Apply when designing types, reviewing a function signature, or writing code in any statically-typed language. Make illegal states unrepresentable, brand semantic primitives, parse external data at boundaries, refuse to lie to the compiler, exhaust variants, derive from authoritative schemas.

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/'principle-type-system-discipline' ] || [ -L ~/.agents/skills/'principle-type-system-discipline' ]; then echo 'A skill folder named principle-type-system-discipline already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/chmonitor/chmonitor' "$d" && git -C "$d" checkout --quiet '04140135acfbd2adb525c7173459b584f9f3bb86' -- '.claude/skills/pstack/upstream/skills/principle-type-system-discipline' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/pstack/upstream/skills/principle-type-system-discipline' ~/.agents/skills/'principle-type-system-discipline' && 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/'principle-type-system-discipline' ~/.claude/skills/'principle-type-system-discipline' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
