Stream Coding v3.4

The 10-20x Methodology for AI-Accelerated Software Development

📢 v3.4 Update: Complete 13-item Clarity Gate (was 5 items), scoring rubric, Documentation Audit. Re-download if using older version.

✅ This methodology built 7 production modules in 4.5 hours (5Levels Case Study, Git-verified)

"Stream coding isn't about faster coding. It's about documentation so clear that code writes itself."

The Problem: The Velocity Mirage

AI tools promise 10x productivity. GitHub Copilot, Cursor, Claude Code—they make coding 55% faster.

But projects still take the same time to ship.

Why? Because faster typing doesn't solve:

• Strategic decisions AI can't make for you
• Context that gets lost between prompts
• Technical debt created at 10x speed

This gap between task velocity and project velocity is the Velocity Mirage.

The Solution: Stream Coding

Stream Coding is a documentation-first methodology that makes AI-generated code deterministic.

The 40/40/20 Split:

• 40% Strategic Thinking (Phase 1) — Solve hard problems before coding
• 40% AI-Ready Documentation (Phase 2) — Specs so complete AI has zero decisions
• 20% Execution + Quality (Phases 3-4) — Code streams out automatically

Real Results (5Levels Case Study):

• 7 production modules in 4.5 hours
• 46 intelligence endpoints (77 total backend API)
• Zero bugs in generated code, 21 minutes average per tested module

Note: The case study focuses on backend intelligence modules—Stream Coding's sweet spot. For frontend, use the methodology for behavior (components, state, logic) and complement with AI design tools for visuals. See Chapter 4 for details.

Quick Start

Option 1: Claude.ai / Claude Desktop

1. Download stream-coding.skill
2. Go to Settings → Features → Skills → Add
3. Upload the .skill file
4. Ask Claude: "Build a user authentication system"

Option 2: Claude Code

Clone the repo — Claude Code auto-detects skills in .claude/skills/:

git clone https://github.com/frmoretto/stream-coding
cd stream-coding
# Claude Code will automatically detect .claude/skills/stream-coding/SKILL.md

Or copy .claude/skills/stream-coding/ to your project's .claude/skills/ directory.

Ask Claude: "Build a user authentication system"

Option 3: Claude Projects

Add SKILL.md to project knowledge. Claude will search it when needed, though Skills provide better integration.

Option 4: OpenAI Codex / GitHub Copilot

Copy the canonical skill to the appropriate directory:

Use skills/stream-coding/SKILL.md (agentskills.io format).

Option 5: Manual / Other LLMs

For Cursor, Windsurf, or other AI tools:

• Extract core principles (Phases, Document Types, Clarity Gate)
• Create a condensed version for .cursorrules or project settings
• Use the templates and Clarity Gate Checklist as reference

The methodology is tool-agnostic—only SKILL.md is Claude-optimized.

The Core Insight

"When code fails, fix the spec—not the code."

Traditional development iterates on code. Stream Coding iterates on do
