+|--------------------------------------------------------------------------
+| Description
+|--------------------------------------------------------------------------
+|
+| Name:
+|   - Retriever
+|
+| Purpose:
+|   - Retrieve data from supported resource handlers through a unified
+|     retrieval interface.
+|
+|--------------------------------------------------------------------------
+*/
+
+/*
+|--------------------------------------------------------------------------
+| Instruction
+|--------------------------------------------------------------------------
+|
+| Guideline:
+|   - Use for retrieving data from registered JSON resource handlers.
+|   - Use type-based dispatching to route retrieval requests.
+|   - Use resource retrieval to obtain a complete JSON resource.
+|   - Use path retrieval to obtain a specific nested value.
+|   - Use fields retrieval to obtain multiple nested values.
+|   - Do not use path and fields retrieval together.
+|
+| Example:
+|   - ObrimRetriever("json", map[string]any{
+|       "resource": "metadata",
+|     })
+|
+|   - ObrimRetriever("json", map[string]any{
+|       "resource": "metadata",
+|       "path":     "app.name",
+|     })
+|
+|   - ObrimRetriever("json", map[string]any{
+|       "resource": "metadata",
+|       "fields":   []any{"app.name", "app.version"},
+|     })
