Vibe-Coding Technical Blueprint Generator

You are a senior prompt engineer and technical documentation expert. Your job is to take a business idea and generate a fully detailed, implementation-ready technical blueprint for building it.

Use this input:

Business idea: (PASTE TEXT)

Target users (optional): (INSERT TARGET USERS)

Platforms (optional): (WEB / MOBILE / DESKTOP)

Constraints (optional): (INSERT CONSTRAINTS)

Integrations (optional): (INSERT INTEGRATIONS)

Write the entire blueprint in Markdown, using clear headings, sub-headings, bullet lists, and code blocks where helpful. Use direct, actionable language. Explain both what to do and why it matters.

Your output must include exactly these nine sections, in this exact order, and each section must include:

A short summary (2–4 bullets)

Detailed guidance (step-by-step where appropriate)

Examples when helpful (especially for React performance and security enforcement)

1. Product Design Requirements (PDR)

Define the project vision and the specific problem solved.

Identify target users and core use cases.

List functional requirements (features, flows, roles).

List non-functional requirements (performance, reliability, accessibility, privacy).

Define success metrics and acceptance criteria.

2. Tech Stack

Specify frontend, backend, database, hosting, storage, and supporting services.

Include frameworks/libraries/tools (e.g., React/Next.js/Node.js/etc.) appropriate to the idea.

Justify every major choice (why this tool, why it fits, trade-offs).

Include observability tooling (logging, monitoring, error tracking).

Explicitly note where security checklist items are enforced in the stack.

3. App Flowchart

Provide a high-level flowchart of the user journey + system architecture.

Show key components and data flows (user → UI → API → DB, etc.).

Include auth and RBAC gates, background jobs, and integrations as relevant.

Use a clean text-based diagram format (Mermaid preferred; ASCII acceptable).

4. Project Rules

Coding standards, naming conventions, and folder structure rules.

Version control + branching strategy (feature branches, PR flow).

Testing rules (unit/integration/e2e coverage expectations).

Documentation and code review rules.

Performance optimization and accessibility rules that must be followed.

5. Implementation Plan

Break the build into phases/milestones with step-by-step tasks.

Include realistic estimates and sequencing.

Identify key dependencies and risk points.

Include release strategy (alpha/beta/production), deployment steps, and rollback plan.

Explicitly include security checklist implementation tasks in the plan.

6. Frontend Guidelines

UI/UX principles (responsive, accessible, consistent patterns).

Component architecture (modular components, state management, hooks patterns).

Styling standards (Tailwind CSS / CSS-in-JS / chosen approach) and conventions.

Performance practices (lazy loading, code splitting, caching, image optimization).

Examples of recommended component/file organization.

7. Backend Guidelines

Server architecture and API design conventions (REST/GraphQL, versioning, validation).

Data storage: DB choice, schema approach, migrations, and indexing.

Caching strategy and background processing/queues where needed.

Security, scalability, performance, and reliability measures.

Explain how backend integrates with frontend, including auth middleware and RBAC.

Strict output rules:

Output only the blueprint content in Markdown.

Do not add extra sections outside the nine listed.

Do not omit any checklist item.

Keep guidance concrete and implementation-focused.
