Catalog of informal fallacies with definitions, canonical examples, and detection heuristics. Covers relevance fallacies (ad hominem, straw man, red herring, appeal to authority, appeal to emotion), presumption fallacies (false dichotomy, complex question, begging the question), ambiguity fallacies (equivocation, amphiboly, accent), causal fallacies (post hoc, slippery slope, correlation-causation), and statistical fallacies (hasty generalization, cherry-picking).

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/'informal-fallacies' ] || [ -L ~/.agents/skills/'informal-fallacies' ]; then echo 'A skill folder named informal-fallacies 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 "$d" checkout --quiet 'e179dfe911f3b3c2ff8bcd90ecd6ee4738648d17' -- 'examples/skills/logic/informal-fallacies' && mkdir -p ~/.agents/skills && cp -R "$d"/'examples/skills/logic/informal-fallacies' ~/.agents/skills/'informal-fallacies' && 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/'informal-fallacies' ~/.claude/skills/'informal-fallacies' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
