Post Structure

# Title: [Technical Concept] — [Subtitle/Core Value]

> Date: YYYY-MM-DD | Author: geode-team | Tags: [tag1, tag2]

## Table of Contents
1. Introduction (Problem definition)
2~N. Body sections (Architecture → Implementation → Verification)
N+1. Wrap-up (Summary table + Checklist)

---

## 1. Introduction

Problem definition in 1 paragraph → Solution strategy in 1 paragraph.
Make clear "why the reader should read this."

## 2~N. Body

### Section title: "N. Concept Name + Detailed Description"

Each section pattern:
1. One-line concept summary
2. Architecture diagram (Mermaid or ASCII)
3. Core code block (Python, with type hints)
4. > Design intent commentary block
5. Comparison table (config values, trade-offs, etc.)

## N+1. Wrap-up

Code Block Rules

1. Interface/Protocol first → Implementation later
2. Type hints must be included
3. > quote block immediately after code block explaining "why this design"
4. File path as comment above code block: # geode/infrastructure/ports/llm_port.py

# geode/infrastructure/ports/llm_port.py
class LLMClientPort(Protocol):
    def generate(self, system: str, user: str, **kwargs) -> str: ...
    def generate_json(self, system: str, user: str, **kwargs) -> dict: ...

By abstracting the concrete LLM call implementation (Claude, GPT), models can be swapped by simply replacing the adapter. This is a design decision following the Hexagonal Architecture Port/Adapter pattern.

Diagram Rules

• Prefer Mermaid (GitHub rendering compatible)
• Use ASCII diagrams alongside for complex flows
• 1-2 sentence explanation of core flow immediately after diagram
• Colors: Tailwind CSS based (fill:#3B82F6, fill:#10B981, etc.)

Length Guide

Type	Length	Code:Explanation ratio
Concept introduction	3000-5000 chars	3:7
Architecture deep-dive	6000-10000 chars	4:6
Implementation tutorial	8000-12000 chars	6:4

Korean Technical Terminology Rules

• English technical terms: Korean annotation on first appearance: "Port(포트)"
• Thereafter use English original: "Port"
• Proper nouns (LangGraph, Anthropic, FastMCP) always in English
• Abbreviations: spell out on first appearance: "PSI(Population Stability Index)"
