+### quantify
+
+Run quantity take-off (QTO) on an IFC file, computing physical measurements
+(volume, area, length, count, weight) and writing them back as
+`IfcElementQuantity` property sets. Uses `ifc5d` rules.
+
+**List available rules:**
+
+```bash
+ifcedit quantify list
+```
+
+```json
+[
+  {"name": "IFC4QtoBaseQuantities"},
+  {"name": "IFC4X3QtoBaseQuantities"}
+]
+```
+
+**Run QTO on a file:**
+
+```bash
+ifcedit quantify run model.ifc IFC4QtoBaseQuantities
+ifcedit quantify run model.ifc IFC4QtoBaseQuantities --selector IfcWall
+ifcedit quantify run model.ifc IFC4QtoBaseQuantities -o model_qto.ifc
+```
+
+```json
+{"ok": true, "rule": "IFC4QtoBaseQuantities", "elements_quantified": 42}
+```
+
+Options:
+
+- `--selector <query>` -- ifcopenshell selector to restrict elements (default: all `IfcElement`)
+- `-o, --output <path>` -- write to a different file instead of overwriting the input
+
+Note: `quantify run` writes geometry-based measurements and requires the
+IfcOpenShell C++ geometry bindings for elements with computed quantities.

 `ifcedit` and `ifcquery` are complementary tools:

+- **ifcedit** modifies IFC models by wrapping `ifcopenshell.api` functions, and runs QTO via `quantify`
 
 A typical workflow: inspect with `ifcquery`, look up the right API function
 with `ifcedit docs`, then apply changes with `ifcedit run`.

+#### ifc_validate
+
+Check the model for schema and constraint violations.
+
+```
+ifc_validate()
+ifc_validate(express_rules=True)
+```
+
+Returns `{"valid": true, "issues": []}` or `{"valid": false, "issues": [{"level": "ERROR", "message": "..."}]}`.
+
+#### ifc_schedule
+
+List all work schedules and their nested task trees.
+
+```
+ifc_schedule()
+ifc_schedule(max_depth=1)   # top-level phases only
+```
+
+`max_depth` limits subtask expansion. At the cutoff, `subtasks` is replaced
+with `{"truncated": true, "count": N}` so you know children exist without
+fetching them all. Omit for unlimited depth.
+
+#### ifc_cost
+
+List all cost schedules and their nested cost item trees.
+
+```
+ifc_cost()
+ifc_cost(max_depth=2)   # top two levels of the BoQ
+```
+
+`max_depth` limits cost item expansion, same truncation convention as
+`ifc_schedule`.
+
+#### ifc_schema
+
+Return IFC class documentation for any entity type, using the loaded model's
+schema version.
+
+```
+ifc_schema(entity_type="IfcWall")
+ifc_schema(entity_type="IfcBuildingStorey")
+```
+
+Returns description, predefined types, spec URL, and attribute descriptions.
+Returns `{"error": "Unknown entity: Foo"}` for unrecognised types.
+
+#### ifc_quantify
+
+Run quantity take-off (QTO) on the loaded model using an `ifc5d` rule.
+Computes physical measurements (volume, area, length, count, weight) and
+writes them back as `IfcElementQuantity` property sets. Modifies the model
+in-place -- call `ifc_save()` when done.
+
+```
+ifc_quantify(rule="IFC4QtoBaseQuantities")
+ifc_quantify(rule="IFC4QtoBaseQuantities", selector="IfcWall")
+```
+
+Available rules: `IFC4QtoBaseQuantities`, `IFC4X3QtoBaseQuantities`.
+
+`selector` is an optional ifcopenshell selector to restrict which elements
+are quantified (default: all `IfcElement`).
+
+Returns `{"ok": true, "rule": "...", "elements_quantified": 42}`.
