no active repository

Error message

no active repository

What it means

confirm_mention_for_git_diff asks the project for its active git repository via project.active_repository(cx). None means no repository is currently marked active — none of the open worktrees is a git repo, or git detection has not completed/selected one yet — so there is nothing to diff against.

Solutions

1. Open the project at a git repository root (or a subdirectory of one).
2. Wait a moment for git detection to complete, then retry the mention.
3. In multi-repo projects, interact with the source-control panel once so an active repository is selected.
4. Surface 'no git repository in this project' in the editor instead of a generic error.

let has_active_repo = project.read(cx).active_repository(cx).is_some();
if !has_active_repo {
    // hide or disable the git-diff mention suggestion
}

match confirm_task.await {
    Ok(mention) => { /* attach */ }
    Err(err) if err.to_string() == "no active repository" => {
        show_user("Open a project with a git repository to use diff mentions")
    }
    Err(err) => return Err(err),
}

When it happens

Trigger: Using a git-diff mention (diff against a base ref) in a folder that is not a git repository; right after opening a project before git status detection finishes; a multi-worktree project where no active repository has been set.

Common situations: Plain folders without .git; freshly opened clones before detection completes; remote projects with pending repo detection; worktrees whose .git link is broken so no repo registers.
