Anti-slop check

Gesso

Deterministic design critique for HTML/CSS screens. Runs 73 slop guards extracted from the set of rules professional designers use in production-grade designs to catch the tells that make UI read as AI-generated (gradient-clipped headlines, the default indigo accent, puffy shadows, emoji icons, fake dot charts and decorated gauges, badges floated over the hero, eyebrow kickers above the H1, fake magazine mastheads, colored edge-stripe rails, two-tone headlines, over-designed list rows, layout-collapse bugs, em-dash copy, placeholder imagery), auto-fixes what can be safely rewritten, and reports the rest with concrete edits. Use whenever generated or hand-written HTML/CSS is about to be shown, exported, shipped, or committed, or when asked to critique a design, check it for slop, or give a second opinion on a generated screen.

SVG Diagramming Conventions

Bybit

SVG diagramming conventions blending a technical look with CJK-friendly typography. Use when creating flowcharts, architecture diagrams, and similar SVG figures. For one-shot generation, prefer invoking it from a subagent so the main context does not have to carry this skill plus the SVG XML; for multi-round tweaking, use it directly in the main context.

AntV

Use this skill whenever the user wants to create, customize, or troubleshoot G2 v5 chart visualizations. Triggers include: any mention of 'G2', 'antv g2', '@antv/g2', 'G2 chart', 'G2 可视化', or requests to produce charts like bar charts (柱状图), line charts (折线图), pie charts (饼图), scatter plots (散点图), area charts (面积图), heatmap (热力图), radar charts (雷达图), treemap (矩形树图), funnel charts (漏斗图), sankey diagrams (桑基图), gauge (仪表盘), wordcloud (词云), boxplot (箱线图), as well as G2-specific topics like encode channels, scale config, coordinate systems, transforms, interactions, themes, labels, and animations. Also use when debugging G2 rendering errors, V4→V5 migration issues, or chart type selection. Do NOT use for G6 graph/network visualization, X6 editor diagrams, or S2 pivot tables.
