Swiftui Pro

What it does

When your agent uses it

• Reviewing SwiftUI projects
• Tasks that involve iOS development

Example prompts

• “/swiftui-pro”

Workflow steps

11 steps, taken from the first numbered list in SKILL.md.

1. 1Check for deprecated API using references/api.md.
2. 2Check that views, modifiers, and animations have been written optimally using references/views.md.
3. 3Validate that data flow is configured correctly using references/data.md.
4. 4Ensure navigation is updated and performant using references/navigation.md.
5. 5Ensure the code uses designs that are accessible and compliant with Apple's Human Interface Guidelines using references/design.md.
6. 6Review layout behavior as windows resize, including iPad multitasking and folding iPhone Duo, using references/resizability.md.
7. 7Validate accessibility compliance including Dynamic Type, VoiceOver, and Reduce Motion using references/accessibility.md.
8. 8Check localized text, formatting, and resource handling using references/localization.md.
9. 9Ensure the code is able to run efficiently using references/performance.md.
10. 10Quick validation of Swift code using references/swift.md.
11. 11Final code hygiene check using references/hygiene.md.

What it can do on your machine

Read from SKILL.md and the folder at commit f980071. 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 (its code samples are swift).

  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

Swiftui Pro loads about 1.5k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 678 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~44

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~17k

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

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.
