✅ Validated

VALID BUG - Confirmed in source code

Component Location: src/cortex-tui/src/modal/mcp_manager/handlers.rs

Bug Verification: The code at lines 193-203 confirms the reported issue exactly:

KeyCode::Enter => {
    if !name.is_empty() && !command.is_empty() {
        let args_vec: Vec<String> =
            args.split_whitespace().map(|s| s.to_string()).collect();
        return ModalResult::Action(ModalAction::AddMcpServer {
            name: name.clone(),
            command: command.clone(),
            args: args_vec,
        });
    }
    ModalResult::Continue  // <-- BUG: Silent failure with no feedback
}

Issue: When the user presses Enter with empty Name or Command fields, the condition fails and the code returns ModalResult::Continue without any error message, toast, or visual indication of what went wrong. The form simply stays open with no feedback.

Screenshot Evidence: The video clearly demonstrates this behavior - the user attempts to submit the form with an empty Name field and nothing happens.

Duplicate Check: Issue #40685 is about missing required field INDICATORS (visual markers), which is a different bug. This issue is about the silent submission failure behavior - they require different fixes.

Impact: This is a real UX bug that causes user confusion - users don't know why their form submission isn't working.

我来认领！

实现说明:

• 当 Name 或 Command 字段为空时按 Enter，显示红色错误信息
• 用户开始输入时自动清除错误信息
• 按 Tab 切换字段时也会清除错误
