SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build a throwaway prototype to de-risk a design decision before committing to production code. Use for state-machine validation, API ergonomics testing, UI layout exploration, or algorithmic feasibility. The prototype is explicitly disposable — no tests, no types, no polish. Goal is learning speed, not shipping quality.

Core Features & Use Cases

  • Disposable by design: single-purpose exploration that can be deleted after findings.
  • Time-boxed workflows: clear duration and deliverables to minimize drift.
  • Findings preserved: document outcomes in PROTOTYPE_FINDINGS.md to inform production decisions.
  • Support for radical variations: compare approaches (A/B) to reveal trade-offs.

Quick Start

Open a disposable prototype session, define one falsifiable question, time-box the exercise to 15–25 minutes, and document findings in PROTOTYPE_FINDINGS.md before deleting the prototype.

Frequently Asked Questions about prototype

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate a state machine design before writing production code?▼

Test API ergonomics by prototyping the interface with minimal dependencies and no polish, focusing purely on how the API feels to consume. You time-box the exercise to 15–25 minutes and record whether the design decisions are viable in a dedicated findings file.

What is the best way to run a throwaway prototype for algorithm feasibility checks?▼

Run a throwaway prototype by defining a single focused question, setting a clear 15–25 minute duration, and building a disposable script with no production polish. You preserve the trade-offs and outcomes in PROTOTYPE_FINDINGS.md to inform your real implementation.

Can I use disposable prototyping to compare A/B UI layout experiments?▼

Disposable prototyping supports radical variations to compare A/B UI layout experiments and reveal trade-offs. You can explore multiple approaches quickly, ensuring each prototype remains single-purpose and explicitly disposable to prevent drift into production code.

When should I not use throwaway prototypes for design exploration?▼

Do not use throwaway prototypes when you need shipping quality, comprehensive tests, or strict type safety, because the workflow is explicitly designed to skip polish. If your task lacks a single falsifiable question or cannot be time-boxed, prototyping will likely drift.

Do I need to set up dependencies to test design decisions with a prototype?▼

You should keep dependencies minimal when testing design decisions with a prototype to ensure disposability and fast iteration. The goal is learning speed through a single focused exploration, so you avoid heavy setups and document findings in PROTOTYPE_FINDINGS.md before deleting the code.
