How This Module Was Made

Consolidation of markdown utilities from blog_writer and article_illustrator

---

The Problem

Both scenario tools processed markdown but implemented their own utilities:

• blog_writer: Title extraction, slugification
• article_illustrator: Structure parsing, image insertion, content analysis

This duplication meant:

• Other apps couldn't reuse these utilities
• No consistency across tools
• Missed opportunity for shared module

---

The Solution: Consolidate as Reusable Module

What We Extracted:

• From blog_writer: extract_title_from_markdown(), slugify()
• From article_illustrator: MarkdownParser, MarkdownImageUpdater, structure analysis

Total: ~400 LOC consolidated from two sources

Design Decisions

Decision 1: Functions vs Classes

Chose: Functions for simple ops (extract, slugify), classes for complex (parse, update) Why: Simpler interface, no unnecessary classes

Decision 2: No Async

Chose: Synchronous interface Why: Markdown processing is CPU-bound, not I/O

Decision 3: Flexible Placement

Chose: Support multiple placement strategies (before/after section, at line) Why: Different use cases need different insertion logic

Reusability

Use cases:

• Blog post formatters
• Documentation generators
• README creators
• Wiki page builders
• Any markdown manipulation
