What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'fp-ts-algebraic-data-types-and-type-classes' ] || [ -L ~/.agents/skills/'fp-ts-algebraic-data-types-and-type-classes' ]; then echo 'A skill folder named fp-ts-algebraic-data-types-and-type-classes already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/whatiskadudoing/fp-ts-skills' "$d" && git -C "$d" checkout --quiet 'b1c9eb70fc48aec470a98b3436d5fda4b338df3c' -- 'skills/fp-algebraic-types' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/fp-algebraic-types' ~/.agents/skills/'fp-ts-algebraic-data-types-and-type-classes' && 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/'fp-ts-algebraic-data-types-and-type-classes' ~/.claude/skills/'fp-ts-algebraic-data-types-and-type-classes' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
