What it does

UI Review is an agent skill from gustavscirulis/snapgrid. Review SwiftUI code for iOS/watchOS Human Interface Guidelines compliance, font usage, Dynamic Type support, and accessibility. Use when user mentions UI review, HIG, accessibility audit, font checks, or wants to verify interface design against Apple standards.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `accessibility-quick-ref.md`, `font-guidelines.md` and `hig-checklist.md`).

It sits in Frontend & Design, covering Accessibility, iOS development and API design. It works with iOS and SwiftUI. The repository describes itself as: SnapGrid is an open-source Mac app for collecting, organizing, and analyzing UI screenshots. It uses AI to automatically detect UI components and patterns, making it a powerful…

When your agent uses it

  • User mentions UI review
  • Accessibility audit
  • Wants to verify interface design against Apple standards

Example prompts

  • “/ui-review”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Identify Files to Review
  2. Load Reference Materials
  3. Review Categories
  4. Common Issues to Flag

What it can do on your machine

Read from SKILL.md and the folder at commit eb7eaf4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch

    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

    Links to these hosts (documentation or services it may open):

    • developer.apple.com

    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

UI Review loads about 1.4k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 455 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 455 words (~1,443 tokens).

“Performs comprehensive UI/UX review of SwiftUI code against Apple's Human Interface Guidelines, font best practices, and accessibility standards for iOS and watchOS.”
