Your AI coding agent, such as Claude Code, can work on your team's shared notes the same way it works on any other files: it edits the files on your disk. Relay then carries those edits to everyone else. That works even while notes are closed and while teammates are editing, as long as Obsidian is running.
Your files need to be in a Shared Folder.
Agents also work with Relay versions before 0.8.12, but edits saved outside Obsidian were more likely to need resolving by hand.
For setup, install Relay, share a folder, and invite your collaborators.
Before a broad rewrite, back up the notes you want to preserve.
Give your agent the path to the note and describe the change you want. The agent reads and edits the file, then saves it to disk. Relay picks up the saved file, merges it with your teammates' edits, and syncs the result.
Your teammates can keep editing while the agent works, and the saved changes appear in the shared note. Relay combines saved changes, but it doesn't judge whether they make sense together. Review the combined result when both change the same passage.
The agent can edit local files while Obsidian is closed, but those changes aren't shared until you reopen it. Relay normally reconciles them automatically; rare local conflicts can occur when the same lines were changed in different ways.
For details, see how devices exchange saved changes and how Relay brings edits together.
