What it is
Claudian is an Obsidian plugin that embeds AI coding agents (Claude Code, Codex, Grok, Opencode, Pi, and more) in your vault. The vault is the agent's working directory, enabling file read/write, search, bash, and multi-step workflows.
How it works
The plugin provides a chat sidebar, inline edit, slash commands/skills, and an @mention mechanism to specify vault files or external directories. It supports Plan Mode for exploration and planning before execution, and Instruction Mode for custom instructions. It includes MCP servers to connect external tools and multiple chat tabs for conversations. It integrates various provider CLIs (Claude Code, Codex, Grok, OpenCode, Pi) and uses a provider registry/runtime to manage interactions.
