-## Properties
+Supported operators: `==`, `!=`, `>`, `<`, `>=`, `<=`, `&&`, `||`, `!`
-### Three Types of Properties
+For complete filter syntax and patterns, see [Filters](filters.md).
-1. **Note properties** - From frontmatter: `note.author` or just `author`
-2. **File properties** - File metadata: `file.name`, `file.mtime`, etc.
-3. **Formula properties** - Computed values: `formula.my_formula`
-
-### File Properties Reference
-
-| Property | Type | Description |
-|----------|------|-------------|
-| `file.name` | String | File name |
-| `file.basename` | String | File name without extension |

+## Formulas
-### The `this` Keyword
+Formulas compute dynamic values from properties. Define them once and use across all views.
-- In main content area: refers to the base file itself
-- When embedded: refers to the embedding file
-- In sidebar: refers to the active file in main content
-
-## Formula Syntax
-
-Formulas compute values from properties. Defined in the `formulas` section.
+**Example:**
```yaml
formulas:
- # Simple arithmetic
- total: "price * quantity"
-
- # Conditional logic
- status_icon: 'if(done, "โ
", "โณ")'
-
- # String formatting
- formatted_price: 'if(price, price.toFixed(2) + " dollars")'
-
- # Date formatting
- created: 'file.ctime.format("YYYY-MM-DD")'
-
- # Complex expressions
- days_old: '((now() - file.ctime) / 86400000).round(0)'
-```

## Embedding Bases
-Embed in Markdown files:
+Embed a base file in Markdown notes:
```markdown
![[MyBase.base]]
-
-![[MyBase.base#View Name]]
+![[MyBase.base#View Name]] # Specific view
```
## YAML Quoting Rules
-- Use single quotes for formulas containing double quotes: `'if(done, "Yes", "No")'`
-- Use double quotes for simple strings: `"My View Name"`
+- Use **single quotes** for formulas containing double quotes: `'if(done, "Yes", "No")'`
+- Use **double quotes** for simple strings: `"My View Name"`
- Escape nested quotes properly in complex expressions

+# Obsidian Bases: Filters
+
+Filters narrow down results to show only matching items. They can be applied globally (to all views) or per-view.
+
+## Filter Structure
+
+### Single Filter String
+
+```yaml
+filters: 'status == "done"'
+```
+
+### AND - All Conditions Must Be True
+
+```yaml
+filters:
+ and:
+ - 'status == "done"'
+ - "priority > 3"
+```
+
+### OR - Any Condition Can Be True
+
+```yaml
+filters:
+ or:
+ - 'file.hasTag("book")'
+ - 'file.hasTag("article")'
+```
+
+### NOT - Exclude Matching Items
+
+```yaml
+filters:
+ not:
+ - 'file.hasTag("archived")'
+```
+
+### Nested Filters
+
+Combine conditions with nested logic:
+
+```yaml
+filters:
+ or:
+ - file.hasTag("tag")
+ - and:
+ - file.hasTag("book")
+ - file.hasLink("Textbook")
+ - not:
+ - file.hasTag("book")
+ - file.inFolder("Required Reading")
+```
+
+## Filter Operators
+
+| Operator | Description |
+| -------------- | --------------------- |
+| `==` | equals |
+| `!=` | not equal |
+| `>` | greater than |
+| `<` | less than |
+| `>=` | greater than or equal |
+| `<=` | less than or equal |
+| `&&` | logical and |
+| `\|\|` | logical or |
+| ! | logical not |
+
+## Common Filter Patterns
+
+### Filter by Tag
+
+```yaml
+filters:
+ and:
+ - file.hasTag("project")
+```
+
+### Filter by Folder
+
+```yaml
+filters:

+ - 'file.mtime > now() - "7d"'
+```
+
+### Filter by Property Value
+
+```yaml
+filters:
+ and:
+ - 'status == "active"'
+ - "priority >= 3"
+```
+
+### Combine Multiple Conditions
+
+```yaml
+filters:
+ or:
+ - and:
+ - file.hasTag("important")
+ - 'status != "done"'
+ - and:
+ - "priority == 1"
+ - 'due != ""'

+
+ # Conditional logic
+ status_icon: 'if(done, "โ
", "โณ")'
+
+ # String formatting
+ formatted_price: 'if(price, price.toFixed(2) + " dollars")'

+```
+
+## YAML Quoting Rules
+
+- Use **single quotes** for formulas containing double quotes: `'if(done, "Yes", "No")'`
+- Use **double quotes** for simple strings: `"My View Name"`
+- Escape nested quotes properly in complex expressions
+
+## Formula Functions
+
+For a complete reference of available functions, see [Functions Reference](functions-reference.md).
+
+### Global Functions
+
+| Function | Description |
+| ------------- | --------------------------------------------------- |
+| `date()` | Parse string to date. Format: `YYYY-MM-DD HH:mm:ss` |
+| `duration()` | Parse duration string |
+| `now()` | Current date and time |
+| `today()` | Current date (time = 00:00:00) |
+| `if()` | Conditional |
+| `min()/max()` | Smallest/largest number |
+| `number()` | Convert to number |
+| `link()` | Create a link |
+
+### Date Arithmetic
+
+Duration units: `y/year/years`, `M/month/months`, `d/day/days`, `w/week/weeks`, `h/hour/hours`, `m/minute/minutes`, `s/second/seconds`
+
+```yaml
+# Add/subtract durations
+"date + \"1M\"" # Add 1 month
+"date - \"2h\"" # Subtract 2 hours
+"now() + \"1 day\"" # Tomorrow
+"today() + \"7d\"" # A week from today
+
+# Subtract dates for millisecond difference
+"now() - file.ctime"
+
+# Complex duration arithmetic
+"now() + (duration('1d') * 2)"
+```
+
+## Formula Examples
+
+### Status Indicators
+
+```yaml
+priority_label: 'if(priority == 1, "๐ด High", if(priority == 2, "๐ก Medium", "๐ข Low"))'
+is_overdue: 'if(due, date(due) < today() && status != "done", false)'
+```
+
+### Date Calculations
+
+```yaml
+days_until_due: 'if(due, ((date(due) - today()) / 86400000).round(0), "")'
+days_old: "((now() - file.ctime) / 86400000).round(0)"
+day_of_week: 'date(file.basename).format("dddd")'
+```
+
+### String Operations
+
+```yaml
+formatted_date: 'file.ctime.format("MMM DD, YYYY")'
+reading_time: 'if(pages, (pages * 2).toString() + " min", "")'
+word_estimate: "(file.size / 5).round(0)"
+```
+
+### Counting and Stats
+
+```yaml
+link_count: "file.links.length"
+tag_count: "file.tags.length"
+has_content: "file.size > 100"
+```
+
+## Using Formulas in Views
+
+Reference formulas in view properties using the `formula.` prefix:
+
+```yaml
+views:
+ - type: table
+ name: "Active Tasks"
+ order:
+ - file.name
+ - status
+ - formula.priority_label # Reference defined formula
+ - due
+ - formula.days_until_due # Reference another formula
+```
+
+## Performance Tips
+
+- Keep formulas simple for faster calculation
+- Use conditional logic to avoid unnecessary computations
+- Cache repeated calculations by defining them once as formulas
+- Avoid deeply nested conditions (keep 2-3 levels max)
+

+# Obsidian Bases: Views
+
+Views are different presentations of your data. Each base can contain multiple views of the same data with different filters, grouping, and display options.
+
+## View Types
+
+### Table View
+
+Displays data in a table format with columns and rows.
+
+```yaml
+views:
+ - type: table
+ name: "Active Tasks"
+ limit: 10 # Optional: limit results
+ order:
+ - file.name
+ - status
+ - priority
+ groupBy:
+ property: status
+ direction: ASC
+ filters:
+ and:
+ - 'status != "done"'
+ summaries:
+ priority: Average
+```
+
+**Table Features:**
+
+- Column ordering with `order`
+- Row grouping with `groupBy`
+- Row limits with `limit`
+- Summary rows with `summaries`
+- Sortable columns
+- Filterable by column values
+
+### Card View
+
+Displays each item as a visual card.
+
+```yaml
+views:
+ - type: cards
+ name: "Library"
+ order:
+ - cover
+ - file.name
+ - author
+ - status
+ filters:
+ not:
+ - 'status == "dropped"'
+```
+
+**Card Features:**
+
+- Visual preview of properties
+- Customizable field display order
+- Grouped layout
+- Good for image-heavy content
+
+### List View
+
+Simple list of matching items with key properties.
+
+```yaml
+views:
+ - type: list
+ name: "Quick List"
+ order:
+ - file.name
+ - status
+```
+
+**List Features:**
+
+- Compact display
+- Quick scanning
+- Title-focused
+- Ideal for large datasets
+
+### Map View
+
+Displays items with geographic coordinates (requires location properties).
+
+```yaml
+views:
+ - type: map
+ name: "Locations"
+ latitude: latitude_property
+ longitude: longitude_property
+```
+
+**Map Features:**
+
+- Geographic visualization
+- Clustering
+- Interactive pan/zoom
+- Requires location data in frontmatter
+
+## View Properties
+
+All views support these common properties:
+
+| Property | Required | Description |
+| ----------- | -------- | ----------------------------------------------- |
+| `type` | Yes | View type: `table`, `cards`, `list`, or `map` |
+| `name` | Yes | Display name for the view |
+| `order` | No | Array of properties to display in order |
+| `filters` | No | View-specific filters (in addition to global) |
+| `groupBy` | No | Group results by property (table views) |
+| `limit` | No | Maximum number of items to display |
+| `summaries` | No | Aggregation functions for columns (table views) |
+
+## View Ordering
+
+The `order` property controls which columns/fields display and in what sequence:
+
+```yaml
+order:
+ - file.name
+ - status
+ - formula.priority_label
+ - due
+ - formula.days_until_due
+```
+
+Use property names (from frontmatter), file properties (`file.name`, `file.mtime`), or formulas (`formula.formula_name`).
+
+## View Grouping
+
+Group results by a property using `groupBy`:
+
+```yaml
+groupBy:
+ property: status
+ direction: ASC
+```
+
+- `property`: Which property to group by
+- `direction`: `ASC` (ascending) or `DESC` (descending)
+
+## View Limits
+
+Limit the number of items displayed:
+
+```yaml
+limit: 50 # Show only first 50 items
+```
+
+Useful for views of large datasets or "recent items" views.
+
+## View Summaries
+
+Add aggregation rows to table views:
+
+```yaml
+summaries:
+ priority: Average
+ completed_date: Latest
+ tasks_count: Sum
+```
+
+Available aggregation functions: `Sum`, `Count`, `Average`, `Min`, `Max`, `Median`, `Stddev`, `Earliest`, `Latest`, `Range`, `Checked`, `Unchecked`, `Empty`, `Filled`, `Unique`
+
+See [Functions Reference](functions-reference.md) for details.

# Obsidian Flavored Markdown Skill
-This skill enables skills-compatible agents to create and edit valid Obsidian Flavored Markdown, including all Obsidian-specific syntax extensions.
+This skill enables agents to create and edit valid Obsidian Flavored Markdown, including all Obsidian-specific syntax extensions.
## Overview
-Obsidian uses a combination of Markdown flavors:
-- [CommonMark](https://commonmark.org/)
-- [GitHub Flavored Markdown](https://github.github.com/gfm/)
-- [LaTeX](https://www.latex-project.org/) for math
-- Obsidian-specific extensions (wikilinks, callouts, embeds, etc.)
+Obsidian uses a combination of standard and extended Markdown flavors:
-## Basic Formatting
+- [CommonMark](https://commonmark.org/) - Standard Markdown
+- [GitHub Flavored Markdown](https://github.github.com/gfm/) - GFM extensions
+- [LaTeX](https://www.latex-project.org/) - Math notation
+- **Obsidian extensions** - Wikilinks, callouts, embeds, properties, and more
-### Paragraphs and Line Breaks
+## Basic Formatting
-```markdown
-This is a paragraph.
+### Text Styles
-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.
-```
+| Style | Syntax | Example |
+| ------------- | ------------------------ | --------------- |
+| Bold | `**text**` or `__text__` | **Bold** |
+| Italic | `*text*` or `_text_` | _Italic_ |
+| Bold + Italic | `***text***` | **_Both_** |
+| Strikethrough | `~~text~~` | ~~Striked~~ |
+| Highlight | `==text==` | ==Highlighted== |
+| Inline code | `` `code` `` | `code` |
### Headings
```markdown
# Heading 1
+
## Heading 2
+
### Heading 3
+
#### Heading 4
+
##### Heading 5
+
###### Heading 6
```
-### Text Formatting
-
-| Style | Syntax | Example | Output |
-|-------|--------|---------|--------|
-| Bold | `**text**` or `__text__` | `**Bold**` | **Bold** |
-| Italic | `*text*` or `_text_` | `*Italic*` | *Italic* |
-| Bold + Italic | `***text***` | `***Both***` | ***Both*** |
-| Strikethrough | `~~text~~` | `~~Striked~~` | ~~Striked~~ |
-| Highlight | `==text==` | `==Highlighted==` | ==Highlighted== |
-| Inline code | `` `code` `` | `` `code` `` | `code` |
-
-### Escaping Formatting
+### Escaping
Use backslash to escape special characters:
+
```markdown
\*This won't be italic\*
\#This won't be a heading
1\. This won't be a list item
```
-Common characters to escape: `\*`, `\_`, `\#`, `` \` ``, `\|`, `\~`
-
-## Internal Links (Wikilinks)
+## Wikilinks
-### Basic Links
+Obsidian-specific links to other notes creating bidirectional relationships.
```markdown
[[Note Name]]
-[[Note Name.md]]
[[Note Name|Display Text]]
-```
-
-### Link to Headings
-
-```markdown
[[Note Name#Heading]]
-[[Note Name#Heading|Custom Text]]
-[[#Heading in same note]]
-[[##Search all headings in vault]]
-```
-
-### Link to Blocks
-
-```markdown
[[Note Name#^block-id]]
-[[Note Name#^block-id|Custom Text]]
-```
-
-Define a block ID by adding `^block-id` at the end of a paragraph:
-```markdown
-This is a paragraph that can be linked to. ^my-block-id
-```
-
-For lists and quotes, add the block ID on a separate line:
-```markdown
-> This is a quote
-> With multiple lines
-
-^quote-id
-```
-
-### Search Links
-
-```markdown
-[[##heading]] Search for headings containing "heading"
-[[^^block]] Search for blocks containing "block"
+[[#Heading in same note]]
```
-## Markdown-Style Links
+Wikilinks automatically appear in backlinks and the Graph view.
-```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)
-```
-
-Note: Spaces must be URL-encoded as `%20` in Markdown links.
+See [Wikilinks](wikilinks.md) for complete documentation.
