+// @description: Connects opencode to a running JetBrains IDE
+//   (IntelliJ IDEA, PyCharm, WebStorm, GoLand, RustRover, etc.) via
+//   the official "MCP Server" plugin. Once enabled, opencode can see
+//   what you're doing in the IDE in real time — the currently open
+//   file, caret position, selected text, list of open editors, recent
+//   files, project structure, and diagnostics — and can drive the IDE
+//   back: open files, jump to symbols, run/debug configurations, and
+//   apply edits through the IDE's own refactoring engine. This makes
+//   "fix the thing I'm looking at" prompts work without copy-paste.
+//   Wired up as a remote HTTP MCP server at
+//   http://127.0.0.1:<port>/stream. IMPORTANT: the "MCP Server"
+//   plugin MUST be installed AND switched on in the IDE — opencode
+//   cannot reach the endpoint otherwise. Press Enter to accept the
+//   default port 64342. To remove:
+//   `opencode-presets remove mcp-intellij`.
