# Second Thought

**The anti-hype agent skill. Critique-first, decision-checkpoint engine for AI agents.**

A portable agent skill that challenges every high-commitment decision before execution — catching flaws, surfacing risks, questioning assumptions, and pushing back when an agent is about to confidently accelerate in the wrong direction. Works across Claude Code, Cursor, Codex, Gemini CLI, OpenCode, and GitHub Copilot CLI.
