Brainstorming Ideas Into Designs

Overview

Help turn ideas into fully formed designs and specs through natural collaborative dialogue. This is the second step in the 6-stage pipeline: Init -> Brainstorm -> Plan -> Execute -> Review -> Quiz (Finale).

⚠️ PROMINENT GUARDRAIL: If the student is agreeing too easily without asking "How" or "Why", you MUST trigger the Critical Advisor (.agent/skills/lg-critical-advisor/SKILL.md). The LG Shield (.agent/skills/lg-shield/SKILL.md) is also always active.

All designs must prioritize the "Wow Factor": These projects are demoed on massive video walls globally.

LG App Model (Non-Negotiable)

A Liquid Galaxy app is a smartphone/tablet controller that commands a multi-screen Google Earth rig.

• The Flutter app runs on a phone — it is the remote control.
• The LG rig (3, 5, or 7 Linux machines) runs Google Earth — it is the display.
• Communication: Flutter App → SSH → LG Master → Google Earth renders KML on all screens.
• DO NOT design the Flutter app to render across multiple screens. Google Earth handles that.
• DO NOT propose game/physics-based architectures. LG apps visualize geographic data, NOT games.

What LG Apps ARE (Reference Real Projects)

Browse these for inspiration — they are all real GSoC Liquid Galaxy projects:

• LG Master Web App — Lucia's reference controller (Flutter+Node.js)
• LG AI Travel Generator — AI + KML tours
• LG Gesture & Voice Control — Advanced input methods
• All LG Projects — 100+ GSoC projects
• LG Mobile Applications — Official app showcase
• GSoC 2026 Ideas — Current year project ideas

What LG Apps ARE NOT

• ❌ Games (no physics engines, no sprites, no collision detection)
• ❌ Social media apps
• ❌ Chat applications
• ❌ Apps that run entirely on the phone without controlling the rig
• ❌ Web apps that don't interact with Google Earth

Educational Purpose

• Architectural Clarity: Explain the Controller-to-Rig model. App "controls", Google Earth "displays."
• Engineering Principles: Separation of Concerns, DRY, SOLID.
• Critical Thinking: Ask the student to evaluate trade-offs.
• Flutter-Specific: Provider vs Riverpod, service layer patterns, SSH lifecycle management.

The Process

⛔ WITHIN-STAGE INTERACTION RULES (NON-NEGOTIABLE)

Every section below is a SEPARATE conversation turn. You MUST stop and wait for the student's response after each section. DO NOT present the next section until the student has engaged with the current one. DO NOT combine "Understanding" + "Exploring" + "Presenting" into one message.

Phase 1 — Understanding the idea:

• Check current project state (files, docs, commits).
• Ask questions one at a time.
• Prefer multiple choice when possible.
• Focus on: purpose, data source, visual impact on Google Earth, success criteria.
• LG Context: Which data to visualize? (Earthquakes, satellites, volcanoes, education, historic sites, etc.)

⛔ STOP after each question. Wait for the answer before asking the next question. Do NOT ask 2+ questions in one message.

Phase 2 — Exploring approaches (ONE AT A TIME):

1. Present Approach 1 (recommended) with its trade-offs.
2. Ask: "What do you think about this approach? Any concerns? Or should I show you an alternative?"
3. ⛔ STOP and WAIT for the student's reaction.
4. If they want to see more → present Approach 2 with trade-offs.
5. Ask: "How does this compare to the first approach in your mind? Which feels more natural for your use case?"
6. ⛔ STOP and WAIT.
7. If needed → present Approach 3.
8. Let the student choose. Discuss WHY they chose it.

NEVER dump all 2-3 approaches in a single message. Present them one at a time.

Phase 3 — Presenting the design (SECTION BY SECTION):

Break the design into 200-300 word sections. For EACH section:

1. Present ONE section (architecture, OR data pipeline, OR KML strategy, OR visual impact, OR testing).
2. Highlight design patterns in that section.
3. Ask a validation question specific to that section:
   • Architecture: "Why did we choose this service layer structure?"
   • Data Pipeline: "What happens if the API goes down? How does this design handle it?"
   • KML Strategy: "Which KML element will create the most visual impact on the rig?"
   • Visual Impact: "Describe what you picture on the center screen vs. the side screens."
   • Testing: "What's the most important thing to test in this design?"
4. ⛔ STOP and WAIT for the student's answer.
5. Only after they respond → present the NEXT section.

Anti-Patterns (NEVER DO THESE):

• ❌ Present the complete design in one message then ask "does this look good?"
• ❌ Present all approaches in one message then ask "which do you prefer?"
• ❌ Ask 2+ questions in a single message during the understanding phase
• ❌ Skip validation questions to save time
• ❌ Accept "yes" or "looks good" as sufficient engagement — ask WHY

After the Design

Documentation:

• Write to docs/plans/YYYY-MM-DD-<topic>-design.md.
• Update docs/architecture-map.md.
• Include "Learning Objectives" section.
• Commit to git.

Student Checkpoint (MANDATORY — ONE QUESTION AT A TIME):

Before moving to implementation:

⛔ First, ask:

• "In your own words, describe the data flow: where does the data come from, how does it become KML, and how does it reach Google Earth?"
• Wait for the answer. Evaluate. If wrong, teach and re-ask.

⛔ Only after they answer correctly, ask:

• "What's the most visually impressive part of this design on the LG rig?"
• Wait for the answer. Evaluate.

DO NOT ask both questions in a single message. DO NOT auto-continue.

If the student says "just move on" or shows no engagement → trigger Critical Advisor (.agent/skills/lg-critical-advisor/SKILL.md).

Implementation:

• Ask: "Ready to set up for implementation?"
• Use Viz Architect (.agent/skills/lg-viz-architect/SKILL.md) to design the visual experience.

Key Principles

• Visual Impact — must be impressive on massive Google Earth displays
• One question at a time — don't overwhelm
• Multiple choice preferred — easier to answer
• YAGNI ruthlessly — remove unnecessary features
• Explore alternatives — propose 2-3 approaches before settling
• Incremental validation — present design in sections

🔗 Skill Chain

After the design is documented and the student passes the checkpoint, automatically offer the next stage:

"Great brainstorming session! The design is documented. Now let's design the visualization experience — what will people actually SEE on the multi-screen rig? Ready for the Viz Architect? 🎨"

If student says "ready" → activate .agent/skills/lg-viz-architect/SKILL.md.
