Stream Coding

The 10-20x Methodology for AI-Accelerated Development

Documentation-first development methodology.
When docs are clear enough, code generation becomes automatic.

The Velocity Mirage

Everyone codes faster. Nobody ships faster.

What AI Tools Promise

  • • 10x faster coding
  • • Instant implementation
  • • Ship in days, not weeks
⚠️

What Actually Happens

  • • Fast code generation
  • • Slow overall progress
  • • 2 weeks coding → 3 weeks refactoring

The METR Study (July 2025): Experienced developers were 19% slower with AI tools—despite reporting they felt 20% faster.

That's a 39-point perception-reality gap. The velocity mirage isn't theory. It's measurable reality.

Git-Verified Proof

Not theory. Not estimates. Actual commit timestamps.

The Stream Coding Methodology

Four phases. Systematic. Proven.

"Documentation IS the real work. Code is just the printout."

🎯
PHASE 1 • 40%

Strategic Product Thinking

Define what you're building and why. Clear requirements before code.

📝
PHASE 2 • 40%

AI-Ready Documentation

Specs so clear AI can generate correct code automatically.

PHASE 3 • 20%

Rapid Execution Workflow

Code streams out because documentation was clear.

ONGOING

Quality Control

Two-gate system prevents problems before they occur.

The Paradigm Shift

Traditional: Write code → Fix bugs → Refactor → Document

Stream Coding: Document → AI generates code → Ship with confidence

The 5Levels Case Study

From strategic blueprint to production in 5.5 weeks

📋

Phase 1: Strategic Thinking (~4 weeks)

Designed two-layer architecture. Defined intelligence modules. Established quality gates. Created strategic blueprint.

~4 weeks
📝

Phase 2: Documentation (~1 week)

Wrote 24 specification files. Every endpoint documented. Database schema defined. Implementation details clear.

~1 week

Phase 3: Execution (4 hours 34 minutes)

7 modules. 46 endpoints. Zero bugs. Peak velocity: 17 minutes per module.
