Deductive and inductive reasoning, formal and informal logical structure, validity, soundness, and rules of inference. Covers propositional logic, quantified reasoning, syllogisms, common inference patterns (modus ponens, modus tollens, hypothetical syllogism, disjunctive syllogism), and the distinction between deductive certainty and inductive probability. Use when the question is not whether a premise is true but whether the reasoning from premises to conclusion is logically valid.

Works with any agent that supports SKILL.md skills.

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/'logical-reasoning' ] || [ -L ~/.agents/skills/'logical-reasoning' ]; then echo 'A skill folder named logical-reasoning already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Tibsfox/gsd-skill-creator' "$d" && git -C "$d" checkout --quiet 'e179dfe911f3b3c2ff8bcd90ecd6ee4738648d17' -- 'examples/skills/critical-thinking/logical-reasoning' && mkdir -p ~/.agents/skills && cp -R "$d"/'examples/skills/critical-thinking/logical-reasoning' ~/.agents/skills/'logical-reasoning' && 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/'logical-reasoning' ~/.claude/skills/'logical-reasoning' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
