...Became a Masterclass in Documentation-Driven Development​

Timeline of Productivity​

Phase 1: Initial Success (0-30 min)​

  • ✅ Voice input working with push-to-talk
  • ✅ Real-time transcription via OpenAI
  • ✅ Agent responses to voice input
  • 🎉 "Hello Nova, can you hear me?" → Success!

Phase 2: The Discovery (30-45 min)​

  • ❌ WebSocket routes with colons don't deploy
  • 🔍 Error: "The provided route key is not formatted properly"
  • 💡 Realization: AWS API Gateway doesn't support : in routes
  • 🔄 SST begins 30-minute rollback process

Phase 3: Productive Waiting (45-90 min)​

Instead of idle waiting, we:

Created Documentation​

  1. Voice Agents Comprehensive Guide - Consolidated 3 scattered documents
  2. Voice Deployment Lessons - Captured the colon routing issue
  3. Voice Session Summary - This very document!

Updated Project Infrastructure​

  1. Cursor Rules - Added WebSocket routing warnings
  2. Code Fixes - Replaced all colons with dots
  3. Type Updates - Fixed all action constants

Planned Future Work​

  1. Hybrid Voice Mode - Decouple input from output
  2. Smart Silence Detection - Auto-stop after quiet
  3. Context-Aware Responses - Length-based audio rules

Key Accomplishments​

Technical Fixes​

// ❌ Before
'voice:session:start': { ... }

// ✅ After  
'voice.session.start': { ... }

Documentation Created​

  • 4 new comprehensive guides
  • 3 Cursor rule files
  • 2 major documentation consolidations
  • 1 visual process diagram

Knowledge Captured​

  • WebSocket route naming restrictions
  • Session connection timing requirements
  • Handler configuration completeness
  • Productive waiting strategies

The Meta-Lesson​

Every moment of development can be productive.

While waiting for infrastructure:

  • Document what you just learned
  • Consolidate scattered knowledge
  • Create guides for future developers
  • Update project best practices

Impact​

This session transformed a frustrating rollback into:

  • Permanent knowledge capture
  • Better project documentation
  • Improved development practices
  • Cursor rules preventing future issues

The Beautiful Irony​

The 30-minute delay that could have been wasted became the catalyst for establishing our documentation-driven development practice. The rollback didn't slow us down - it made the project permanently better.

Next Session Benefits​

Future developers will:

  • Never use colons in WebSocket routes (Cursor rule warns them)
  • Have comprehensive voice implementation guide
  • Understand the architecture deeply
  • Know how to be productive during deployments
