Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shadcn_ui-menubar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Shadcn UI — Menubar

Instructions

ShadMenubar is a visually persistent menu (e.g. File, Edit, View). Each top-level entry is a ShadMenubarItem with child (label) and items (list of menu entries). Use ShadContextMenuItem and ShadContextMenuItem.inset for entries; use ShadSeparator.horizontal or Divider(height: 8) for dividers. Nest ShadContextMenuItem with items for submenus; use trailing: Icon(LucideIcons.chevronRight) on parent. Set enabled: false to disable an item.

          enabled: false,
