Chapter 2: Multi-Dimensional Requirement Review — The GStack Brainstorm

⏱ Est. reading time: 10 min Updated on 5/17/2026

What You Will Learn

  • Using GStack to simulate multiple professional roles.
  • Conducting a requirement review from CEO, Designer, and Engineer perspectives.
  • Refining "NodeFlow" project features through cross-role collision.

2.1 Why Multi-Persona Review?

Traditional requirement gathering is often one-sided. GStack allows you to "hire" a virtual executive team to poke holes in your plan early.

The Personas

  1. The CEO: Focuses on value, user retention, and "The Big Picture".
  2. The Designer: Focuses on UX, visual hierarchy, and emotional connection.
  3. The Engineer: Focuses on feasibility, performance, and technical debt.

2.2 Running the Review

In your terminal, describe your idea for NodeFlow:

"I want to build a node-based note-taking app where users can link ideas visually."

Then, invoke GStack:

/brainstorm

GStack will generate a dialogue between these personas. You might hear:

  • CEO: "Can we export these nodes to PDF for business reports?"
  • Designer: "The connections need to be smooth curves, not jagged lines, to reduce cognitive load."
  • Engineer: "We should use a Canvas-based rendering engine for better performance with 100+ nodes."

2.3 Finalizing the Spec

After the brainstorming session, ask Claude to summarize the "Winning Spec":

/summarize-spec

This ensures everyone (including the AI) is aligned on exactly what needs to be built.

Summary

By colliding different perspectives, we've transformed a vague idea into a solid, reviewed specification. Next, we'll turn this spec into a stunning visual reality.
