At a glance

Implement UIKit navigation, Auto Layout, and Apple Human Interface Guidelines in iOS.

  • SKILL.md covers Priority: P0 (CRITICAL), Implementation Guidelines, Anti-Patterns and References, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Auto Layout constraints

What it does

iOS UI Navigation is an agent skill from HoangNguyen0403/agent-skills-standard. Implement UIKit navigation, Auto Layout, and Apple Human Interface Guidelines in iOS. Use when implementing UIKit navigation, Auto Layout constraints, or HIG compliance.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Mobile, covering iOS development. It works with iOS. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Implementing UIKit navigation
  • Auto Layout constraints

Example prompts

  • “/ios-ui-navigation”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

iOS UI Navigation loads about 516 tokens when it runs, and up to ~958 if it reads all its reference files. Until then it costs about 47 tokens; SKILL.md has 172 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~516
With references · SKILL.md plus every file in references/, read only if the agent opens them
~958

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

iOS UI & Layout Standards

Priority: P0 (CRITICAL)

Implementation Guidelines

Auto Layout
  • Code-Based Layout: Prefer programmatic layout using NSLayoutAnchor or SnapKit over Storyboards for better source control.
  • Safe Area: Always respect view.safeAreaLayoutGuide.
  • UIStackView: Use for linear layouts to reduce constraint complexity.
UIKit Best Practices
  • View Lifecycle: Perform layout adjustments in viewWillLayoutSubviews or updateConstraints.
  • Reusable Views: Extract complex UI into custom UIView subclasses.
  • Image Optimization: Use SF Symbols for icons. Preferred vector (PDF/SVG) for custom assets.
  • SwiftUI Bridge: Use UIViewRepresentable or UIViewControllerRepresentable to host UIKit in SwiftUI.
Human Interface Guidelines (HIG)
  • Accessibility: Support Dynamic Type and provide meaningful accessibilityLabel.
  • Feedback: Use UINotificationFeedbackGenerator for haptic feedback on actions.
  • Margins: Follow standard system margins (typically 16-20pt).

Anti-Patterns

  • No CGRect(x:y:w:h): Use Auto Layout.
  • No complex constraint logic in VC: Use UIStackView or custom views.
  • No Blank Screens: Use skeleton views or UIActivityIndicatorView.
