Show GN: set-prompt git레포 기반 프롬프트 저장소 AI에이전트 연결

As developers adopt multiple AI agents, managing fragmented prompts across different tools becomes a significant maintenance burden. set-prompt solves this by centralizing prompt management in a git repository and syncing them via symbolic links, effectively implementing a 'prompt-as-code' workflow. This tool highlights the increasing importance of configuration consistency in the era of diverse AI-assisted development environments.
