Skill UI

This utility ensures the prevention of silent floating-point mismatch bugs across all EVM chains. It covers runtime querying of decimals, chain-aware caching, handling precision drift in bridged tokens, and safe normalization for bots, dashboards, and DeFi tools. It is crucial for accurate cross-chain balance comparison.

This skill provides comprehensive guardrails for handling Protected Health Information (PHI) in US healthcare software. It guides development teams on data classification, security best practices, access control, and audit logging to ensure strict adherence to HIPAA regulations. Use it when dealing with patient data storage, transmission, or processing to prevent breaches and maintain compliance.

This guide addresses the critical difference between standard Node.js SHA3-256 and the Keccak-256 hash function required by Ethereum. Using the wrong hash function can silently corrupt calculated function selectors, event topics, storage slots, and derived addresses. It provides best practices and code examples for using dedicated libraries (like ethers, viem, web3.js) to ensure correct, Ethereum-compliant hashing in JavaScript and TypeScript environments.

A guide for security researchers focused on finding exploitable, remote-reachable vulnerabilities for bug bounties or responsible disclosure. It emphasizes high-signal flaws such as SSRF, RCE, and SQL injection, while guiding users through the professional triage and PoC creation process for penetration testing.

This tool enables deep inspection and validation of web applications by connecting to the browser's DevTools Protocol (MCP). It allows agents to perform tasks like DOM inspection, capturing console logs, monitoring network requests, profiling performance, and taking screenshots in a live environment. Essential for debugging UIs, validating API integrations, and performing end-to-end automated testing.

Controls BrowserWing-based browsers via HTTP endpoints to navigate pages, interact with elements (click/type/select), capture accessibility snapshots, run JavaScript, take screenshots, and execute batch sequences for data extraction workflows.

Guides AI agents through analyzing working code, spotting overly complex structures, then refactoring for clarity while preserving exact behavior and project conventions, especially after reviews or high-pressure edits.

Context Engineering Protocol optimizes agent sessions by curating persistent rules, specs, source files, and feedback so outputs stay focused, accurate, and aligned with conventions whenever you start work or the quality drops.

This guide provides a systematic, structured approach for debugging complex technical issues, such as failing tests, broken builds, or unexpected runtime errors. It teaches the 'Stop-the-Line' rule and utilizes a comprehensive triage checklist (Reproduce, Localize, Reduce, Fix, Guard, Verify) to ensure root causes are found and prevented from recurring.

Automates browser workflows with persistent page state, letting you script navigation, form filling, screenshots, scraping, or tests while keeping context across runs.

This comprehensive guide outlines idiomatic and high-quality coding standards for Dart and Flutter. It covers best practices for naming conventions, type annotations, class structure, file organization, and documentation, ensuring developers write clean, readable, and maintainable Dart codebases.

This skill provides a comprehensive guide for integrating and managing Firebase App Check in Flutter applications. It covers selecting the correct platform attestation providers (e.g., Play Integrity, DeviceCheck, reCAPTCHA), initializing the service, handling debug tokens, and executing a secure enforcement rollout. Mastering App Check is critical for protecting backend resources from unauthorized access, significantly enhancing application security.
