am-will/agent-browser

Uma CLI de automação de navegador headless rápida, baseada em Rust, com fallback em Node.js, que permite que agentes de IA naveguem, cliquem, digitem e capturem páginas usando comandos estruturados.

O que é agent-browser?

O agente-browser é uma ferramenta de automação de navegador headless de alto desempenho, implementada em Rust com fallback para Node.js. Ela permite que agentes de IA executem ações como navegação, cliques, digitação de texto e captura de snapshots (tanto de tela quanto de conteúdo HTML) de páginas web, usando comandos estruturados. A ferramenta é particularmente útil para cenários que exigem interação web dinâmica, como web scraping avançado, preenchimento de formulários e testes automatizados, tudo executado em um ambiente headless sem interface gráfica. Seu design focado em desempenho e compatibilidade com Node.js garante ampla adoção em diferentes plataformas e ferramentas de IA, como Claude Code, Cursor e Codex, fornecendo uma interface padronizada para operações de navegação. Ao utilizar Rust para a implementação principal, o agente-browser oferece velocidade e eficiência, enquanto o fallback em Node.js assegura funcionalidade em ambientes que não suportam Rust.

Documentação

O que agent-browser faz?

Uma CLI de automação de navegador headless rápida, baseada em Rust, com fallback em Node.js, que permite que agentes de IA naveguem, cliquem, digitem e capturem páginas usando comandos estruturados.

Recursos

  • Navegação headless eficiente usando Rust (com fallback Node.js)
  • Comandos estruturados: navegar, clicar, digitar, snapshot
  • Captura de snapshots de tela e HTML da página
  • Ideal para web scraping dinâmico e automação de tarefas
  • Compatível com plataformas de IA como Claude Code, Cursor e Codex

Uso

# Comando de navegação
agent-browser navegar https://exemplo.com

# Clicar em um elemento
agent-browser clicar "#botao-alvo"

# Digitar texto em um campo
agent-browser digitar "#campo-texto" "texto a ser digitado"

# Capturar snapshot
agent-browser snapshot --tipo html
agent-browser snapshot --tipo tela --caminho ./captura.png

Configuração

Defina a variável de ambiente DEFAULT_BROWSER para "rust" (padrão) ou "node" para forçar o fallback:

export DEFAULT_BROWSER=node

Requisitos

  • Rust (se usar o backend principal)
  • Node.js (para fallback)

Instalação

  1. Clone o repositório: git clone https://github.com/am-will/agent-browser.git
  2. Compile o backend Rust: cargo build --release
  3. Execute: ./target/release/agent-browser <comando>

Individual skills in this repo

This repo contains 17 individual skills — each has its own dedicated page.

am-will/context7

Fetch up-to-date library documentation via Context7 CLI. Use PROACTIVELY when: (1) Working with ANY external library (React, Next.js, Supabase, etc.) (2) User asks about library APIs, patterns, or best practices (3) Implementing features that rely on third-party packages (4) Debugging library-specific issues (5) Need current documentation beyond training data cutoff (6) AND MOST IMPORTANTLY, when you are installing dependencies, libraries, or frameworks you should ALWAYS check the docs to see what the latest versions are. Do not rely on outdated knowledge. Always prefer this over guessing library APIs or using outdated knowledge.

am-will/frontend-design

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

am-will/frontend-responsive-design-standards

Build responsive, mobile-first layouts using fluid containers, flexible units, media queries, and touch-friendly design that works across all screen sizes. Use this skill when creating or modifying UI layouts, responsive grids, breakpoint styles, mobile navigation, or any interface that needs to adapt to different screen sizes. Apply when working with responsive CSS, media queries, viewport settings, flexbox/grid layouts, mobile-first styling, breakpoint definitions (mobile, tablet, desktop), touch target sizing, relative units (rem, em, %), image optimization for different screens, or testing layouts across multiple devices. Use for any task involving multi-device support, responsive design patterns, or adaptive layouts.

am-will/gemini-computer-use

Build and run Gemini 2.5 Computer Use browser-control agents with Playwright. Use when a user wants to automate web browser tasks via the Gemini Computer Use model, needs an agent loop (screenshot → function_call → action → function_response), or asks to integrate safety confirmation for risky UI actions.

am-will/llm-council

Orchestrate a configurable, multi-member CLI planning council (Codex, Claude Code, Gemini, OpenCode, or custom) to produce independent implementation plans, anonymize and randomize them, then judge and merge into one final plan. Use when you need a robust, bias-resistant planning workflow, structured JSON outputs, retries, and failure handling across multiple CLI agents.

am-will/markdown-url

Route any website you need to visit through markdown.new by prefixing the URL. **WHEN TO USE:** - You would normally open a website link to read content (docs, blog posts, changelogs, GitHub issues, etc.) - You need a cleaner, Markdown-friendly view for copying notes or summarizing

am-will/openai-docs-skill

Query the OpenAI developer documentation via the OpenAI Docs MCP server using CLI (curl/jq). Use whenever a task involves the OpenAI API (Responses, Chat Completions, Realtime, etc.), OpenAI SDKs, ChatGPT Apps SDK, Codex, MCP integrations, endpoint schemas, parameters, limits, or migrations and you need up-to-date official guidance.

Only to be triggered by explicit /parallel-task commands.

am-will/parallel-task-spark

Only to be triggered by explicit /parallel-task-spark commands.

am-will/plan-harder

Use when user specfically says 'plan harder'.

am-will/planner

Create comprehensive, phased implementation plans with sprints and atomic tasks. Use when user says: "make a plan", "create a plan", "plan this out", "plan the implementation", "help me plan", "design a plan", "draft a plan", "write a plan", "outline the steps", "break this down into tasks", "what's the plan for", or any similar planning request.

am-will/read-github

Read and search GitHub repository documentation via gitmcp.io MCP service. **WHEN TO USE:** - User provides a GitHub URL - User mentions a specific repo in owner/repo format - User asks "what does this repo do?", "read the docs for X repo", or similar - User wants to search code or docs within a repo

am-will/role-creator
