Browser Agent is a capability extension in Agent mode that uses a browser to complete tasks. It can open web pages, browse content, click buttons, fill out forms, scroll pages, and take screenshots to provide feedback on page status in a controlled environment, helping you complete automated tasks that “require actual web access.” Simply describe your needs in natural language during an Agent session (e.g., “check the latest prices on the official website and summarize the differences”), and the Agent will automatically dispatch the Browser Agent when needed, without requiring you to manually switch modes or write scripts.

Core Capabilities

The Browser Agent has the following main capabilities:
  • Open and Navigate Web Pages
    • Open specified web pages based on URLs you provide.
    • Jump to new pages or tabs within the same site, such as clicking navigation links or pagination links.
    • Support multi-step navigation tasks, such as “open page A -> click menu B -> enter detail page C.”
  • Read and Extract Information
    • Read visible text content on the current page, such as titles, paragraphs, lists, and tables.
    • Extract key information from pages and summarize or compare it for you in natural language.
    • “Search” for relevant information on a page based on your instructions, such as “find price-related content on this page.”
  • Interact and Operate Pages
    • Click buttons, links, switch tabs, or expand/collapse folded content.
    • Enter text in input boxes, search boxes, and other form elements, and submit forms.
    • Scroll through pages to browse more content and avoid missing key information.
  • Visual Feedback and Status Awareness
    • Take screenshots of the current page status as needed when performing complex steps, for subsequent judgment and explanation.
    • Sense whether the page has finished loading, whether a form has been successfully submitted, whether it has jumped to a new page, etc., to decide the next operation.

Usage Scenarios

You can consider using the Browser Agent in the following scenarios:
  • Information Retrieval and Comparison
    • Visit product websites, documentation sites, or blogs to extract key information and generate summaries.
    • Compare multiple pages or multiple solutions, such as price, feature, or configuration differences.
  • Online Operations and Process Walkthroughs
    • Walk through a “web-based” operation process, such as registering an account or submitting a work order (provided permissions allow and risks are controllable).
    • Help you organize typical usage steps for a web backend system and output a draft of operation instructions.
  • Assist Development and Testing
    • Open online documentation or API references to extract parts relevant to your current code.
    • Browse the interface of a web application to help you check page structure, copy, or interaction logic, and provide optimization suggestions.
It is recommended to specify goals and constraints in the task description (e.g., “read only, do not submit any forms” or “only access public documentation pages”) to help the Agent complete tasks more safely and stably.

How to Use in Agent Mode

Browser Agent is built into Agent mode and requires no separate configuration. You can invoke it in two ways:
  1. Automatic invocation: Agent mode intelligently determines when Browser Agent is needed based on your request.
  2. Explicit invocation: Use the /browser command to explicitly request Browser Agent.
Detailed usage steps:
1

Enter Agent Mode

Open Qoder’s chat panel and switch to Agent mode
2

Describe Your Task

Choose to use /browser for explicit invocation, or directly describe your needs in natural language, for example:
/browser Open https://example.com and summarize the main features
/browser Check the 2025 pricing plans and organize them into a table
/browser Analyze the theme customization options in this component library

View Results

Browser Agent will:
  • Execute necessary web interactions
  • Provide detailed explanations of actions taken
  • Share screenshots for visual verification
  • Present extracted data in structured format

Usage Suggestions and Best Practices

  • Clarify Goals and Boundaries
    • Try to explain “the result to be achieved” in one sentence, rather than just describing a single operation.
    • For security or permission-sensitive operations, clearly state “do not perform submission/payment/deletion operations.”
  • Provide Stable Entry Links
    • Prioritize providing specific page URLs rather than vague search terms, which can reduce navigation interference.
    • If you need to operate across multiple pages, you can list key pages or paths in the prompt.
  • Moderately Split Tasks
    • For very long processes (such as complex configuration wizards), you can split them into multiple small goals, execute them step by step, and confirm intermediate results.
    • After each stage ends, adjust the next instruction appropriately based on the results returned by the Browser Agent.

Safety and Limitations

When using Browser Agent, please note the following:
  • Permissions and Privacy
    • Avoid having the Browser Agent enter or expose any sensitive information (such as passwords, access tokens, personal privacy data, etc.) on web pages.
    • For operations involving account login, payment, or data writing, please prioritize manual completion, and then let the Agent perform read-only verification or explanation.
  • Page Compatibility and Stability
    • Some sites that rely heavily on front-end frameworks or complex interactions may have slow loading or difficulty identifying elements.
    • If page structure or copy changes frequently, some steps may fail to execute. In this case, you can provide a more explicit description or switch to a more stable entry page.
  • Result Reliability
    • Browser Agent’s answers are based on real-time accessed web page content, but the web page itself may not be authoritative information. It is recommended to verify yourself before making key decisions.
    • For scenarios requiring legal, compliance, or high-risk business judgment, you should not rely solely on the automated results of Browser Agent.

Through Browser Agent, you can enable Qoder to not only “understand your code” but also “understand the web pages you are visiting,” completing code editing and web page operation collaboration in the same conversation, greatly reducing the cost of switching back and forth between browsers and IDEs.
