This wrapper provides a mechanism to integrate x402 payment walls into Node.js/Express APIs. It enforces micropayments (USDC on Base L2) for API access, enabling robust machine-to-machine (M2M) monetization. By acting as middleware, it requires valid payment signatures, ensuring that every API call is monetized and payments are liquidated atomically.

This skill generates a comprehensive, professional, and print-ready invoice document. It structures the output with sender and recipient blocks, detailed line items, tax breakdowns, subtotals, and full payment instructions. Use this when documenting bills, invoices, or billing statements for any business transaction.

This router guides the testing of systemic flaws in business processes and state machines. It is essential when vulnerabilities stem from workflow abuse, race conditions, pricing flaws, or multi-step state attacks, rather than simple input sanitation issues. Use it to test complex business flows like payments, inventory management, and approval sequences.

A powerful PreToolUse hook designed to act as a safety net during code writing sessions. It automatically scans both file paths and content for 12 common security anti-patterns, including SQL injection, XSS, command injection (Node.js/Python), and unsafe deserialization. It blocks the writing operation and provides immediate warnings, ensuring adherence to secure coding practices when handling sensitive code like authentication or payment logic.

This skill helps structure the foundational commercial policies governing discounting off list price. It builds three deterministic tools: a 4D discount matrix builder (considering ARR, term length, payment terms), an exception flow router with compensating commitments, and a policy linter to detect governance gaps. It is designed for Heads of Commercial and RevOps to establish defensible rules of engagement, ensuring margin adherence and preventing discount drift, rather than for approving individual deals.

This meta-skill is designed for complex decision analysis when a user provides or references structured documents such as contracts, quotes, spreadsheets, or notices. Instead of simple summarization, it extracts key evidence, identifies risks (e.g., renewal risk, payment terms), and structures the output into decision-ready formats, such as 'sign/reject/negotiate' recommendations, evidence tables, or required next actions. It supports input from PDF, DOCX, and XLSX formats.

This skill guides users through expert offer construction, focusing on improving the foundational value proposition rather than just optimizing copy. Learn to master the Value Equation (Dream Outcome, Likelihood, Time Delay, Effort/Sacrifice) and structure a complete offer using key components like bonus stacking, robust guarantees, urgency creation, and ideal payment models. Ideal for services, coaching, courses, and high-ticket B2B direct response sales.

This guide details the process of deploying and configuring Proofpoint Email Protection, a cloud-native Secure Email Gateway (SEG). It establishes a critical security checkpoint for all mail traffic, protecting users from advanced threats including phishing, malware, Business Email Compromise (BEC), and spam. The implementation covers architectural planning, advanced threat defense (sandboxing, ML classifiers), and compliance with protocols like DMARC, SPF, and DKIM.

Business Email Compromise (BEC) is a sophisticated fraud scheme relying on social engineering. This skill provides comprehensive guidance on detecting and mitigating BEC attacks. It covers using email gateway rules, behavioral analytics, and implementing financial controls to identify impersonation attempts, altered payment details, and urgent fraudulent requests.

This skill analyzes ransomware cryptocurrency payment flows by utilizing major blockchain intelligence APIs (like Chainalysis and WalletExplorer). It identifies wallet clusters, tracks movements through obfuscation services (mixers, tumblers), and determines fund flows to exchanges, supporting forensic investigations and law enforcement attribution efforts.

This skill provides a comprehensive defense-in-depth framework for securing autonomous AI agents. It implements least-privilege tool allowlisting, identity binding, and human-in-the-loop controls to mitigate risks like prompt injection and tool poisoning. Use this when building agents that interact with sensitive systems (e.g., payments, file writes) to ensure governance, auditability, and compliance.

This skill mints tamper-evident, post-quantum-signed receipts for consequential agent actions (e.g., deployment, payment, access grant). It records who, what, and under which policy the action occurred, ensuring the evidence cannot be altered later. By providing verifiable proof from the certificate alone, it is crucial for meeting regulatory compliance requirements, such as the EU AI Act, and building auditable, trustworthy systems.
