Ideal for cron jobs, CI/CD pipelines, and agent turn notifications.

A comprehensive guide for building or reviewing SwiftUI User Interfaces that utilize the modern Liquid Glass aesthetic. This skill focuses on correctly implementing native Apple APIs (like `glassEffect` and `GlassEffectContainer`) while ensuring proper fallback mechanisms, modifier ordering, and performance for iOS 26+ devices. Ideal for adopting cutting-edge iOS design patterns.

An advanced reliability wrapper for AI agents that monitors, manages, and recovers from tool call failures. It automatically handles common issues such as truncated JSON responses, API timeouts, rate limits, and mid-chain process breakdowns. By implementing sophisticated failure classification, checkpointing, and learning mechanisms, Guardian ensures complex, multi-step agent workflows remain stable and resilient.

Build communication features using Twilio APIs for SMS, voice calls, WhatsApp Business, and 2FA verification. Supports IVR systems and multi-channel authentication. Essential for integrating programmable messaging and phone verification into applications.

This skill humanizes natural-language memory files like CLAUDE.md, AGENTS.md, and docs by removing AI-isms and adding burstiness. It offers deterministic and LLM modes, preserves code blocks, URLs, paths, and headings, and creates backups. Ideal for cleaning up AI-generated content in configuration files and documentation.

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.

A comprehensive skill for conducting client-side injection vulnerability assessments on web applications. It identifies XSS and HTML injection flaws, demonstrates exploitation techniques for session hijacking and credential theft, and validates input sanitization and output encoding mechanisms. Includes practical examples and strict safety guardrails.

Generate or modify Nightingale (n9e) alert notification message templates using Go text/template syntax, including variables, helper functions, and channel-specific escaping for DingTalk, Feishu, email, SMS, and voice.
