obsidian-agent-cli 0.1.0

Full-featured CLI for Obsidian — manage notes, canvases, Excalidraw, Kanban, periodic notes, git, tasks, and more.

obsidian-agent-cli

A full-featured command-line interface for Obsidian — manage your vault, capture knowledge, build canvases, and run plugin commands, all from the terminal or from an AI agent.

Works with any AI coding assistant (Claude Code, Codex, Gemini CLI, etc.) via the included obsidian_skill.md.

How It Works: Vault Structure

The CLI is designed around a clean separation of concerns inside your vault:

MyVault/                        ← your Obsidian vault root
├── .obsidian/
│
├── AI Workspace/               ← the AI agent's dedicated folder (managed by this CLI)
│   ├── registry.json           #   project registry
│   ├── my-project/             #   per-project knowledge
│   │   └── knowledge-log.md
│   └── Teaching Notes/         #   reference notes written by the agent
│
├── Your Notes/                 ← your folders — the AI never touches these
├── Projects/                   ← yours
└── Journal/                    ← yours

The AI only operates inside AI Workspace/. Every note, canvas, log, and registry file it creates lives there. Your own folders are completely untouched unless you explicitly pass their paths to a command.

💡 Recommended setup: Create a dedicated Obsidian vault just for this — don't drop it into an existing vault you already use heavily. A fresh vault keeps things clean. Then AI Workspace/ is one subfolder inside it, and any other top-level folders you create are entirely yours.

The AI Workspace folder name is just the default — rename it to anything you like:

obsidian config set workspace_path "My AI Zone"

Features

Command group	What it does
note	Create, read, update, patch, delete notes — including surgical heading-level edits
search	Full-text search and Dataview DQL queries
active	Read/write the note currently open in Obsidian
periodic	Daily, weekly, monthly notes — read, write, patch, navigate
workspace	AI workspace project registry and knowledge log
canvas	Build and manage Obsidian canvas files from JSON specs
excalidraw	Build Excalidraw diagrams from JSON specs
kanban	Create and manage Kanban boards
vault	Find notes by glob pattern, move/rename files
tags	Rename tags across the entire vault
batch	Bulk frontmatter edits and find-and-replace
export	Bundle notes into a single markdown file
teach	Write reference/teaching notes into the vault
git	Obsidian Git plugin commands
tasks	Tasks plugin — add and list tasks with emoji markers
template	Templater plugin commands
lint	Obsidian Linter commands
quickadd	QuickAdd plugin — open modal or run a choice
refactor	Rename, extract headings, merge notes
mover	Auto Note Mover — check and trigger rules
meta	Metadata Menu — get/set frontmatter fields
core	Core Obsidian UI — palette, graph, settings, splits
uri	Obsidian URI scheme — works without Obsidian open
status	REST API health check
config	View and update CLI configuration
commands	List and run any Obsidian command by ID

All commands output JSON. Every command returns a single JSON object — parse it, pipe it, or feed it to an AI agent.

Dual-mode transport. Commands try the Obsidian REST API first. If Obsidian isn't running, most commands fall back to the vault filesystem directly.

Requirements

• Python 3.10+
• Obsidian desktop app
• Local REST API community plugin (installed and enabled inside Obsidian)

---

Installation

pip install obsidian-agent-cli

Then run the setup wizard:

obsidian config init

You'll be prompted for:

• Your vault path (e.g. /home/yourname/Documents/MyVault)
• Your workspace folder name (default: AI Workspace)
• The REST API URL (default: http://127.0.0.1:27123)
• Your Local REST API key (copy from Obsidian → Settings → Local REST API)

Verify it works

With Obsidian open:

obsidian status

You should see:

{"ok": true, "versions": {"obsidian": "1.x.x"}, "transport": "api"}

Quick Start

# Create a note
obsidian note create "Projects/my-app/arch.md" --content "# Architecture"

# Read it back
obsidian note read "Projects/my-app/arch.md"

# Search across vault
obsidian search simple "authentication"

# Register a project for AI knowledge tracking
obsidian workspace project register my-app

# Log a discovery
obsidian workspace log my-app "Auth uses RS256 JWTs. Token expiry is 15 min."

# Read back everything the agent knows about this project
obsidian workspace recall my-app

# Build a canvas overview
obsidian canvas build "my-app-overview" --spec '{
  "nodes": [
    {"type": "text", "text": "# My App"},
    {"type": "file", "file": "Projects/my-app/arch.md"}
  ],
  "edges": [
    {"from": 0, "to": 1, "label": "documented in", "color": "4"}
  ]
}'

# Sync vault with git
obsidian git sync -m "feat: update project notes"

---

AI Agent Integration

Drop obsidian_skill.md into any project root. Your AI agent (Claude Code, Codex, Gemini CLI, etc.) will automatically:

1. Register new projects on first encounter
2. Recall prior knowledge at the start of every session
3. Log architectural discoveries and decisions as they happen
4. Build visual canvases and write teaching notes when asked

See docs/SKILL_SETUP.md for details.

---

Configuration

Config is stored in ~/.obsidian-cli/config.json. You can edit it with obsidian config:

obsidian config show                              # view current config
obsidian config set vault_path /path/to/vault    # update vault path
obsidian config set workspace_path "MyWorkspace"  # rename workspace folder
obsidian config set api_key YOUR_KEY             # update API key
obsidian config init                             # re-run setup wizard

Plugin Commands

Many command groups require optional Obsidian plugins:

Plugin	Required by
Local REST API	Everything (core dependency)
Dataview	search advanced, note backlinks, note by-tag, note recent, note orphans, note links
Obsidian Git	git commands
Tasks	tasks ui, tasks toggle
Templater	template commands
Linter	lint commands
QuickAdd	quickadd commands
Auto Note Mover	mover commands
Metadata Menu	meta commands
Excalidraw	excalidraw commands
Kanban	kanban archive

Commands that don't require a plugin work directly on the filesystem and don't need Obsidian to be open.
