# Wikilink Types

An [Obsidian](https://obsidian.md) plugin that adds typed relationships to wikilinks. Type `@` inside a wikilink alias to trigger an autocomplete dropdown of relationship types. On selection, the plugin syncs the relationship to YAML frontmatter automatically — so Dataview, Graph Link Types, Breadcrumbs, and the rest of the ecosystem can consume it without changes.

## How It Works

Type `@` inside a wikilink alias to trigger the autocomplete — either after a space or right after the `|`. You can use one or multiple relationship types in natural display text:

```
[[Analysis|The new research @supersedes and @contradicts the previous analysis]]
```

On save, each `@type` that matches a configured relationship type is synced to YAML frontmatter:

```yaml
---
supersedes:
  - "[[Analysis]]"
contradicts:
  - "[[Analysis]]"
---
```

You never touch YAML. The `@` syntax is the authoring interface. The YAML is the storage and compatibility layer. The frontmatter is the authoritative source for all programmatic and AI uses.

### Rules

- `@type` must be preceded by a **space** or appear at the **start of the alias** (right after `|`) — `john@causes.com` is ignored, `text @causes` and `[[Note|@causes]]` both match
- Only configured relationship types generate frontmatter — `@monkeyballs` in display text is just text
- Multiple `@types` per wikilink are supported — each creates its own frontmatter entry
- `@` in display text that doesn't match a configured type is left alone for human readability

### Authoring Flow

1. Type `[[Note Name|Your display text @` — the autocomplete dropdown appears
2. Select a relationship type (or keep typing to filter)
3. Continue writing display text, or add another `@type`
4. Close the link with `]]`
5. On save, the plugin syncs matched types to YAML frontmatter

## Installation

### Community Plugins

1. Open **Settings → Community Plugins → Browse**
2. Search for **Wikilink Types**
3. Click **Install**, then **Enable**

### BRAT

To test pre-release versions, install via [BRAT](https://github.com/TfTHacker/obsidian42-brat):

1. Install BRAT from Community Plugins
2. Open Command Palette → **BRAT: Add a beta plugin for testing**
3. Paste: `penfieldlabs/obsidian-wikilink-types`
4. Click **Add Plugin**, then enable in **Settings → Community Plugins**

### Manual

1. Download `main.js`, `manifest.json`, and `styles.css` from the [latest release](https://github.com/penfieldlabs/obsidian-wikilink-types/releases)
2. Create a `wikilink-types` folder in your vault's `.obsidian/plugins/` directory
3. Copy the three files into that folder
4. Enable the plugin in **Settings → Community Plugins**

> **Tip:** Use **Settings → Community Plugins → 📁** (Open plugins folder) to open the plugins directory.

## Configuration

Relationship types are stored in `data.json` inside the plugin directory (`.obsidian/plugins/wikilink-types/data.json`). On first run, the plugin writes a default set of 24 types. Edit the JSON directly to add, remove, rename, or reorder types.

Each entry has three fields:

```json
{
  "key": "supersedes",
  "label": "Supersedes",
  "description": "This replaces an outdated understanding"
}
```

- **key** — written to the wikilink and used as the YAML frontmatter field name
- **label** — displayed in the autocomplete dropdown
- **description** — shown below the label in the dropdown

## Compatibility

| Plugin | Works? | How |
|---|---|---|
| Dataview | Yes | Reads YAML frontmatter natively |
| Graph Link Types | Yes | Reads frontmatter via Dataview |
| Breadcrumbs | Yes | Reads frontmatter |
| Juggl | Yes | Reads Dataview metadata |
| Templater | Yes | No conflicts |
| Excalidraw | Yes | No conflicts |

## Graceful Degradation

If you uninstall the plugin:

- YAML frontmatter remains — **no data loss**
- `@type` text stays visible in wikilink aliases — readable, just not styled
- All Dataview queries continue to work
- Graph Link Types continues to work

## Content Ingestion

[PENgram](https://github.com/penfieldlabs/pengram) extracts structured notes from 
YouTube videos, documents, and other content sources — ready for relationship 
discovery by the Vault Linker. PENgram handles ingestion; Wikilink Types handles 
the connections.

## AI-Assisted Relationship Discovery

The [Vault Linker](skill/SKILL.md) skill lets AI agents (Claude Code, OpenClaw, etc.) analyze your vault and discover relationships between notes. The agent reads your notes, identifies connections you might have missed, and writes them in the Wikilink Types format — with your approval.

See [`skill/SKILL.md`](skill/SKILL.md) for the full skill specification.

For autonomous/overnight linking of entire vaults, see the [build](prompts/autonomous-vault-linking.md) and [verify](prompts/verify-and-repair.md) prompts.
