fabric-variable-librarylisted

Use for Microsoft Fabric Variable Library — config-as-code for parameterizing notebooks and pipelines across environments. Covers definition parts (variables.json, settings.json, valueSets/<name>.json — no `format` field, omit it), variable types (String, Boolean, Number, Integer, DateTime, ItemReference), notebook consumption via `notebookutils.variableLibrary.getLibrary('Lib').<var>` dot notation (NOT `.get('lib','var')`) or the `get("$(/**/Lib/Var)")` reference-path form, runtime limits (same-workspace only, no SPN, active value set), the ItemReference kernel-shape trap (dict-like; `.value()` AttributeErrors), Git-sync `InvalidContent (ValueMismatch)` (stale override name or empty value), the blank-parameter + lazy-resolution pattern, the `bool('false')` → True trap, pipeline integration via the `libraryVariables` block, the type-name mapping (Boolean→Bool, Integer→Int, Number→Double, DateTime/ItemReference→String), Expression-object wrapping, `valueSetsOrder`, and the runtime-ID rule for ItemReference.

# Fabric Variable Library Config-as-code for parameterizing notebooks and pipelines per environment. Stored as a Fabric item with definition parts under source control; consumed at runtime via `notebookutils.variableLibrary` (notebooks) or the `libraryVariables` block (pipelines). ## Definition parts | Part Path | Content | Required | |---|---|---| | `variables.json` | Variable names, types, default values | Yes | | `settings.json` | `valueSetsOrder` (empty array when no Value Sets) | Yes | | `valueSets/<name>.json` | Per-environment overrides | Only when using Value Sets | | `.platform` | Item metadata JSON | No (handled by Git/REST layer) | **Critical**: VariableLibrary does **NOT** support the `format` field in definition requests. Omit it entirely — including `"format": null` may cause errors. (See fabric-rest-api skill for the definition envelope.) ## Supported variable types | Type | Description | |---|---| | `String` | Text | | `Boolean` | true / false (stored as a string!) | | `Number` | Floating-point | | `Integer` | Whole numbers | | `DateTime` | ISO 8601 | | `ItemReference` | Fabric item GUID binding (`{itemId, workspaceId}`) | ## variables.json ```json { "$schema": "https://developer.microsoft.com/json-schemas/fabric/item/variableLibrary/definition/variables/1.0.0/schema.json", "variables": [ { "name": "lakehouse_name", "type": "String", "value": "bronze_lakehouse" }, { "name": "enable_logging", "type": "Boolean", "value": "true" }, { "name
