 - **Error Message**: A clear, human-readable message describing the error. This should provide enough detail to inform users or developers of the root cause or required action.
 
-- **Target Prompt**: The specific prompt or operation where the error occurred. Understanding where the error happened helps with debugging and pinpointing the source of the problem.
-
 - **Parameter-Specific Errors**: Errors that arise due to invalid or missing parameters when invoking a function. These errors are critical for ensuring the correctness of inputs.

 Prompting LLMs
 --------------
-Arch is a single piece of software that is designed to manage both ingress and egress prompt traffic, drawing its
-distributed proxy nature from the robust `Envoy <https://envoyproxy.io>`_. This makes it extremely efficient and capable
-of handling upstream connections to LLMs. If your application is originating code to an API-based LLM, simply use
-the OpenAI client and configure it with Arch. By sending traffic through Arch, you can propagate traces, manage and monitor
-traffic, apply rate limits, and utilize a large set of traffic management capabilities in a centralized way.
