Claudian

An Obsidian plugin that embeds Claude Code as an AI collaborator in your vault. Your vault becomes Claude's working directory, giving it full agentic capabilities: file read/write, search, bash commands, and multi-step workflows.

Features

• Full Agentic Capabilities: Leverage Claude Code's power to read, write, and edit files, search, and execute bash commands, all within your Obsidian vault.
• Context-Aware: Automatically attach the focused note, mention files with @, exclude notes by tag, include editor selection (Highlight), and access external directories for additional context.
• Vision Support: Analyze images by sending them via drag-and-drop, paste, or file path.
• Inline Edit: Edit selected text or insert content at cursor position directly in notes with word-level diff preview and read-only tool access for context.
• Instruction Mode (#): Add refined custom instructions to your system prompt directly from the chat input, with review/edit in a modal.
• Slash Commands: Create reusable prompt templates triggered by /command, with argument placeholders, @file references, and optional inline bash substitutions.
• Skills: Extend Claudian with reusable capability modules that are automatically invoked based on context, compatible with Claude Code's skill format.
• Custom Agents: Define custom subagents that Claude can invoke, with support for tool restrictions and model overrides.
• Claude Code Plugins: Enable Claude Code plugins installed via the CLI, with automatic discovery from ~/.claude/plugins and per-vault configuration. Plugin skills, agents, and slash commands integrate seamlessly.
• MCP Support: Connect external tools and data sources via Model Context Protocol servers (stdio, SSE, HTTP) with context-saving mode and @-mention activation.
• Advanced Model Control: Select between Haiku, Sonnet, and Opus, configure custom models via environment variables, fine-tune thinking budget, and enable Sonnet with 1M context window (requires Max subscription).
• Plan Mode: Toggle plan mode via Shift+Tab in the chat input. Claudian explores and designs before implementing, presenting a plan for approval with options to approve in a new session, continue in the current session, or provide feedback.
• Security: Permission modes (YOLO/Safe/Plan), safety blocklist, and vault confinement with symlink-safe checks.
• Claude in Chrome: Allow Claude to interact with Chrome through the claude-in-chrome extension.
