Claude Skill Auto-Generates Full App Codebases

Someone built a Claude skill that takes any app idea and auto-generates the entire codebase without asking a single question.

The trick is front-loading everything into the initial prompt - requirements analysis, tech stack selection, phased build plan (14-18 phases), git commit messages, and E2E testing strategy. Claude then silently executes each phase back-to-back.

Key sections in the skill.md:

1. Requirements extraction (pulls implicit features like auth, admin panels)
2. Stack selection with justification (Next.js + TypeScript + Tailwind typical)
3. Detailed phase plan with specific deliverables
4. Auto-execution mode (no mid-build questions)
5. Git commits after each phase
6. Playwright E2E tests throughout

Drop it in ~/.claude/skills/fullstack-builder.md and just describe your app. Claude handles the rest - database schemas, API routes, frontend components, deployment configs. Pretty wild for rapid prototyping when you need a working demo fast.

Turns hours of scaffolding into one prompt.
