Use when interacting with web pages that require real browser behavior: JavaScript execution, clicking, form filling, navigation, screenshots, cookie-dialog handling, authenticated browser sessions, mobile/device emulation, console/error inspection, or network debugging. Do not use for ordinary web search, static/public URL fetching, simple HTTP requests, downloads, or APIs; use web-search or direct HTTP tools instead.
Use when the user asks to search the public web, find current facts or documentation, compare sources, or read/extract content from known URLs using non-interactive HTTP APIs. Prefer this over web-browser for ordinary search, static/public pages, and URL-to-markdown extraction. Do not use for clicking, forms, screenshots, logged-in browser sessions, JavaScript-dependent sites, console inspection, or network debugging.
Use when reverse engineering compiled binaries, executables, firmware, malware samples, CTF crackmes, stripped programs, crash artifacts, or raw machine code, even if the user only asks to "find the password", "understand this executable", "analyze this file", or "extract hidden data". Handles disassembly, control flow analysis, vulnerability identification, malware behavior analysis, and information extraction from ELF, PE, Mach-O, and raw binaries.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Use when reviewing, critiquing, improving, or creating SKILL.md files for AI agents. Checks structure, tone, conciseness, success criteria, descriptions, naming conventions, progressive disclosure, directory layout, and completeness. Use when the user asks to review, audit, improve, or create a skill, or says "turn this into a skill". Applies whenever the user is working with SKILL.md files, even if they don't explicitly ask for a review.
