Work with Obsidian vaults

obsidian is an agent skill from the OpenClaw project, listed on skills.sh. It lets an agent work in your Obsidian vault with Obsidian's own command-line interface: read, search, create and edit notes, tasks, links, properties and plugins. Since vaults are plain Markdown files, it also allows editing the files directly when that is safer or faster. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
