// technical analysis

Claudian is an Obsidian plugin designed to integrate AI coding agents directly into a user's vault, effectively turning the vault into an active working directory for agents like Claude Code and Codex. By leveraging a provider-neutral architecture, the plugin enables seamless file manipulation, search, and multi-step workflows within the Obsidian environment. This design choice allows users to maintain their knowledge base while utilizing powerful AI tools for automated editing and planning, though it requires external CLI dependencies to function.

Slash commands and @mentions enable users to quickly trigger reusable prompt templates or reference specific files, subagents, and MCP servers.

Plan Mode provides a structured workflow where the agent designs and proposes changes for user approval before execution.

Support for Model Context Protocol (MCP) allows users to connect external tools and services directly into the Obsidian vault environment.

Multi-tab conversation management supports complex workflows with features like history tracking, forking, and session resuming.

The plugin maintains a provider-neutral core, allowing for flexible integration of different AI agents like Claude and Codex.

// use cases

Inline code editing with word-level diff previews directly within notes.

Planning mode that allows agents to design and propose workflows before implementation.

Integration of external tools and data sources via Model Context Protocol (MCP) servers.

// getting started

To begin, ensure you have the Claude Code CLI or Codex CLI installed on your desktop machine, as these are required for the agent functionality. You can install the plugin by downloading the release files into your vault's plugins folder or by using the BRAT plugin for automatic updates. Once installed, enable 'Claudian' in your Obsidian community plugin settings and configure your CLI paths if the plugin fails to auto-detect them.
