The first and most comprehensively benchmarked iOS skill marketplace for Claude Code, Codex, and 40+ AI coding tools.
11 enterprise-grade skills covering architecture, concurrency, testing, security, accessibility, and localization — every skill benchmarked with discriminating assertions and blind A/B quality scoring across multiple LLMs. No other iOS skill collection has this level of rigorous, reproducible evaluation — 850+ assertions across 260+ scenarios, tested on Claude Sonnet 4.6, GPT-5.4, and Gemini 3.1 Pro.
Every skill is benchmarked against multiple LLMs with discriminating assertions and blind A/B quality scoring.

- Production-first — every pattern comes from real enterprise codebases, not tutorials
- Iterative refactoring — small, reviewable PRs (≤200 lines) instead of "rewrite everything" approaches
- Anti-pattern prevention — AI tools consistently generate broken patterns (retain cycles in VIPER, outdated TCA APIs, unsafe GCD). These skills prevent that
- Architecture coverage — the only collection covering VIPER, TCA, GCD, Security Audit, Accessibility, and Localization. No other iOS skill marketplace covers these domains
- Rigorously benchmarked — the most comprehensively evaluated iOS skill collection available: 850+ discriminating assertions across 260+ scenarios, tested against 3 LLMs with blind A/B quality scoring. Every skill ships with reproducible eval data
