Claudian plugin for Obsidian

Canonical version: 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+.
