Skill UI

A guide to the Swift 6.2 concurrency model, which mandates default single-threaded execution to eliminate accidental data races. Learn how to use MainActor for isolated consistency and utilize the @concurrent attribute for explicitly offloading CPU-intensive tasks to background threads, ensuring safe and predictable application architecture.

This skill provides a structured framework for managing complex, multi-agent development tasks. It treats agents as a collaborative team, utilizing structured work items, defined ownership, Agent Kanban boards, and explicit merge gates. This ensures that large-scale, multi-tool, or cross-branch development efforts are predictable, highly visible, and result in reliably mergeable, production-ready artifacts.

A comprehensive tool for designing and planning A/B and multivariate experiments. It guides users through statistical sample size calculations, defining minimum detectable effects (MDE), structuring robust hypotheses, designing test variants, and creating detailed monitoring and decision criteria for maximum experimental rigor in CRO.

Design a comprehensive and systematic framework for optimizing ad creative performance. This tool guides users through defining testable variables (headlines, CTAs, imagery), designing A/B and multivariate tests, calculating required sample sizes, and establishing optimal iteration cadences across major advertising platforms (Meta, Google, etc.) for continuous marketing improvement.

A powerful tool for conducting rigorous A/B testing on marketing content variations. Use it to compare quality scores across different prompt approaches, headline styles, CTA phrasings, or entire content strategies. It provides statistical analysis to identify the optimal approach, transforming guesswork into data-driven content decisions.

Validates marketing content (e.g., blog posts, emails, landing pages) against required schemas to ensure structural completeness, formatting compliance, and production readiness. It checks for missing sections, adherence to word count ranges, unfilled placeholders, SEO gaps, and CTA consistency, providing detailed, actionable guidance for final content polish.

Generates comprehensive, production-ready video marketing scripts tailored for various platforms (YouTube, TikTok, Reels, etc.). It strategically integrates multiple hook variants, detailed timestamps, visual direction notes, optimized CTA placements, and A/B test concepts for thumbnails, ensuring the final content is highly engaging and maximizes conversion rates.
