apple-hig-sidebars is a skill for Claude Code, Codex from aka-kika/akakika-skills. It costs 44 tokens per session (1,529 once invoked), scanned A, original, MIT.

A design guide for sidebars in Apple-platform apps, including macOS and iPadOS. It treats the sidebar as the place for the app's main sections and navigation.

In plain words
What is it for?
Use it when structuring navigation for areas such as Home, Projects, Tasks, Files, Agents, Skills, Notes, Reports, or Settings, including split views that adapt to narrow screens.

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

apple-hig-sidebars 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 12d 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.

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Apple HIG Sidebars

Design and review the sidebar as the map of the app: top-level navigation only, grouped into calm sections, paired with split navigation, and safe when it collapses on compact widths. Reach for this on macOS, iPadOS, SwiftUI NavigationSplitView, AppKit source lists, UIKit split views, and productivity apps with projects, files, agents, notes, skills, tasks, or dashboards.

Core rule

Sidebar = top-level navigation
Toolbar = current-screen actions
Command palette = fast global commands
Inspector = selected-item details

A sidebar is the map of the app. It is not a dashboard and not a control panel.

Apple-style principles

1. Use sidebars for top-level navigation

Good sidebar items:

  • Home
  • Inbox
  • Projects
  • Tasks
  • Files
  • Agents
  • Skills
  • Notes
  • Reports
  • Settings

Avoid putting these in the sidebar:

  • One-off buttons
  • Deep detail content
  • Destructive actions
  • Dashboard widgets
  • Status timelines
  • Large progress cards
  • Long descriptions

2. Pair the sidebar with split navigation

Preferred SwiftUI structure:

NavigationSplitView {
    SidebarView(selection: $selection)
} content: {
    ContentListView(selection: $selection)
} detail: {
    DetailView(selection: selection)
}

Use two columns for:

Sidebar → Detail

Use three columns for:

Sidebar → List → Detail

Examples:

Projects → Tasks → Task Detail
Folders → Notes → Note Editor
Agents → Runs → Run Detail

3. Keep the sidebar calm

Rules:

  • Short labels
  • Familiar SF Symbols
  • Clear selected state
  • Grouped sections
  • Generous spacing
  • Minimal badges
  • No neon
  • No large cards
  • No heavy gradients

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
