+# crossplane_function_kcl_utils
+
+A KCL package that provides schemas and utility functions for writing safer and more productive Crossplane Functions in KCL. This module enhances type safety and IDE support when working with function-kcl.
+
+## Installation
+
+To install this package, run the following command:
+
+```bash
+kcl mod add oci://ghcr.io/appthrust/kcl/crossplane_function_kcl_utils
+```
+
+## Usage
+
+### get_params()
+
+The `get_params()` function provides type-safe access to the function pipeline's parameters. While `option("params")` returns `any` type, this function returns a strongly-typed `Params` schema.
+
+```python kcl
+import crossplane_function_kcl_utils as utils
+
+# Get type-safe params
+params = utils.get_params()
+
+# Access params with IDE support
+print(params.oxr)        # Observed composite resource
+print(params.ocds)       # Observed composed resources
+print(params.dxr)        # Desired composite resource
+print(params.dcds)       # Desired composed resources
+print(params.ctx)        # Pipeline context
+print(params.extraResources)  # Extra resources
+```
+
+### Params Schema
+
+The `Params` schema provides a type-safe structure for function pipeline parameters:
+
+```python kcl
+schema Params:
+    """
+    Params are the input parameters for the function pipeline.
+    """
+    oxr: Resource           # Observed composite resource (XR)
+    ocds: {str:Composite}   # Observed composed resources
+    dxr: Resource          # Desired composite resource (XR)
+    dcds: {str:Composite}   # Desired composed resources
+    ctx: any               # Function pipeline's context
+    extraResources: {str:[Composite]}  # Extra resources
+```
+
+Note: A composed resource can be a managed resource, ProviderConfig, composite resource, or any other Crossplane resource.

+    ocds : {str:Composite}, default is None
+        Key-value of the observed state of a composed resource. The key is the name of the composed resource.
