Comprehensive design guide for web and mobile applications. Use when designing new UI components or pages, choosing color palettes and typography, or reviewing code for UX issues.
Write tests from a feature spec, treating the spec and its flow contract as the source of truth, stubbing pending tests where implementation is missing and halting when code and spec disagree. Use when the user says "write tests from this spec", "fill the coverage gaps", "prove this wizard works", or after spec-assess-coverage identifies what is untested.
Migrate ESLint and Prettier to Biome or Oxc (including Vite+), or modernize an existing config. Detects source and target configs, compares rules, flags stale nursery rules, suggests new features, and generates actionable config changes.
Audit and review application UI for IDS compliance, accessibility, usability, and cognitive load. Covers component usage validation, WCAG accessibility checks, cognitive load assessment, and UX quality evaluation. Use when asked to review UI, check accessibility, assess usability, audit IDS compliance, or when the user says "review this page", "check a11y", or "is this accessible?"
Human and accessibility skill for antislop. Contrast, keyboard, focus, and states for real people. Includes the contrast checker.
When you want to brainstorm and check available .com domains for a new project — brand naming, aftermarket pricing (HugeDomains / Afternic / Sedo / Dan), USPTO trademark screening, and social handle availability. Built on Laura Roeder's "work backwards from availability, not from a name you fell in love with" methodology. Uses Vercel CLI + whois + Domainr API + Namecheap API + agent-browser for the pieces each tool actually reliably supports (multi-tool ensemble because no single tool covers everything cleanly). 11-step workflow: budget → brainstorm → primary availability check → whois cross-check → Domainr aggregation → Namecheap price → aftermarket sweep (+ liveness probe for parked/dead domains, drop-watch for expiring ones) → bucket → negotiate → NAME research (trademark + socials) → buy. Triggers on "/domain," "find a domain," "check domain availability," "brainstorm a domain," "what .com is available for X," "domain hunt," "name my project," "is X.com available," "aftermarket price on X.com," "trademark check for X."
Implement WCAG 2.2 compliant interfaces with mobile accessibility, inclusive design patterns, and assistive technology support. Use when auditing accessibility, implementing ARIA patterns, building for screen readers, or ensuring inclusive user experiences.
286K words of color science applied to UI/UX design. Covers OKLCH/OKLAB color spaces, palette generation, accessibility contrast ratios, color naming, pigment mixing, and historical color theory. By meodai, creator of color-names.
Async message handling with Symfony Messenger; configure transports (RabbitMQ, Redis, Doctrine); implement handlers, middleware, and retry strategies
Integrate Cardcom payment processing and Israeli invoice generation into applications, covering Low Profile payments, tokenization, recurring billing, and automatic tax invoice/receipt creation per Israeli law. Use when user asks to accept payments via Cardcom, generate Israeli invoices with payments, set up "slikat ashrai" with hashbonit, handle recurring billing (hora'ot keva), or mentions "Cardcom", "CardCom API", "Low Profile", Israeli payment with invoicing, or needs combined payment plus document generation. Targets the REST API V11. Do NOT use for Tranzila integration (use tranzila-payment-gateway), general accounting, or non-payment queries.
Evaluates a flow or screen against Jakob Nielsen's 10 usability heuristics (visibility of system status, match with the real world, user control, consistency, error prevention, recognition over recall, flexibility, minimalist design, error recovery, help and documentation) and reports concrete violations. Use for a fast, structured usability pass independent of visual polish.
Use this skill to fix scroll jank, lost item state, and broken animateItem() animations in LazyColumn, LazyRow, LazyVerticalGrid, and LazyHorizontalGrid. Covers stable item keys, contentType for mixed-type feeds, Modifier.animateItem() requirements, hoisting modifier chains and painters out of the items lambda, and validating item composable stability. Use when the developer mentions LazyColumn jank, dropped frames while scrolling, items losing scroll state on insert/remove/reorder, mixed feeds of cards/headers/ads feeling sluggish, animateItem() not animating, RecyclerView view-type analog, key parameter, or contentType parameter. The prefetch-window tuning lives in a sibling skill.
