Skill UI

A powerful command-line tool for recording the macOS screen and capturing system audio simultaneously. Unlike QuickTime or standard `screencapture`, this tool captures raw display and system audio directly via ScreenCaptureKit, eliminating the need for complex virtual audio drivers (like BlackHole) or elevated permissions. It is designed for scripted content creation, automated demos, and complex recording scenarios where system audio is required via the CLI.

A comprehensive guide and toolkit for digital forensics experts to parse and analyze raw email headers (Received, Message-ID, etc.). This method traces the true origin of suspicious emails, validates sender authenticity by analyzing SPF, DKIM, and DMARC records, and confirms or rules out email spoofing attempts. Essential for incident response and phishing investigation.

A comprehensive tool designed to discover and map adversary-controlled assets, including C2 servers, phishing domains, and exploit kits. It utilizes sophisticated pivoting techniques across passive DNS records, Certificate Transparency logs, Shodan/Censys scans, and network fingerprints (JARM/JA3S) to generate actionable threat intelligence, perfect for CTI investigations and security operations.

A comprehensive workflow and deep technical guide for analyzing malicious Linux ELF binaries. Covers static analysis (reading ELF headers, checking entropy, identifying strings), dynamic tracing (monitoring system calls and library usage with strace/ltrace), and reverse engineering (using GDB) of threats like ransomware, botnets, and rootkits targeting Linux servers and containers (x86_64, ARM).

This skill helps diagnose, repair, and prevent complex Drizzle Kit database migration conflicts. It addresses issues arising from merging branches, rebasing, or PR updates involving generated SQL, snapshots, and journals. Use it to ensure stable schema evolution in multi-developer teams and harden CI/CD workflows.

A comprehensive guide and generator for writing robust, production-grade unit and integration tests using JUnit 5 in Java. It covers advanced features like parameterized tests, Mockito mocking, lifecycle management, and nested test structures. Use this skill when you need to write clean, reliable, and highly structured Java test suites.

This skill covers the principles of building Software Development Kits (SDKs) that provide an exceptional developer experience (DX). Learn how to design intuitive APIs, utilize progressive disclosure, establish sensible defaults, and implement actionable, guiding error messages. The focus is on driving product adoption by making the developer's workflow seamless and productive. Ideal for product managers, technical leads, and API designers.

A comprehensive guide to Test-Driven Development (TDD) for Quarkus 3.x LTS, focusing on event-oriented architectures. This framework utilizes JUnit 5, Mockito, REST Assured, Apache Camel, and JaCoCo to ensure high code coverage (80%+). Use it when developing new features, fixing bugs, or refactoring event-driven services and API endpoints.

This comprehensive guide details the complete Test-Driven Development (TDD) workflow for Spring Boot applications. It covers best practices for writing unit tests (JUnit 5, Mockito), web layer tests (MockMvc), integration tests (SpringBootTest), and persistence tests (DataJpaTest). It also instructs how to use Testcontainers for realistic database simulations and achieve high code coverage with JaCoCo, ensuring robust and maintainable codebases.

The Witness toolkit provides cryptographic signing and verification for all documented code fixes. It ensures that specific fix markers remain present across all releases, and crucially, it maintains a temporal history (JSONL) allowing users to pinpoint the exact commit that introduced a regression. Ideal for robust CI/CD pipelines and release gating.

A comprehensive guide for enhancing existing agentic web applications built on the CopilotKit frontend and Microsoft Agent Framework running on Azure AI Foundry. Covers advanced topics such as adding and gating agent tools, implementing human-in-the-loop (HITL) approvals, managing shared state, debugging event streams, and safely deploying agent updates. This skill is for maintenance and extension, not for initial project scaffolding.

officecli is a robust, dependency-free CLI tool designed for working with Microsoft Office formats (.docx, .xlsx, .pptx). It allows users to programmatically create, analyze, modify, and extract structured data from complex documents, enabling advanced content manipulation, schema validation, and automated workflows entirely from the command line.
