Create Markdown from BrowserMCP Snapshot

This skill converts a raw accessibility tree snapshot captured by BrowserMCP (via the browser_snapshot tool) into a beautifully formatted, high-fidelity Markdown document.

Prerequisites & BrowserMCP Check

[!IMPORTANT] This skill strictly requires the BrowserMCP server to be installed and available in the environment.

Before attempting to navigate a site or capture a snapshot:

1. Verify Tool Availability: Check whether the browsermcp server and its browser_snapshot tool are present in your active MCP tools list.
2. If BrowserMCP is NOT Found:
   • Stop execution immediately and notify the user.
   • Guide the user to install BrowserMCP and configure the browsermcp server entry in their MCP configuration (e.g. in ~/.gemini/config/mcp_config.json or Antigravity MCP settings).
   • Request that the user re-run the task once BrowserMCP is enabled and available.

When to Use

Use this skill when:

• You have captured a webpage's accessibility tree YAML using the BrowserMCP browser_snapshot tool.
• You need to generate a structured, high-fidelity Markdown (.md) representation of the page content.
• You want to extract clean lists, tables, headers, blockquotes, and link destinations from the captured page layout.

Note: This skill complements browser navigation using the BrowserMCP tool. It is NOT intended to be used with other browser navigation tools, such as Playwright or the Antigravity built-in browser agent. Be sure to be explicit about what tools to use and what to avoid.

How it Works

The skill runs a Python parser that reads the captured accessibility tree YAML snapshot, builds a parent-child node hierarchy, and recursively converts the tags and properties into Markdown text.

Execution Procedure

1. Verify BrowserMCP: Confirm browsermcp is installed as detailed in Prerequisites & BrowserMCP Check. If absent, guide the user to install it.
2. Capture Snapshot: Navigate to the target URL using browser_navigate and run browser_snapshot to output the accessibility tree YAML.
3. Execute Parser: Run the Python script parse_snapshot.py passing the absolute path of the captured snapshot text file as an argument and specifying the output Markdown path:
