Error message

No changes

What it means

Thrown by `GlobalConfig::edit_rag_docs` in src/config/mod.rs:1402 after the user edits the temporary document-list file, when the resulting `new_document_paths` list is empty or identical to the existing `document_paths`. The library refuses to refresh the RAG index because there is nothing to change, treating a no-op edit as an error so callers don't silently re-embed unchanged data.

Solutions

1. Add, remove, or modify at least one document path in the temp file before saving
2. If inspection was the goal, exit the editor without saving (or abort the command)
3. Programmatically pass a genuinely different document list to `rag.refresh_document_paths` instead of relying on the editor flow

Example fix

// before (unchanged list triggers the error)
rag.refresh_document_paths(&document_paths, false, config, signal).await?;
// after: verify the change first
if new_paths.is_empty() || new_paths == old_paths {
    return Ok(()); // treat as no-op instead of erroring
}
rag.refresh_document_paths(&new_paths, false, config, signal).await?;

let new_paths: Vec<String> = read_edited_list();
if new_paths.is_empty() || new_paths == old_paths {
    eprintln!("No changes made to the document list; nothing to refresh");
    return Ok(());
}

if let Err(e) = config.edit_rag_docs(signal).await {
    if e.to_string() == "No changes" {
        return Ok(()); // treat as benign no-op
    }
    return Err(e.into());
}

When it happens

Trigger: Opening the temp file in the editor and saving without modifications; deleting every line before saving; an editor wrapper that writes the same content back (e.g. format-on-save producing identical paths).

Common situations: Users who open the doc-list just to inspect it and save; editors or scripts that touch the file without changing content; accidentally clearing the file.
