airbnb-swift-style

If you've reviewed my iOS code, you know I love the Airbnb Swift Style Guide. So I published my first agent skill to enforce it for AI coding agents.

It works with Claude Code, Cursor, and any tool that supports the Agent Skills open format, automatically reviewing Swift code for naming, formatting, and pattern violations based on Airbnb's style guide.

What it does

• Reviews and lints. Scans any Swift file or snippet, groups findings by category (Naming, Formatting, Style, Patterns), quotes the offending line, and gives back a corrected version.
• Enforces naming. Casing, boolean prefixes (is, has, does), acronym capitalization, and past-tense event handlers (didTapSave, not handleSave).
• Enforces formatting. The 100-character line limit, 2-space indentation, and trailing whitespace.
• Applies style patterns. Redundant self, type inference, force-unwrapping, guard early exits, and most-restrictive access control.
• Rewrites code. Returns a clean version of any snippet with a summary of every change it made.

Why I built it this way

• Grounded in the actual guide. Every rule maps back to a section of Airbnb's guide. If there's ever a discrepancy, the upstream guide wins.
• It works alongside your linters. SwiftFormat and SwiftLint already handle mechanical formatting. This handles the judgment calls: naming intent, pattern choice, and access control.
