Show HN: Think Better – AI 비서를 위한 155가지 의사결정 과학 규칙

Your AI writes code fast but makes terrible decisions. Think Better injects structured decision frameworks directly into your AI prompts. Website · Documentation · Quick Reference · Contributing Works with Claude · GitHub Copilot · Antigravity You ask your AI "Should we migrate to microservices?" and get a generic pros/cons list. No framework. No bias detection. No structured analysis. Just vibes. Think Better fixes this. It gives your AI access to 10 decision frameworks, 15 decomposition methods, 12 cognitive bias detectors, and 160 knowledge records — turning surface-level responses into structured, rigorous analysis. # macOS / Linux curl -sSL https://raw.githubusercontent.com/HoangTheQuyen/think-better/main/install.sh | bash # Windows (PowerShell) irm https://raw.githubusercontent.com/HoangTheQuyen/think-better/main/install.ps1 | iex Then install skills for your AI: think-better init --ai claude # Claude Code think-better init --ai copilot # GitHub Copilot think-better init --ai antigravity # Antigravity Other install methods: go install github.com/HoangTheQuyen/think-better/cmd/make-decision@latest or clone &make build Just talk to your AI naturally. Think Better auto-activates when it detects a decision or problem: You: "Should we migrate from React to Next.js for our main app?"
