Use this skill when the user needs to test features before deployment, create test scenarios, find edge cases, or verify bug fixes. Covers manual testing workflows, cross-browser testing, edge case identification, and testing checklists for non-technical founders.
Production-ready microscopy image analysis and quantitative imaging data skill for colony morphometry, cell counting, fluorescence quantification, and statistical analysis of imaging-derived measurements. Processes ImageJ/CellProfiler output (area, circularity, intensity, cell counts), performs Dunnett's test, Cohen's d effect size, power analysis, Shapiro-Wilk normality tests, two-way ANOVA, polynomial regression, natural spline regression with confidence intervals, and comparative morphometry. Supports CSV/TSV measurement tables, multi-channel fluorescence data, colony swarming assays, and neuron counting datasets. Use when analyzing microscopy measurement data, colony area/circularity, cell count statistics, swarming assays, co-culture ratio optimization, or answering questions about imaging-derived quantitative data.
Apple Human Interface Guidelines for layout and navigation components. Use this skill when the user asks about "sidebar", "split view", "tab bar", "tab view", "scroll view", "window design", "panel", "list view", "table view", "column view", "outline view", "navigation structure", "app layout", "boxes", "ornaments", or organizing content hierarchically in Apple apps. Also use when the user says "how should I organize my app", "what navigation pattern should I use", "my layout breaks on iPad", "how do I build a sidebar", "should I use tabs or a sidebar", or "my app doesn't adapt to different screen sizes". Cross-references: hig-foundations for layout/spacing principles, hig-platforms for platform-specific navigation, hig-patterns for multitasking and full-screen, hig-components-content for content display.

Apply principles of good design taste when creating, reviewing, or critiquing any creative or technical work. Use this skill whenever the user asks you to design something, review a design, create UI/UX, architect a system, write something with aesthetic intent, evaluate the quality of code or creative work, or asks for feedback on whether something is "good." Also trigger when users mention taste, aesthetics, beauty in design, elegance, simplicity, or when they want help making something not just functional but genuinely well-crafted. This skill applies across domains: software, writing, visual design, architecture, presentations, APIs, data models, and more. Even if the user doesn't explicitly mention "design," use this skill when the underlying task is about making something better, more elegant, or more refined.
