# stream-coding

stream-coding turns coding work into a documentation-first flow. It helps prepare specifications that an AI agent can execute with fewer open decisions.

## What it does

stream-coding treats documentation as the main input for code generation. It starts with the product intent and separates documents by purpose: strategic documents cover what and why, implementation documents describe how, and reference documents hold lookup material. Anti-patterns, test cases, and error handling belong in implementation documents rather than being copied into strategic ones.

The workflow checks a specification with a 13-item Spec Gate, then uses the separate Clarity Gate and an adversarial review before execution. The review looks for contradictions, unsupported claims, and choices an agent would have to make on its own. Critical findings must be fixed before coding. Phase 2.5 requires a different AI model or a trusted human reviewer, so a single-model review does not match this process.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add frmoretto/stream-coding --skill stream-coding -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/stream-coding/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/stream-coding/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add frmoretto/stream-coding --skill stream-coding -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/stream-coding/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add frmoretto/stream-coding --skill stream-coding -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/stream-coding/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install frmoretto/stream-coding stream-coding
```

2. **Manually: put the files in place**
- File: `.github/skills/stream-coding/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add frmoretto/stream-coding --skill stream-coding -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/frmoretto/stream-coding
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/stream-coding/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add frmoretto/stream-coding --skill stream-coding -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/frmoretto/stream-coding/tree/HEAD/SKILL.md

## When to use it
- turn product intent into an executable specification
- place requirements in the right document type
- score a specification with the 13-item Spec Gate
- expose contradictions before implementation
- record decisions for critical and high-priority findings

## Example prompts
- Build the order import flow, then prepare its specification with the stream-coding method before writing code.
- Document the API for this module, run the Spec Gate, and list every decision an agent would still need to make.
- Implement the feature only after an external reviewer has run Phase 2.5 and all critical findings are fixed.

name: stream-coding
description: Documentation-first development methodology. The goal is AI-ready documentation - when docs are clear enough, code generation becomes automatic. Triggers on "Build", "Create", "Implement", "Document", or "Spec out". Version 3.5 adds Phase 2.5 Adversarial Review and renames internal verification to Spec Gate (structural completeness). Clarity Gate is now a separate standalone tool for epistemic quality.

# Stream Coding v3.5: Documentation-First Development

## ⚠️ CRITICAL REFRAME: THIS IS A DOCUMENTATION METHODOLOGY, NOT A CODING METHODOLOGY

**The Goal:** AI-ready documentation. When documentation is clear enough, code generation becomes automatic.

**The Insight:**
> "If your docs are good enough, AI writes the code. The hard work IS the documentation. Code is just the printout."

**v3.5 Core Additions:**
1. Phase 2.5 Adversarial Review — stress-test specs with a hostile critic before execution. New time allocation: 40/40/5/10/5.
2. Renamed internal 13-item checklist to **Spec Gate** (structural completeness for code generation)

> **Two-gate pipeline — know the difference:**
> - **Spec Gate** (13 items, this skill) → *"Can AI execute this without asking questions?"*
> - **Clarity Gate** (9 points, separate tool) → *"Will AI mistake assumptions for facts?"*
>
> Spec Gate → Clarity Gate → Adversarial Review → Verified Specification → Execution

## CHANGELOG

| Version | Changes |
|---------|---------|
| 3.0 | Initial Stream Coding methodology |
| 3.1 | Clearer terminology, mandatory Spec Gate |
| 3.3 | Document-type-aware placement (Anti-patterns, Test Cases, Error Handling in implementation docs) |
| 3.3.1 | Corrected time allocation (40/40/20), added Phase 4, added Rule of Divergence |
| 3.4 | Complete 13-item Spec Gate, scoring rubric with weights, self-assessment questions, 4 mandatory section templates, Documentation Audit integrated into Phase 1 |
| **3.5** | **Phase 2.5 Adversarial Review added. New time allocation: 40/40/5/10/5. Internal 13-item checklist renamed from "Clarity Gate" → "Spec Gate". Two-gate pipeline documented: Spec Gate (structural) + Clarity Gate standalone (epistemic).** |

## THE STREAM CODING TRUTH

```
Messy Docs → Vague Specs → AI Guesses → Rework Cycles → 2-3x Velocity
Clear Docs → Clear Specs → AI Executes → Minimal Rework → 10-20x Velocity
```

**Why Most "AI-Assisted Development" Fails:**
- People feed AI messy docs
- AI generates code based on assumptions
- Code doesn't match intent
- Endless revision cycles
- Result: Marginally faster than manual coding

**Why Stream Coding Achieves 10-20x:**
- Documentation is clarified FIRST
- AI has zero ambiguity
- Code matches intent on first pass
- Minimal revision
- Result: Documentation time + automatic code generation
