# Claudian plugin for Obsidian
Claudian embeds AI coding agents ([[Claude Code]], [[Codex CLI]], Opencode, and others) directly into Obsidian. The vault becomes the agent's working directory — file read/write, search, bash, and multi-step workflows all work out of the box.
Key capabilities:
- Chat sidebar with multi-tab conversations, fork, resume, and compact
- **Inline edit** — select text + hotkey to edit in place with word-level diff preview
- **Slash commands & Skills** — `/` or `
for reusable prompt templates and Skills (user and vault scope)
- **`@mention`** — pull in vault files, subagents, MCP servers, or external files as context
- **Plan mode** (`Shift+Tab`) — agent explores and designs before implementing, then asks for approval
- **Instruction mode (`#`)** — refined custom instructions added from the chat input
- **MCP servers** — connect external tools via [[Model Context Protocol (MCP)]] (stdio, SSE, HTTP)
Requires the Claude Code CLI (and a Claude subscription, [[Anthropic]] API key, or compatible provider like Openrouter / Kimi). Optional providers: Codex CLI, Opencode. Desktop only, Obsidian v1.7.2+.
