Self Improving Applications with Claude Code & Codex

About this video

Build a Self‑Improving Next.js App: Supabase + Vercel Eve + GitHub Issues + Agent Loops Check out Supabase: https://supabase.plug.dev/1wWOTGS The video demonstrates how to build and deploy a self-improving application by scaffolding a Next.js app with Supabase and Vercel’s Eve framework, wiring in the Vercel AI Gateway, and adding a ChatGPT-style UI with ShadCN components. It shows creating a Supabase project, safely adding environment variables, running migrations/tests, and verifying a chat experience with persisted conversations plus a help/feedback agent. The workflow then connects the feedback agent to a GitHub repo so user suggestions and bug reports automatically create GitHub issues using a scoped personal access token. After deploying to Vercel, the script shows using Codex scheduled tasks with GitHub, Supabase, and Vercel connectors to review open issues, validate them against code and logs, open pull requests, and apply improvements (including example prompts and a surfaced security warning), illustrating how agent loops can shorten the development lifecycle. 00:00 Self Improving Apps 01:08 Tools and Setup 03:49 Scaffold Eve and Supabase 05:19 Build Chat UI 06:50 Configure Supabase Keys 08:42 Run Migrations and Test 10:52 Push Repo to GitHub 11:42 Feedback to GitHub Issues 16:22 Deploy on Vercel 17:24 Supabase Data and Storage 19:20 Scheduled Issue Fix Loop 25:21 Review Merge and Wrap Up
