Axiom Swift Performance

Summary

You're writing Swift code and Claude keeps suggesting Date() instead of Date.now, or hallucinating APIs that don't exist. This skill fixes that with modern idiom patterns, ownership conventions for noncopyable types, and complete Transferable reference for drag and drop. The tvOS section alone is worth it if you've ever wondered why your app compiles fine but the focus system breaks at runtime. The deep link debugging workflow cuts iteration time from minutes to seconds when testing navigation flows. Honestly, the anti-rationalization table at the end calling out CGFloat and Info.plist gotchas is the kind of thing you bookmark after getting burned once.

bug-review

pproenca/dot-skills

Use this skill when a user asks to review a pull request for bugs, wants AI code review focused on correctness issues, or runs /bug-review. Trigger on PR review, bug finding, code review, "review this PR", "check for bugs", "find issues in this PR". This is a multi-pass review workflow with 5 parallel passes, majority voting, independent Opus validation, and resolution rate tracking. Also trigger on /bug-review:resolve to classify whether findings were fixed at merge time, and /bug-review:report for resolution rate stats. Even if the user just says "review this" while on a PR branch, trigger this skill.
