## From README

Memory Leak Debugging This skill provides expert guidance and workflows for finding, diagnosing, and fixing memory leaks in JavaScript and Node.js applications using Chrome DevTools MCP tools. Prerequisites Advanced memory debugging tools (compareheapsnapshots, getheapsnapshotdetails, etc.) are only available when the server is started with the --memoryDebugging flag. First check if these tools are available; if not, try to read the MCP configuration file to check if --memoryDebugging is enabled. Core Principles Prefer MCP memory tools: Do NOT attempt to read raw .heapsnapshot files directly, as they are extremely large and will consume too many tokens. Use the Chrome DevTools MCP heap snapshot tools to summarize, compare, and inspect snapshots. Isolate the Leak: Determine if the leak is in the browser (client-side) or Node.js (server-side).
