Inside Interception Servers for Agent Evals

xeophon · x · 2026-07-13

This post details a key implementation aspect for agent evaluation/execution: the interception server is the layer that actually sends requests, rather than the harness itself, granting users far greater control.

The author points out a detail missing from Codex screenshots: the temperature parameter, which is configurable in their verifiers v1. Replies emphasize that this interception design offers more than just "elegant implementation details"—it provides real-time generation traces, preventing post-processing tampering with the transcript.
