- screenshot-automationrshankras/claude-code-apple-skillsGenerates an automated App Store screenshot pipeline with UI tests for screenshot capture, device framing, localized caption overlays, and multi-size batch export. Use when user wants automated screenshots, App Store screenshot generation, or a fastlane snapshot replacement.TestingNo warnings★ 827↓ —
- integration-test-scaffoldrshankras/claude-code-apple-skillsGenerate cross-module test harness with mock servers, in-memory stores, and test configuration. Use when testing networking + persistence + business logic together.TestingNo warnings★ 827↓ —
- product-page-optimizationrshankras/claude-code-apple-skillsGenerates A/B test plans and optimization checklists for your App Store product page — icon, screenshots, and app previews. Use when running Product Page Optimization tests or improving conversion rates.TestingNo warnings★ 827↓ —
- characterization-test-generatorrshankras/claude-code-apple-skillsGenerates tests that capture current behavior of existing code before refactoring. Use when you need a safety net before AI-assisted refactoring or modifying legacy code.TestingNo warnings★ 827↓ —
- woo-guardamElnagdy/guard-skillsReview generated or changed WooCommerce code — extensions, payment and shipping integrations, checkout customizations, and order/product logic — before it ships. Best used reactively after an agent writes, edits, or reviews code touching WooCommerce APIs: wc_get_order, wc_get_orders, wc_get_product, WC() cart or session, woocommerce_* hooks, Store API endpoints, payment gateways, order or product meta, HPOS, subscriptions, or bookings. Use on 'review this Woo plugin', 'is this HPOS compatible', or after tasks like 'write a WooCommerce extension', 'add a checkout field', 'hook into the order flow', or 'update stock'. Enforces HPOS-safe order access, CRUD over direct meta, feature-compatibility declarations, server-side checkout validation, money-handling discipline, and hooks over template overrides. DO NOT USE for WordPress code without WooCommerce APIs (use wp-guard), generic code review (use clean-code-guard), test review (use test-guard), or store configuration and admin-screen questions.TestingNo warnings★ 1.3K↓ —
