# napkin

CLI for Obsidian vaults. Operates directly on markdown files — no Obsidian app, no Electron, no Catalyst license.

Install: `npm install -g napkin-ai`

## Vault Structure

`.napkin/` is the vault root — all content lives inside it:

```
my-project/
  .napkin/                  # The vault
    NAPKIN.md               # Context note (Level 0)
    config.json             # Unified config (syncs to .obsidian/)
    decisions/              # Template-defined directories
    architecture/
    Templates/              # Note templates
    .obsidian/              # Obsidian compatibility (auto-generated)
  src/                      # Project source (not in vault)
```

## Progressive Disclosure

napkin reveals information gradually — overview first, then search, then read:

| Level | Command | What it does |
|-------|---------|-------------|
| L0 | `NAPKIN.md` | Project context note |
| L1 | `napkin overview` | L0 + vault map with TF-IDF keywords per folder |
| L2 | `napkin search <query>` | BM25 + backlinks + recency ranked results with snippets |
| L3 | `napkin read <file>` | Full file content |

**Workflow: overview → search → read**

## Initialize

```bash
napkin init                              # Initialize empty vault
napkin init --template coding            # Scaffold with template
napkin init --template company           # people/, projects/, runbooks/, infrastructure/
napkin init --template product           # features/, roadmap/, research/, specs/, releases/
napkin init --template personal          # people/, projects/, areas/, references/
napkin init --template research          # papers/, concepts/, questions/, experiments/
napkin init --list                       # List available templates
napkin init --path /some/dir             # Initialize in specific directory
```

Each template includes directory structure, `_about.md` files, Obsidian note templates, and a `NAPKIN.md` skeleton.

## Overview & Graph

```bash
napkin overview                          # Vault map with TF-IDF keywords per folder
napkin overview --depth 3                # Limit folder depth
napkin overview --keywords 5             # Max keywords per folder
napkin graph                             # Interactive force-directed vault graph
```

## Config

```bash
napkin config show                       # Show full config
napkin config get --key search.limit     # Get a value
napkin config set --key search.limit --value 50
```

## Syntax

napkin uses standard CLI flags. Quote values with spaces:

```bash
napkin create --name "My Note" --content "Hello world"
```

### Global flags

| Flag | Description |
|------|-------------|
| `--json` | Output as JSON (use this for programmatic access) |
| `-q, --quiet` | Suppress output |
| `--vault <path>` | Vault path (default: auto-detect by walking up from cwd looking for `.napkin/`) |
| `--copy` | Copy output to clipboard |

### File targeting

- `--file <name>` — resolves like a wikilink (name only, no path or extension needed)
- `--path <path>` — exact path from vault root, e.g. `Projects/note.md`

## Commands

### Vault

```bash
napkin vault                                # Vault info (name, path, files, folders, size)
napkin version                              # CLI version
```

### Files & folders — `napkin file`

```bash
napkin file info <name>                     # File info (path, size, dates)
napkin file list                            # List all files
napkin file list --ext md                   # Filter by extension
napkin file list --folder Projects          # Filter by folder
napkin file list --total                    # Count files
napkin file folder <path>                   # Folder info (files, folders, size)
napkin file folder <path> --info files      # Just the file count
napkin file folders                         # List all folders
napkin file folders --total                 # Count folders
```

### Read & write

```bash
napkin read <file>                          # Read file contents
napkin create --name "Note" --content "# Hello"
napkin create --name "Note" --path "Projects" --template "Meeting Note"
napkin append --file "Note" --content "New line at end"
napkin prepend --file "Note" --content "New line after frontmatter"
napkin move --file "Note" --to Archive
napkin rename --file "Note" --name "Renamed Note"
napkin delete --file "Note"                 # Move to .trash
napkin delete --file "Note" --permanent     # Delete permanently
```

### Daily notes — `napkin daily`

Reads config from `.napkin/.obsidian/daily-notes.json` (folder, format, template).

```bash
napkin daily today                          # Create today's daily note (from template if configured)
napkin daily path                           # Print daily note path
napkin daily read                           # Print daily note contents
napkin daily append --content "- [ ] Buy groceries"
napkin daily prepend --content "## Morning"
```

### Search

Ranked search using BM25 + backlinks + recency. Returns snippets with context by default.

```bash
napkin search "meeting"                     # Find files matching text
napkin search --query "meeting"             # Same, using flag
napkin search "TODO" --path Projects        # Limit to folder
napkin search "bug" --total                 # Count matches
napkin search "deploy" --limit 5            # Top 5 results
napkin search "TODO" --no-snippets          # Files only, no snippets
napkin search "deploy" --snippet-lines 3    # Context lines around matches
napkin search "auth" --score               # Include relevance score
```

### Tasks — `napkin task`

napkin task list --done                     # Completed only
napkin task list --daily                    # Today's daily note tasks
napkin task list --file "Project A"         # Tasks in specific file
napkin task list --verbose                  # Group by file with line numbers
napkin task list --total                    # Count tasks
napkin task show --file "note" --line 3     # Show task info
napkin task show --file "note" --line 3 --toggle  # Toggle ✓/○

napkin bookmark add --folder "Projects"     # Bookmark a folder
napkin bookmark add --search "TODO"         # Bookmark a search
napkin bookmark add --url "https://example.com" --title "Example"
```

### Bases — `napkin base`

Query vault files using Obsidian Bases `.base` files (YAML-defined filters over frontmatter properties, powered by SQLite in-memory).

```bash
napkin base list                            # List .base files
napkin base views --file "projects"         # List views in a base
napkin base query --file "projects"         # Query default view
napkin base query --file "projects" --view "Active"  # Query named view
napkin base query --file "projects" --format paths   # Just file paths
napkin base query --file "projects" --format csv     # CSV output
napkin base create --file "projects" --name "New Item"  # Create item in base
```

### Canvas — `napkin canvas`

Read and write JSON Canvas files (`.canvas`) — nodes, edges, groups.

```bash
napkin canvas list                          # List .canvas files
napkin canvas list --total                  # Count canvases
napkin canvas read --file "Board"           # Dump canvas (nodes + edges)
napkin canvas nodes --file "Board"          # List all nodes
napkin canvas nodes --file "Board" --type text  # Filter by type
napkin canvas create --file "Board"         # Create empty canvas
napkin canvas create --file "Board" --path "Projects"
napkin canvas add-node --file "Board" --type text --text "# Hello"
napkin canvas add-node --file "Board" --type file --note-file "Notes/note.md"
napkin canvas add-node --file "Board" --type link --url "https://example.com"
napkin canvas add-node --file "Board" --type group --label "My Group"
napkin canvas add-node --file "Board" --type text --text "Positioned" --x 100 --y 200
napkin canvas add-edge --file "Board" --from abc1 --to def2 --label "relates to"
napkin canvas remove-node --file "Board" --id abc1  # Removes node + connected edges
```

Node IDs are 16-char hex. `--from`/`--to`/`--id` accept ID prefixes for convenience.
Node types: `text`, `file`, `link`, `group`. Colors: `1`-`6` or hex.
New nodes auto-position to the right of existing content.

### Word count

```bash
napkin wordcount --file "note"              # Words + characters
napkin wordcount --file "note" --words      # Words only
napkin wordcount --file "note" --characters # Characters only
```

### Agent onboarding

```bash
napkin onboard                              # Print instructions for CLAUDE.md/AGENTS.md
```

## JSON output

Every command supports `--json`. Always use `--json` for programmatic access:

```bash
napkin task list --todo --json
# {"tasks": [{"text": "Buy groceries", "done": false, "file": "Daily/2024-01-15.md", "line": 5}, ...]}

napkin search "deploy" --json
# {"files": ["Projects/Deploy Guide.md", "Notes/CI-CD.md"]}

napkin property read --file "note" --name status --json
# {"value": "done"}
```

## Common workflows

### Morning standup prep

```bash
napkin daily read --json                    # What did I write yesterday?
napkin task list --todo --json              # What's pending?
napkin search "blocker" --json              # Any blockers?
```

### Project overview

```bash
napkin file list --folder Projects --json   # List project files
napkin tag list --counts --json             # Tag distribution
napkin link orphans --json                  # Forgotten files
napkin link unresolved --json               # Broken links to fix
```

### Note management

```bash
napkin create --name "Meeting Notes" --template "Meeting Note" --path "Meetings"
napkin property set --file "Meeting Notes" --name attendees --value "Alice, Bob"
napkin append --file "Meeting Notes" --content "- [ ] Follow up on deployment"
```

# JSON Canvas Reference

Canvas files (`.canvas`) are JSON following the [JSON Canvas Spec 1.0](https://jsoncanvas.org/spec/1.0/).

```json
{
