Does it capture messages sent before the skill is activated?

No, the monitor only captures connections and messages established after the instrumentation script has been successfully installed on the target page.

Does this skill support non-Chromium browsers?

No, this skill requires a Chromium-based browser as it relies specifically on Chrome DevTools Protocol (CDP) events to intercept WebSocket frames.

Can I use this for Socket.IO and engine.io applications?

Yes, it includes specific logic to detect Socket.IO and engine.io handshake patterns and automatically parses their specific packet formats.

Can I analyze binary WebSocket data with this tool?

While it primarily focuses on string and JSON payloads for readability, it tracks the size, opcode, and frequency of all frames, including binary data.

Analíticas y Monitorización

Monitors and analyzes real-time WebSocket traffic, connection lifecycles, and message payloads using Chrome DevTools Protocol.

The WebSocket Monitor skill empowers Claude to instrument web pages for deep inspection of WebSocket activity. By leveraging the Chrome DevTools Protocol (CDP), it captures connection events, tracks handshakes, and analyzes message flow with support for JSON parsing and protocol detection for Socket.IO and engine.io. This tool is essential for developers debugging connection stability, profiling bandwidth usage, or auditing real-time data exchange in modern web applications where standard network logging is insufficient.
