    "incantation": "When inspecting a node’s outgoing heap snapshot edges, call `get_heapsnapshot_edges` with the snapshot path and node ID. Set `excludePrimitives: false` to include primitive targets; optionally filter by minimum retained bytes or choose an edge sort order.",
    "examples": [
      "get_heapsnapshot_edges({\"filePath\":\"<path-to-heapsnapshot>\",\"nodeId\":<node-id>,\"excludePrimitives\":false,\"minRetainedSize\":<bytes>,\"sortBy\":\"name\"})"
    ],
    "gotchas": [
      "Version: 1.8.0",
      "filePath (required): Path to the .heapsnapshot file to read.",
      "nodeId (required): Node ID whose outgoing edges to return.",
      "excludePrimitives: Whether to exclude primitive target nodes; defaults to true. Set false to include them.",
      "minRetainedSize: Minimum retained size in bytes for target nodes.",
      "sortBy: Sort edges by retainedSize, selfSize, or name; defaults to retainedSize. Values are alternatives.",
      "Prerequisite: Enable memory debugging with `--memoryDebugging=true`.",
      "`minRetainedSize` is measured in bytes.",
      "`sortBy` accepts `retainedSize`, `selfSize`, or `name`.",
      "Docs conflict: The newer v1.8.0 tag documentation lists `retainedSize` instead of `minRetainedSize` and omits `minRetainedSize`; this conflicts with the release note. Use the release-note parameter only as documented at the feature commit."
