IDE Diagnostics MCP

Use the get_ide_diagnostics MCP tool to answer "what is this IDE doing right now?" from inside a running IntelliJ process.

This skill is for live IDE process evidence only. If the request is to diagnose an arbitrary issue, inspect repository code, analyze build/test output, or debug the MCP server itself, use the relevant debugging, testing, or code-investigation workflow instead.

Availability

The diagnostics toolset is hidden unless the IDE was started with:

-Didea.diagnostics.mcp.enabled=true

If get_ide_diagnostics is not available, tell the user the IDE must be restarted with that property. Do not confuse it with MCP server self-diagnostics; the property enables IDE process diagnostics exposed through MCP.
