VibePrompt automates prompt improvement for AI apps. A daily 9:00 AM Codex Automation triggers the vibe-demo-pipeline Skill to run the /demo flow headless: ingest complaints + transcripts, pick the most severe issue, generate 3 GPT-5 prompt variants, score via LLM-as-Judge, write a trace bundle + Summarizer.md, and create synthetic examples in latest.jsonl. Result: measurable iteration, no gut-feel tweaks, zero babysitting.
