Skill UI

A comprehensive audit tool covering critical aspects of technical SEO, including crawlability, indexability, security headers, Core Web Vitals (LCP, INP, CLS), and robust structured data implementation. It provides expert guidance on modern challenges, such as managing AI-specific web crawlers (e.g., GPTBot, ClaudeBot) and optimizing for mobile-first indexing and JavaScript rendering best practices.

This tool provides structured guidelines and detection rules for identifying API enumeration attacks, including Broken Object Level Authorization (BOLA) and IDOR. It monitors API access logs for suspicious patterns, such as rapid sequential requests to resource identifiers, unusual status code mixes (200/403/401), and excessive attempted resource IDs, helping security teams validate API security coverage.

This skill provides comprehensive guidelines for detecting Business Email Compromise (BEC), a sophisticated fraud scheme. It covers detection techniques using email gateway rules, behavioral analytics, and robust financial process controls. Learn to identify red flags like unusual payment requests, domain mismatches, and patterns of social engineering to protect against financial loss.

This skill covers the comprehensive management of RSA key pairs, including generation, secure storage, rotation, and validation. It adheres to NIST guidelines, covering key serialization formats (PEM, DER, PKCS#8), passphrase protection, and ensuring robust key strength for digital signatures and encryption.

This tool simulates advanced security testing to identify vulnerabilities in API rate limiting. It bypasses throttling controls by manipulating request headers (like X-Forwarded-For spoofing), varying source IP addresses, and manipulating endpoint paths. Essential for assessing API resilience against brute-force attacks, credential stuffing, and resource exhaustion, aligning with OWASP API Security guidelines.

This powerful tool utilizes Playwright to record high-quality, professional web application demo videos. It simulates natural user interactions, injecting a visible cursor overlay and adhering to specific pacing guidelines. It is ideal for creating comprehensive tutorials, feature walk-throughs, or documentation for stakeholders.

Guidelines for writing clear, idiomatic Go code: line breaking, variable declarations, composite literals, control flow, and function design. Useful when reviewing Go code or setting project coding standards.

Provides comprehensive guidelines on using Go's `context.Context` for managing request lifecycles. Learn how to correctly propagate cancellation signals, enforce deadlines, handle timeouts, and safely pass request-scoped values across API boundaries (HTTP handlers, services, databases). Essential reading for writing resilient and robust concurrent Go applications.

A comprehensive guide for writing, reviewing, and structuring technical documentation for Go projects. It covers best practices for godoc comments, READMEs, contribution guidelines, and changelogs, ensuring documentation is accurate, discoverable, and tailored for both human readers and AI agents. Applicable to both libraries and CLIs.

Master the art of creating, maintaining, and running robust end-to-end (E2E) tests for Flutter applications using the Patrol framework. This skill covers validating complex user journeys, testing interactions with native system features (like permissions and deep links), capturing UI regressions, and ensuring consistent cross-platform behavior across Android, iOS, and Web. Best practice guidelines for deterministic testing are included.

Comprehensive Go testing guidance that spans table-driven subtests, testify suites, mocking, unit/integration tests, benchmarks, coverage, fuzzing, goleak leak detection, snapshot checks, and GitHub Actions CI to keep production suites reliable.

Behavioral guidelines for writing, reviewing, and refactoring code with LLMs, emphasizing minimalism, clear assumptions, surgical edits, and verifiable success criteria to avoid common machine-assisted coding mistakes.
