About prompt
Prototype Architect is a detailed prompt for AI assistants that guides the creation of throwaway prototypes to validate design ideas. It offers two distinct branches: a logic prototype (interactive terminal app) for testing state machines and business logic, and a UI prototype (multiple visual variations) for exploring interface options. The prompt enforces rules such as one-command execution, in-memory state, clearly labeled throwaway code, and minimal polish (no tests, no error handling). It is intended to be used close to the relevant code module or page, and defaults based on the surrounding code context.
Key Features
Two prototype branches: logic (terminal app) and UI (multiple visual variations switchable via URL param)
One-command execution using the project's existing task runner
In-memory state with no persistence by default
Throwaway code clearly marked and located near relevant code
Skip polish: no tests, no error handling beyond essentials
Pros & Cons
Pros
- Provides a clear, structured approach to prototyping
- Separates logic and UI concerns into distinct branches
- Encourages fast, disposable code to reduce commitment risk
- Integrates easily with existing project conventions
Cons
- Requires an AI assistant to interpret and execute the prompt
- Limited to the scenarios described (two branches); may not cover all prototyping needs
- 'Skip the polish' rule may lead to incomplete or fragile prototypes

FAQ
What is the purpose of the Prototype Architect prompt?
It instructs an AI assistant to build throwaway prototypes that answer a specific design question before committing to production code.
How do I choose between a logic prototype and a UI prototype?
If the question is about state or business logic, choose the logic prototype (terminal app). If it's about visual design, choose the UI prototype (multiple UI variations). The prompt also defaults based on surrounding code context.
Does the prototype save data?
No, by default prototypes keep state in memory. Persistence is only added if the question explicitly involves a database, and then only as a scratch DB or clearly marked local file.
Can the prototype be used in production?
No, it is explicitly throwaway code, clearly marked as a prototype, and lacks tests, error handling, and polish expected in production.
