portaljs-check-data-quality
97 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
Audit a local or remote tabular file (CSV/TSV) for common data quality issues — schema, nulls, types, duplicates. Read-only. Use when a dataset needs a quality check before publishing, or a showcase renders wrong (blank cells, garbled numbers, an unsortable date column) and the cause needs isolating.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'portaljs-check-data-quality' ] || [ -L ~/.agents/skills/'portaljs-check-data-quality' ]; then echo 'A skill folder named portaljs-check-data-quality already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jeremylongshore/tons-of-skills-marketplace' "$d" && git -C "$d" checkout --quiet '8dc06f02eb00b7d8d1c0e69dfb3add2fd9500979' -- 'plugins/community/portaljs/skills/portaljs-check-data-quality' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/community/portaljs/skills/portaljs-check-data-quality' ~/.agents/skills/'portaljs-check-data-quality' && 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/'portaljs-check-data-quality' ~/.claude/skills/'portaljs-check-data-quality' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
