 - **Semantic Search**: Converting a natural language query into a vector to
   perform similarity searches.
 
+## Hidden Parameter Duplication (valueFromParam)
+
+When building tools for vector ingestion, you often need the same input string
+twice:
+
+1. To store the original text in a TEXT column.
+1. To generate the vector embedding for a VECTOR column.
+
+Requesting an Agent (LLM) to output the exact same string twice is inefficient
+and error-prone. The `valueFromParam` field solves this by allowing a parameter
+to inherit its value from another parameter in the same tool.
+
+### Key Behaviors
+
+1. Hidden from Manifest: Parameters with valueFromParam set are excluded from
+   the tool definition sent to the Agent. The Agent does not know this parameter
+   exists.
+1. Auto-Filled: When the tool is executed, the Toolbox automatically copies the
+   value from the referenced parameter before processing embeddings.
+
 ## Example
 
 The following configuration defines an embedding model and applies it to
 specific tool parameters.
 
-{{< notice tip >}}
-Use environment variable replacement with the format ${ENV_NAME}
-instead of hardcoding your API keys into the configuration file.
