AI Commonsense Reasoning

Q: What is a Claude Code skill and how does the AI Commonsense Reasoning skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. AI Commonsense Reasoning is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.

USE FOR: Commonsense reasoning for AI systems — world knowledge, naive physics, folk psychology, temporal/spatial reasoning, default reasoning, and their formalization. Use for reasoning about everyday knowledge that humans take for granted but AI systems need explicitly, especially when a downstream project must make implicit context explicit. DO NOT USE FOR: formal KR/ontology engineering (use @ai-symbolic-neuro); causal/deontic reasoning (use @ai-causal-deontic); formalisation in Lean (use @lean-knowledge-formalization). TRIGGERS: commonsense, naive physics, folk psychology, temporal reasoning, spatial reasoning, default reasoning.

Formalizing the vast body of everyday knowledge that underlies human reasoning and is critical for AI systems operating in real-world contexts.

What this skill does

AI Commonsense Reasoning is a community-contributed Claude Code skill in the physics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ai-commonsense-reasoning/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The AI Commonsense Reasoning Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 93,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
