Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Modern TypeScript 5.x idioms — strict tsconfig (strict, noUncheckedIndexedAccess), the type system (unions/intersections, generics + constraints, narrowing, discriminated unions, unknown vs any, utility types, satisfies, as const, template-literal types), ESM & moduleResolution, and type-safe patterns (branded types, exhaustiveness). Use when configuring a tsconfig, writing or reviewing type-safe TypeScript, designing generics or a discriminated union, or decoding a tsc error.

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/'modern-typescript' ] || [ -L ~/.agents/skills/'modern-typescript' ]; then echo 'A skill folder named modern-typescript already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/stanfish06/skillquarium' "$d" && git -C "$d" checkout --quiet 'f748ea91aa51ce8fc42c27c809dba73a8377b1d5' -- 'skills/modern-typescript' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/modern-typescript' ~/.agents/skills/'modern-typescript' && 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/'modern-typescript' ~/.claude/skills/'modern-typescript' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
