# Habilidade Obsidian Flavored Markdown

Esta habilidade permite que o Claude Code crie e edite Markdown válido com suporte a Obsidian, incluindo todas as extensões de sintaxe específicas do Obsidian.

## Visão Geral

O Obsidian usa uma combinação de variantes de Markdown:
- [CommonMark](https://commonmark.org/)
- [GitHub Flavored Markdown](https://github.github.com/gfm/)
- [LaTeX](https://www.latex-project.org/) para matemática
- Extensões específicas do Obsidian (wikilinks, callouts, embeds, etc.)

## Formatação Básica

### Parágrafos e Quebras de Linha

```markdown
This is a paragraph.

This is another paragraph (blank line between creates separate paragraphs).

For a line break within a paragraph, add two spaces at the end  
or use Shift+Enter.
```

### Títulos

```markdown
# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6
```

### Formatação de Texto

| Estilo | Sintaxe | Exemplo | Resultado |
|--------|---------|---------|-----------|
| Negrito | `**text**` ou `__text__` | `**Bold**` | **Bold** |
| Itálico | `*text*` ou `_text_` | `*Italic*` | *Italic* |
| Negrito + Itálico | `***text***` | `***Both***` | ***Both*** |
| Tachado | `~~text~~` | `~~Striked~~` | ~~Striked~~ |
| Destaque | `==text==` | `==Highlighted==` | ==Highlighted== |
| Código inline | `` `code` `` | `` `code` `` | `code` |

### Escapando Formatação

Use barra invertida para escapar caracteres especiais:
```markdown
\*This won't be italic\*
\#This won't be a heading
1\. This won't be a list item
```

Caracteres comuns a escapar: `\*`, `\_`, `\#`, `` \` ``, `\|`, `\~`

## Links Internos (Wikilinks)

### Links Básicos

```markdown
[[Note Name]]
[[Note Name.md]]
[[Note Name|Display Text]]
```

### Link para Títulos

```markdown
[[Note Name#Heading]]
[[Note Name#Heading|Custom Text]]
[[#Heading in same note]]
[[##Search all headings in vault]]
```

### Link para Blocos

```markdown
[[Note Name#^block-id]]
[[Note Name#^block-id|Custom Text]]
```

Defina um ID de bloco adicionando `^block-id` ao final de um parágrafo:
```markdown
This is a paragraph that can be linked to. ^my-block-id
```

Para listas e citações, adicione o ID do bloco em uma linha separada:
```markdown
> This is a quote
> With multiple lines

^quote-id
```

### Links de Busca

```markdown
[[##heading]]     Search for headings containing "heading"
[[^^block]]       Search for blocks containing "block"
```

## Links no Estilo Markdown

```markdown
[Display Text](Note%20Name.md)
[Display Text](Note%20Name.md#Heading)
[Display Text](https://example.com)
[Note](obsidian://open?vault=VaultName&file=Note.md)
```

Nota: Espaços devem ser codificados como `%20` em links Markdown.
