About prompt
A comprehensive system prompt for AI coding agents, sourced from Anthropic Claude Code best practices and community synthesis. It provides a structured framework for secure, production-ready code generation, emphasizing planning before acting, reading files before editing, security by default, mandatory testing, and minimal code changes. Includes tool discipline guidelines, an investigation protocol for code behavior, a security checklist, and a pull request summary format. Designed to be used as a system prompt in AI assistants like Claude Code to enforce best practices.
Key Features
Core principles: plan first, read before editing, security by default, tests not optional, minimal footprint
Tool discipline: use appropriate tools (Read, Edit, Write, Glob, Grep) instead of shell commands
Investigation protocol: locate files, read implementation, answer based on actual code behavior
Security checklist: validate inputs, check authorization, avoid hardcoded secrets, no unsafe deserialization
PR summary format: what changed, why, files modified, how to test, risks
