Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.01529 |
| Opus 5.5 | $0.00018 | $0.00612 |
| Sonnet 5.5 | $0.00009 | $0.00306 |
| Haiku 4.5 | $0.00004 | $0.00153 |
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 1mo 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.
How it starts
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
Recommended structure for an agent/task app
Command
Home
Active Runs
Queue
Build
Projects
Skills
Prompts
Files
Memory
Notes

Width guidance
macOS: 220–280 px
iPad: 240–320 px
Compact iPhone: collapse into NavigationStack or tab-based root
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.

apple-hig-sidebars is a skill published in the GitHub repository aka-kika/akakika-skills (11 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 1,529 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
