Overview
Why
AI agents fail more from vague prompts than from weak models. Developers ship Cursor-or-Claude-Code requests like "build me an auth flow" and watch the agent hallucinate scope. VibingCoderAI is a strict translator — vague ideas in, structurally complete senior-engineer-grade briefs out.
How
A master system prompt enforces structural completeness — accessibility requirements, explicit error-handling, out-of-scope boundaries. The brief is copy-pasteable Markdown that Claude Code, Cursor, GitHub Copilot, or Windsurf can execute without re-interpretation. Next.js 16 App Router frontend on Vercel calls an AWS Lambda backend over public HTTPS; the Lambda runs the Anthropic Claude API behind Terraform-provisioned API Gateway + DynamoDB.
Trade-offs
The master prompt is opinionated — it forces structure that some developers find overkill for prototypes. Accepted: the target user is a senior engineer wanting prompt rigour, not a hobbyist seeking conversational flexibility. Lambda over HTTPS rather than direct browser-to-Claude was the more boring choice — and the right one for adding auth + billing later.
