End-to-end Snowflake query optimization — fetch, rewrite, prove parity, benchmark, report. Use when: (1) User wants an **end-to-end flow** (fetch + rewrite + parity + benchmark + report), not just a rewrite (2) Input is a `.sql` file path in the repo (optionally `:L10-L80` line range), OR a Snowflake `query_id` (UUID) (3) User expects a correctness proof (row-count + per-column signature + multiplicity) before accepting the rewrite (4) Task says "optimize this query end-to-end", "tune this file…

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/'snowflake-query-optimization' ] || [ -L ~/.agents/skills/'snowflake-query-optimization' ]; then echo 'A skill folder named snowflake-query-optimization already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/AltimateAI/data-engineering-skills' "$d" && git -C "$d" checkout --quiet 'd6a2faa14b32da613366856b44811138b8e26127' -- 'skills/snowflake/snowflake-query-optimization' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/snowflake/snowflake-query-optimization' ~/.agents/skills/'snowflake-query-optimization' && 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/'snowflake-query-optimization' ~/.claude/skills/'snowflake-query-optimization' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
