I've had a lot of good luck with AI Agents also being able to read and meaningfully interprete .txt and .ansi dumps from RatatuiRuby's TestHelper module and its `assert_snapshots` [0].

For example, it was able to read the ANSI and figure out that a snapshot had changed because an upstream bug properly rendered bold and underline when it hadn't before.
