Claudian — AI skill for Claude Code

Claudian

  


An Obsidian plugin that embeds AI coding agents (Claude Code, Codex, and more to come) in your vault. Your vault becomes the agent's working directory — file read/write, search, bash, and multi-step workflows all work out of the box.

Features & Usage

Open the chat sidebar from the ribbon icon or command palette. Select text and use the hotkey for inline edit. Everything works like Claude Code or Codex — talk to the agent, and it reads, writes, edits, and searches files in your vault.

**Inline Edit** — Select text or start at the cursor position + hotkey to edit directly in notes with word-level diff preview.

**Slash Commands & Skills** — Type `/` or `$` for reusable prompt templates or Skills from user- and vault-level scopes.

**`@mention`** - Type `@` to mention anything you want the agent to work with, vault files, subagents, MCP servers, or files in external directories.

**Plan Mode** — Toggle via `Shift+Tab`. The agent explores and designs before implementing, then presents a plan for approval.

**Instruction Mode (`#`)** — Refined custom instructions added from the chat input.

**MCP Servers** — Connect external tools via Model Context Protocol (stdio, SSE, HTTP). Claude manages vault MCP in-app; Codex uses its own CLI-managed MCP configuration.

**Multi-Tab & Conversations** — Multiple chat tabs, conversation history, fork, resume, and compact.

Requirements
