• userstories.md (combined user docs for Replit)

🚀 STEP 6: Start Fresh Development in Replit

What You're Doing:

Using your new documentation to rebuild your project properly with AI.

Action Steps:

6.1 Create New Replit Project (5 minutes)

1. Go to Replit.com
2. Create a NEW project (don't use your old messy one)
3. Name it "[Your Project Name] v2" or something similar
4. Choose the appropriate template for your tech stack

6.2 Upload Your Documentation (5 minutes)

1. In your new Replit project, upload these files:
   • replitrules.md
   • userstories.md
2. Keep your other documentation files handy on your computer

6.3 Launch Development with Master Prompt (5 minutes)

1. Open the chat in your new Replit project
2. Copy your Master Launch Prompt from ai-prompts.md
3. Paste it into Replit chat
4. Press Enter and wait for Replit to respond

Replit should:

• Acknowledge the project scope
• Set up the initial project structure
• Ask for Phase 1 detailed instructions

6.4 Begin Phase 1 Development (Variable time)

1. When Replit asks for Phase 1 details:
2. Copy your Phase 1 Detailed Prompt from ai-prompts.md
3. Paste it into Replit chat
4. Let Replit start building the foundation

Monitor the progress and answer any questions Replit asks.

6.5 Validate Phase 1 Completion (30 minutes)

1. When Replit says Phase 1 is complete:
2. Open your testing-checklists.md file
3. Go through the Phase 1 checklist item by item
4. Test each feature manually
5. Check off each item that works

If anything doesn't work:

• Tell Replit specifically what's broken
• Ask Replit to fix it
• Test again

Don't proceed to Phase 2 until everything on the Phase 1 checklist works.

6.6 Continue Phase by Phase (Repeat process)

1. Phase 2: Use Phase 2 prompt when Phase 1 is validated
2. Phase 3: Use Phase 3 prompt when Phase 2 is validated
3. Phase 4: Use Phase 4 prompt when Phase 3 is validated

🔧 WHEN THINGS GO WRONG (Troubleshooting)

If Replit Gets Confused:

Copy this reset prompt into Replit:

Let's refocus on the current phase. Based on the replitrules.md and userstories.md files:

PROJECT: [Your project name]
CURRENT PHASE: [Phase 1, 2, 3, or 4]
ISSUE: [Describe what's not working]

Please review the specifications and continue with exactly what's defined for this phase. Ask specific questions if you need clarification on any requirement.

If You Need to Update Your Documentation:

Go back to Claude and ask:

I'm in the middle of development and discovered something new about my project:

NEW INFORMATION: [Describe what you learned]
CURRENT DOCUMENTATION: [Paste relevant section from your docs]

How should I update my specifications to include this new information? Should this change my MVP scope or just the implementation details?

If Development Gets Stuck:

1. Check your testing checklist - what specifically isn't working?
2. Ask Replit very specific questions about the error or issue
3. Reference your user stories to clarify what the expected behavior should be
4. Break large requests into smaller, specific tasks

If You Want to Add Features:

DON'T add new features until all 4 phases are complete.

Save new ideas for "Version 2" - focus on getting your MVP working first.
