## What it does

Vault PKM bridges Claude Code with an Obsidian vault to replace flat, per-project text files. Notes stay organized in one place across different coding repositories. Your vault stays consistent across repositories. The plugin packs 20 MCP tools that handle structured note creation with 13 validated frontmatter templates, keyword lookup, YAML filtering, and wikilink navigation.

The package includes three autonomous background agents: explorer, capture, and auditor. They traverse the knowledge graph using breadth-first search and audit broken links or orphan notes. Semantic similarity queries rely on OpenAI embeddings: without an OpenAI API key, discovery falls back to standard keyword search.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install vault-pkm@claude-community
```

## When to use it
- maintain persistent cross-project memory in an Obsidian vault
- discover related notes via wikilink graph traversal and semantic similarity
- scaffold ADRs and devlogs with validated YAML frontmatter templates
- detect broken wikilinks and orphan files across your knowledge base

## Example prompts
- Find my notes about caching strategies and list related documents
- Create a new ADR note for our database migration using vault_write
- Run a link health audit to find broken wikilinks in my vault

# Vault PKM

Give Claude persistent, structured memory across conversations using your Obsidian vault. Read, write, search, and navigate your knowledge base — all from within Claude Code.

Under the hood, this Claude Code plugin provides 20 [MCP](https://modelcontextprotocol.io/) (Model Context Protocol) tools for note creation, semantic search, graph traversal, metadata queries, and session memory — plus agents, hooks, and skills for seamless workflow integration. Published on npm as [`obsidian-pkm`](https://www.npmjs.com/package/obsidian-pkm).

> If you find this useful, please [star the repo](https://github.com/AdrianV101/obsidian-pkm-plugin) — it helps others discover the plugin.

## Why

Claude Code has built-in memory, but it's flat text files scoped to individual projects — no structure, no search beyond exact matches, no connections between notes, and no way to query across projects. As knowledge grows, it doesn't scale. This server replaces that with a proper PKM layer: structured notes with enforced metadata, semantic search, a navigable knowledge graph, and cross-project access through a single Obsidian vault.

- **Structured session memory** — Every tool call is logged with timestamps and session IDs, so Claude can recall exactly what was read, written, and searched in previous conversations — not just what was saved to a text file.
- **Structured knowledge creation** — ADRs, research notes, devlogs, and tasks are created from enforced templates with validated frontmatter — not freeform text dumps. Your vault stays consistent and queryable.
- **Semantic discovery** — "Find my notes about caching strategies" works even if you never used the word "caching." Conceptual search surfaces relevant knowledge that keyword search misses.
- **Graph-aware connections** — Claude explores your knowledge graph by following wikilinks, discovering related notes by proximity rather than just content. Link suggestions help weave new notes into your existing web of knowledge.
- **Knowledge capture** — Decisions, tasks, and research findings are captured by specialized agents in the background without interrupting your coding flow.

Without this, knowledge stays fragmented across per-project memory files and chat logs. With it, your AI assistant maintains a unified knowledge base that compounds over time.

### How It Compares

| | Vault PKM | [remember](https://github.com/Digital-Process-Tools/claude-remember) | Claude built-in memory |
|---|---|---|---|
| **Knowledge base** | Your Obsidian vault (markdown files you own) | Compressed conversation logs (`.remember/` dir) | CLAUDE.md + auto-memory files |
| **Scope** | Cross-project (one vault for everything) | Per-project | Per-project (git-repo scoped) |
| **Semantic search** | OpenAI embeddings | — | — |
