Invalid skill destination: {}

Error message

Invalid skill destination: {}

What it means

Thrown by replace_dest_with_copy when dest.parent() returns None, i.e. the computed destination path is a filesystem root with no parent component. This is a defensive assertion: dest is always app_dir.join(directory), so reaching it requires the app skills directory to have degenerated to a root-level path.

Solutions

1. Print/log dest.display() from the error and check what the app skills directory resolved to
2. Fix the app skills directory setting back to a normal absolute directory (e.g. ~/.claude/skills)
3. If it reproduces with valid settings, file a bug against get_distinct_app_skills_dir path handling

// Rust caller — sanity-check the app skills dir setting before sync
let app_dir = SkillService::get_distinct_app_skills_dir(&ssot, &app)?;
if app_dir.parent().is_none() || app_dir == Path::new("/") {
    return Err(anyhow!("app skills dir misconfigured: {}", app_dir.display()));
}

When it happens

Trigger: A custom/misconfigured app skills directory that resolves to "/" or an empty path, making dest a root path. Not reachable through normal configuration where app_dir is a normal absolute directory.

Common situations: Manually edited settings pointing the app skills dir at a filesystem root; a path-resolution regression in get_distinct_app_skills_dir. Practically never seen in the wild.
