Writing & notes
What it does
Brings agent tools - Claude Code, Codex, Gemini CLI - into the Obsidian interface, letting you reference notes with `@notename`, attach images and run saved commands without leaving the vault. Japanese documentation is provided. The agent tool itself must be installed and paid for separately, referenced notes go to that provider, and if you allow write access, back up anything important first.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
