Forces you to investigate root causes before attempting any fixes through a rigid four-phase process: evidence gathering with diagnostic logging at component boundaries, pattern analysis against working examples, hypothesis testing with minimal changes, and proper test-driven implementation. Specifically prevents the "quick fix" trap by requiring you to trace data flow, add instrumentation to multi-layer systems, and stop after three failed attempts to question the underlying architecture. Most useful when you're under pressure and tempted to guess, or when dealing with complex systems where symptoms appear far from causes.

The skill audits and fixes HTML metadata across a website, including page titles, meta descriptions, canonical URLs, Open Graph tags, Twitter cards, favicons, and structured data. It serves developers and SEO practitioners shipping new pages or improving social share previews and search engine visibility. It solves the problem of incomplete or inconsistent metadata by providing a prioritized workflow that ensures metadata correctness, prevents duplicates, and aligns social card rendering with canonical URLs.

swiftui-performance-audit

dimillian/skills

2.3k

The swiftui-performance-audit skill diagnoses and resolves SwiftUI runtime performance issues through a structured code-first review followed by runtime profiling when needed. It serves SwiftUI developers experiencing symptoms like slow rendering, janky scrolling, high CPU/memory usage, or excessive view updates, helping them identify root causes such as invalidation storms, unstable list identity, heavy work in view bodies, layout thrash, or main-thread image processing. The skill guides users through code analysis using a smell catalog, and when code review is inconclusive, provides a systematic profiling intake process to gather runtime evidence and validate remediation steps.
