Fine to try.

Use when the user has a messy tabular data dump (CSV/TSV/parquet/Excel/JSON) and wants it iteratively cleaned to an inferred data contract — a checklist of deterministic pass/fail checks, not a quality score. A single agent profiles the table, synthesizes a per-column contract compiled into binary checks (types, nulls, duplicates, inconsistent categories, format/range violations, outliers), then applies one targeted transform at a time, keeping it only if it reduces its target check's violation…

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/'tabular-cleanup' ] || [ -L ~/.agents/skills/'tabular-cleanup' ]; then echo 'A skill folder named tabular-cleanup already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gaasher/Agent-Loop-Skills' "$d" && git -C "$d" checkout --quiet 'f1169e6db0b0f8a83ced3a18562b7c57e14a748a' -- 'loops/tabular-cleanup' && mkdir -p ~/.agents/skills && cp -R "$d"/'loops/tabular-cleanup' ~/.agents/skills/'tabular-cleanup' && 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/'tabular-cleanup' ~/.claude/skills/'tabular-cleanup' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
