conditions in agreement, …

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'embedding-anisotropy-check' ] || [ -L ~/.agents/skills/'embedding-anisotropy-check' ]; then echo 'A skill folder named embedding-anisotropy-check already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/github/awesome-copilot' "$d" && git -C "$d" checkout --quiet '227949a7542a55d2155c00e7cdb998d9a0fee4f3' -- 'skills/embedding-anisotropy-check' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/embedding-anisotropy-check' ~/.agents/skills/'embedding-anisotropy-check' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'embedding-anisotropy-check' ~/.claude/skills/'embedding-anisotropy-check' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
