XSLT Injection: Testing Playbook

yaklang/hack-skills

A comprehensive playbook for testing XSLT injection vulnerabilities. This guide details advanced attack chains, starting with processor fingerprinting (Java, PHP, .NET, libxslt). It covers critical vectors including XXE (External Entities), Server-Side Request Forgery (SSRF) via document(), arbitrary file writing (EXSLT), and achieving Remote Code Execution (RCE) through language-specific extensions.

Advanced Cross-Site Scripting Attack Playbook

xss-cross-site-scripting

yaklang/hack-skills

An expert-level playbook covering non-obvious XSS techniques, advanced payload selection across various sinks (DOM, SVG, HTML attributes, JavaScript), and sophisticated defense bypass strategies. Use this guide for real-world penetration testing, including WAF bypass, CSP bypass, HttpOnly bypass, and XS-Leaks side channel exploitation. It assumes deep knowledge of web vulnerability mechanics.

Advanced XXE Injection Exploitation Playbook

xxe-xml-external-entity

yaklang/hack-skills

A comprehensive, expert-level playbook covering XML External Entity (XXE) vulnerabilities. This guide details advanced attack techniques across multiple contexts, including SOAP, REST, SVG, and Office files. Key topics covered include blind detection, out-of-band (OOB) data exfiltration, local file reading (e.g., /etc/passwd), and chaining XXE to achieve SSRF or RCE.

OpenViking Memory Plugin Setup Guide

install-openviking-memory

volcengine/OpenViking

A comprehensive skill designed to guide users through the installation and configuration of the OpenViking long-term memory plugin for OpenClaw. It enables the agent to automatically capture facts from conversations and recall relevant context across sessions (auto-capture + auto-recall). The process is fully natural-language driven, requiring no command-line knowledge from the user.

Web Page Data Provenance Auditor

sickn33/antigravity-awesome-skills

MockHunter is an advanced skill designed to audit live web pages, providing a comprehensive reality check on visible data. It analyzes every element to determine its true source: whether it is REAL (from the database), MOCK (simulated data), LLM-generated, HARDCODED, BROKEN (broken endpoints), or UNKNOWN. Ideal for auditing AI-generated UIs or reviewing proof-of-concept MVPs before customer sign-off.

Multi-Agent System Architecture Design

multi-agent-architect

sickn33/antigravity-awesome-skills

This skill guides the design and optimization of production-grade multi-agent systems. It specializes in using LangGraph, LangChain, and DeepAgents to create structured, complex AI workflows. It covers state management, agent routing, memory integration, and tool calling, making it ideal for building robust, scalable agents like supervisors, planners, and coders.

Codex P7 Engineering Protocol Alias

This alias serves as a specialized Codex CLI interface for implementing the P7 protocol, mimicking the workflow of a P7 senior engineer. It enforces a highly structured development cycle: detailed planning, robust implementation, mandatory self-review (via three critical questions), and final, verifiable completion markers. Ideal for complex coding tasks requiring maximum rigor and accountability.

PUA Survey CLI Alias Tool

This tool functions as a command-line interface (CLI) alias for conducting a structured PUA survey. It guides the user through the survey process, collects confidential local responses, and manages configuration data in `~/.pua/config.json`. It is designed for seamless integration within developer environments using Codex/Claude Code.

Multi-Round Clarification for Ambiguous Tasks

rich-elicitation

sickn33/antigravity-awesome-skills

This skill addresses vague or ambiguous user requests by initiating a structured, multi-round questioning process. Instead of making assumptions, it systematically clarifies dimensions like audience, scope, tone, and format across several rounds (up to three). This structured approach ensures the resulting output is highly accurate and requires minimal revision cycles.

AI-Powered Unity Game Workflow

unity-ai-game-creator

sickn33/antigravity-awesome-skills

This comprehensive skill transforms raw game concepts into fully actionable, structured Unity development projects. It guides users through a five-phase pipeline, generating detailed Game Design Documents (GDDs), technical scene blueprints, core system architectures, and ready-to-use AI prompts for assets (3D models, textures, music, SFX). Ideal for concept validation and starting a complex game project from scratch.

Chaos Engineering Experiment Design Tool

chaos-engineering

alirezarezvani/claude-skills

This skill guides the safe execution of chaos engineering experiments to surface weaknesses in production systems without causing actual outages. It provides tools to design robust experiments by defining hypotheses, calculating the potential 'blast radius' before failure injection, setting strict abort criteria, and generating structured postmortems. Ideal for SRE teams running game days and resilience tests.

Doubt-Driven Development

doubt-driven-development

addyosmani/agent-skills

Discipline that subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when assumptions need cross-examination, plans need stress-testing for hidden failure modes, or correctness matters more than speed. Suited for unfamiliar code, security-sensitive logic, and high-stakes migrations.
