Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.
By affaan-m/ECC (GitHub) · coding · 300,508 stars · scanned at commit d2ef268
TypeScript patterns for strict, type-safe, maintainable code in modern TypeScript and JavaScript applications. Covers strict compiler configuration, type design, narrowing, discriminated unions, generics, async and error handling, module boundaries, dependency hygiene, and type-level testing. Use when writing or reviewing TypeScript or JavaScript code.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'typescript-patterns' ] || [ -L ~/.agents/skills/'typescript-patterns' ]; then echo 'A skill folder named typescript-patterns already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/affaan-m/ECC' "$d" && git -C "$d" checkout --quiet 'd2ef2680594f9a17526a6e1a2e18b3d242c5d17b' -- 'pi/core/skills/typescript-patterns' && mkdir -p ~/.agents/skills && cp -R "$d"/'pi/core/skills/typescript-patterns' ~/.agents/skills/'typescript-patterns' && 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/'typescript-patterns' ~/.claude/skills/'typescript-patterns' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
