I vibe-coded an internal tool that slashed my content workflow by 4 hours

One of the biggest challenges I face as a content expert is repurposing my written blogs for social media. Before now, I had to ask AI for summaries or try to get them myself. I became very busy recently, and I don't have time for that anymore. The best solution for me was building a tool that helps me generate social media content from my blog and posts on my behalf. I was in a meeting of content professionals recently. A key point that was hammered on regarding the use of AI in content creation is the need to maintain a strict Human-in-the-Loop (HITL) workflow. This resonated well with me. I had initially planned to build an agent to automate and schedule social media posts. This, however, leaves out the HITL factor, so I restrategized. Here is the technical breakdown of how I built an Agentic Content Engine using Next.js 15, Gemini 3.1 Pro, and Discord Webhooks.
