# Agent surface changes

Confirmed changes to the agent surface of every tested product since its AI Agent Readiness Test. Scores stay fixed at the test date.

Monthly rechecks

Every AI Agent Readiness Score stays fixed at its test date. A recheck never changes a score.

Each month, an automated recheck repeats the five agent surface checks for every report. This page lists each confirmed change since the test.

Last recheck: 2026-09-21. It covered 69 reports.

The first recheck ran on 2026-09-21. No agent surface change is confirmed yet.

## How a change is confirmed

-   The recheck uses the same locations and methods as the test.
-   A gain needs a clean positive result, such as a valid llms.txt file or an MCP initialize result.
-   A loss needs a clean negative result, such as HTTP 404, on each of three fetches.
-   Blocked requests, rate limits, server errors, and timeouts never count as a loss.
-   A person reviews each change before it appears here. A docs AI change also needs a check in a real browser.
