strong-types

77 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

By jpcaparas/skills (GitHub) · coding · 57 stars · scanned at commit c95f32e

Passive skill enforcing strong typing when writing or reviewing PHP, TypeScript, Python, C#, Kotlin, Go, Rust, or other typed code. Bans any/mixed, untyped signatures, blind ??/|| fallback chains; prefers DTOs, enums, generics, strict flags. Do NOT force typing onto untyped languages.

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/'strong-types' ] || [ -L ~/.agents/skills/'strong-types' ]; then echo 'A skill folder named strong-types already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jpcaparas/skills' "$d" && git -C "$d" checkout --quiet 'c95f32eca37fdd414431c43ee102e7738f341b74' -- 'skills/engineering/strong-types' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/engineering/strong-types' ~/.agents/skills/'strong-types' && 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/'strong-types' ~/.claude/skills/'strong-types' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
