pixel-pusher
by slamb2k
Comprehensive UI/UX design system for creating professional web interfaces through structured multi-stage process. Use when users request website designs, landing pages, web apps, UI mockups, design systems, or interface prototypes. Guides through requirements gathering, design system creation from references/screenshots, HTML mockup generation, iterative refinement, and final design delivery. Ideal for "design me a website", "create a landing page", "build a UI for X", or providing design inspiration screenshots/URLs.
play-tight
by slamb2k
Context-efficient browser automation using Playwright scripts and subagent isolation. Use when you need to interact with web pages, extract data from websites, verify page elements, or automate browser tasks while avoiding context window pollution from verbose HTML/accessibility trees. Provides both direct script execution and a specialized subagent pattern for complex investigations that generate large intermediate responses.
bio-atac-seq-differential-accessibility
by GPTomics
Find differentially accessible chromatin regions between conditions using DiffBind or DESeq2. Use when comparing chromatin accessibility between treatment groups, cell types, or developmental stages in ATAC-seq experiments.
bio-atac-seq-motif-deviation
by GPTomics
Analyze transcription factor motif accessibility variability using chromVAR. Use when identifying which TF motifs show variable accessibility across samples or conditions in ATAC-seq data.
qa-find-bugs-dashboard
by bex-co
Exercise the running Beancount.io dashboard with headless Playwright, use QA_EMAIL and QA_PASSWORD for login, reproduce bugs, trace fixes to source, and deduplicate findings. Use for dashboard QA or a browser bug hunt. Skip ordinary code review, bug implementation, and native-mobile QA (use qa-find-bugs-mobile).
e2e-testing
by oakoss
'E2E test architecture and patterns with Playwright. Use when designing test suites, structuring Page Object Models, planning CI sharding strategies, setting up authentication flows, or organizing tests with tags and annotations. Use for test architecture, accessibility auditing with axe-core, network mocking strategies, visual regression workflows, HAR replay, and storageState authentication patterns. For Playwright API details, browser automation, or web scraping, use the playwright skill instead.'
design-system
by oakoss
'Builds scalable design systems with tokens, theming, and component architecture. Use when creating design token hierarchies, theming systems, component variant patterns, or accessibility foundations.
