Question 1

What is PRD (Product Requirements Document)?

Accepted Answer

A document that outlines the purpose, features, functionality, and behavior of a product. In the context of vibe coding, a well-structured PRD serves as the primary input for AI coding tools, guiding the generation of functional prototypes.

Question 2

What is Vibe Coding?

Accepted Answer

A term coined by Andrej Karpathy describing a development approach where you communicate your intent through natural language prompts and let AI tools handle the code implementation. The developer guides the direction while the AI handles the details.

Question 3

What is Prototype-as-Code?

Accepted Answer

A working prototype built with actual code (as opposed to static mockups or clickable wireframes). AI coding tools enable PMs to create functional, deployable prototypes that run real logic and connect to real backends.

Question 4

What is Agentic Workflow?

Accepted Answer

An AI-assisted development approach where an AI agent autonomously plans, writes, tests, and iterates on code with minimal human intervention. Tools like Devin, Claude Code, and Replit Agent use agentic workflows to complete complex multi-step tasks.

Question 5

What is Acceptance Criteria?

Accepted Answer

Specific, testable conditions that a feature must meet to be considered complete. In AI-assisted development, clear acceptance criteria are essential for guiding the AI to produce the correct behavior and for validating the output.

Question 6

What is User Story?

Accepted Answer

A short description of a feature from the end user perspective, typically formatted as: As a [role], I want to [action] so that [benefit]. User stories help AI tools understand the intent and context behind feature requests.

Question 7

What is Prompt Engineering?

Accepted Answer

The practice of crafting effective inputs for AI systems to produce desired outputs. For PMs using AI coding tools, prompt engineering involves structuring your requirements clearly with context, specifics, and success criteria.

Question 8

What is AI Code Completion?

Accepted Answer

An AI feature that suggests the next lines of code as you type, based on the surrounding context. Tools like GitHub Copilot, Codeium, and Tabnine provide real-time code completions that speed up development.

Question 9

What is App Builder?

Accepted Answer

An AI tool that generates complete, deployable web applications from natural language descriptions. Examples include Lovable, Bolt.new, and Replit Agent. App builders handle the full stack: frontend, backend, database, and deployment.

Question 10

What is AI IDE?

Accepted Answer

An Integrated Development Environment enhanced with AI capabilities for code generation, editing, and understanding. Cursor and Windsurf are AI-native IDEs that provide deeper AI integration than traditional editors with AI plugins.

Question 11

What is Multi-File Editing?

Accepted Answer

An AI capability where the tool can make coordinated changes across multiple files in a project simultaneously. This is essential for implementing features that touch multiple components, routes, or modules.

Question 12

What is Context Window?

Accepted Answer

The amount of text (measured in tokens) an AI model can process in a single interaction. A larger context window means the AI can understand more of your codebase or PRD at once, leading to more coherent and contextually aware output.

Question 13

What is RAG (Retrieval-Augmented Generation)?

Accepted Answer

A technique where AI systems retrieve relevant information from a knowledge base before generating responses. In coding tools, this allows AI to reference documentation, codebases, and best practices when generating code.

Question 14

What is Codebase Indexing?

Accepted Answer

The process by which AI coding tools analyze and create a searchable index of your entire project. This allows the AI to understand your code structure, conventions, and patterns, resulting in more contextually appropriate suggestions.

Question 15

What is MVP (Minimum Viable Product)?

Accepted Answer

The simplest version of a product that delivers core value to users. AI coding tools have dramatically reduced the effort needed to build MVPs, enabling PMs to create functional prototypes in hours rather than weeks.

Question 16

What is Zero-Shot Prompting?

Accepted Answer

Asking an AI to perform a task without providing examples. For example, describing a feature and expecting the AI to implement it correctly based solely on the description. Works best for simple, well-known patterns.

Question 17

What is Few-Shot Prompting?

Accepted Answer

Providing the AI with a few examples before asking it to perform a similar task. In vibe coding, this might mean showing the AI one component code before asking it to create a similar component with different content.

Question 18

What is Supabase?

Accepted Answer

An open-source backend-as-a-service platform providing a PostgreSQL database, authentication, file storage, and real-time subscriptions. Supabase is the most common backend used by AI app builders like Lovable and Bolt.new.

Question 19

What is Deployment?

Accepted Answer

The process of making your application accessible on the internet. AI builders like Lovable and Bolt offer one-click deployment, while tools like v0 deploy to Vercel. Deployment is the final step in turning a PRD into a sharable prototype.

Question 20

What is Iteration?

Accepted Answer

The process of refining your AI-generated prototype through successive rounds of prompting and feedback. Effective vibe coding typically requires 3-10 iterations to go from initial generation to a polished prototype.
