## What it does

\`librarian` sits on top of the Librarian MCP tools and turns a folder of notes into something you can query. It picks up files from `docs/solutions/`, converts PDF, DOCX, spreadsheets, slides and images into markdown, then adds `[[wikilinks]]` to notes that already exist in the vault. Connectors cover Gmail threads, web pages, X/Twitter threads and calendar events.

The subcommands are `ingest`, `import`, `from`, `search`, `connect`, `daily`, `graph`, `analyze`, `daydream` and `status`. `search` digs for prior art, `connect` fills in missing links, `analyze` produces a report on the graph, `daydream` looks for connections you did not spot. Run it with no arguments and it prints the command list.

Two things have to be in place first. The Librarian MCP server must be configured and running — the skill checks it with `library_stats` and, if that call fails, asks you to run `librarian-mcp --setup /path/to/vault` and restart Claude. The `import` command also needs MarkItDown installed via `pip install markitdown`; without it the conversion stops there rather than falling back to something else.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ngmeyer/librarian-mcp --skill skill -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/skill/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/skill/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ngmeyer/librarian-mcp --skill skill -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/skill/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ngmeyer/librarian-mcp --skill skill -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/skill/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ngmeyer/librarian-mcp skill
```

2. **Manually: put the files in place**
- File: `.github/skills/skill/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ngmeyer/librarian-mcp --skill skill -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ngmeyer/librarian-mcp --path skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/skill/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ngmeyer/librarian-mcp --skill skill -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/ngmeyer/librarian-mcp/tree/HEAD/skill/SKILL.md

## When to use it
- move a bug write-up from `docs/solutions/` into the shared vault
- find how a similar problem was solved before
- turn a PDF or DOCX into markdown with links already in place
- keep an important email thread as a structured note
- append today's takeaway to the daily note

## Example prompts
- Ingest the newest file from `docs/solutions/` into the vault
- Search the vault for how I fixed the HMR timeout before
- Import `quarterly-report.pdf` into my notes

# /librarian

Orchestrate high-level knowledge workflows using Librarian MCP tools.

## Prerequisites

Librarian MCP server must be configured and running. Verify by checking that `library_stats` responds. If it fails, tell the user to run `librarian-mcp --setup /path/to/vault` and restart Claude.

## Commands

```
/librarian ingest [path]           Ingest a solution doc into the vault
/librarian import <file>           Convert local document (PDF, DOCX, image) to vault markdown
/librarian from gmail <query>      Import Gmail threads matching a search into the vault
/librarian from web <url>          Import any web page into the vault as markdown
/librarian from twitter <url>      Import an X/Twitter thread into the vault
/librarian from calendar [query]   Import calendar events/meeting notes into the vault
/librarian from claude [session]   Extract learnings from a Claude Code session into the vault
/librarian search <query>          Deep search vault for prior art
/librarian connect [path]          Find and apply missing wikilinks
/librarian daily [text]            Append a learning to today's daily note
/librarian graph [note]            Explore vault structure or a note's neighborhood
/librarian analyze                 Full vault analysis: god nodes, communities, viz, report
/librarian daydream [focus]        Discover non-obvious connections across vault notes
/librarian status                  Vault health overview
```

If no command is given, show the usage summary above.

## ingest

**Purpose:** Import a `docs/solutions/` file (or any local markdown) into the vault, gaining auto-wikilinks and knowledge graph integration. This is the bridge between per-project documentation (like ce:compound output) and the persistent vault.

### Behavior

1. **Locate the source file:**
   - If `[path]` is provided, use it directly
   - If no path, scan `docs/solutions/` for the most recently modified `.md` file
   - If `docs/solutions/` doesn't exist or is empty, tell the user and stop

2. **Read the source file** using the Read tool (local filesystem)

3. **Determine vault destination:**
   - Parse the source file's YAML frontmatter for `category` (or infer from parent directory name)
   - Map to vault path: `Solutions/<category>/<filename>.md`
   - Categories map directly: `build-errors/` -> `Solutions/build-errors/`, etc.

4. **Write to vault** using `library_write` with the file content
   - `library_write` auto-links mentions of existing vault notes as `[[wikilinks]]`
   - Report what links were auto-added

5. **Run `library_suggest_links`** on the newly written file
