• Deletes pages or sources after you approve

  Lists exactly which documents a path or pattern matches, asks you to approve, then removes them from the workspace, including the files on disk.

The source says it cannot be undone.

Watch out for

• It can delete files from your workspace

  The delete tool removes pages or sources, including by pattern, from the folder you point it at. It shows the exact list and asks you to confirm, and clients without confirmation support only get the preview. github.com

• Claude writes Markdown files in your folder

  The create, edit and append tools write files under the wiki folder, and an index is kept in .llmwiki. Keep the folder in git or backed up. github.com

• Highlights and comments live only in the index

  The README says highlights, comments, replies and clip data are stored only in .llmwiki/index.db, so back it up and do not delete it. github.com

• A scheduled Claude routine runs on Anthropic's cloud

  The README suggests a nightly Claude Routine to update the wiki. That is optional and separate from the local server. github.com
