raghurammrsd/OneAtlas_App_compiler — reverse-engineered prompt

Build me a Python FastAPI app called OneAtlas AppSpec Compiler. I want to type a plain English product idea, then have the system turn it into a clean application spec through clear stages, intent, data schema, app design, validation, repair, and runtime verification. It should not just return a random AI answer. It should check that entities, roles, workflows, APIs, pages, integrations, tenant isolation, and relationships make sense, then try to repair problems and log what it changed.

Please include API routes to start a generation job, stream progress for that job, fetch the final output, run a manual repair, list supported integrations, and view evaluation results. Support AI provider routing with Groq, Gemini, OpenAI and OpenRouter style fallback, with retries, latency and cost tracking where possible. Include a small integration registry for Slack, WhatsApp, Gmail, Stripe, webhooks and common tools. Add tests, sample evaluation prompts, local setup, and a simple way to run it locally. Look up current docs online if needed.
