### Personal Writing Style Guide

Source: https://context7.com/sugarforever/01coder-agent-skills/llms.txt

Provides a quick reference for punctuation, article structure, and YAML frontmatter conventions for Chinese content. Ensures consistent formatting and prose style.

```markdown
<!-- Punctuation quick reference -->

| Element        | Use          | Avoid        |
|----------------|--------------|--------------|
| Dash           | ` - ` (space-hyphen-space) | `——` |
| Ellipsis       | `......`     | `……`        |
| Quotes (body)  | `""` curved  | `""` straight|

<!-- Article structure principle -->
- No numbered scaffolding or explicit "总结" sections
- Paragraphs flow as natural prose; transitions bridge topics
- Technical names and code use ASCII; body text uses Chinese punctuation

<!-- YAML frontmatter always uses straight ASCII quotes -->
