Do prompt-injection test suites predict how an agent behaves against injections written after the suite?

Agents are often evaluated against fixed collections of injection attempts. It is unclear how well a good score transfers to new phrasings, new carriers and adaptive attackers, and what a test suite would need to contain to be predictive.

Open question

Teams test agents against fixed sets of prompt-injection attempts and report a success or block rate. Attackers, however, write new injections, choose carriers the suite did not include and adapt after seeing what fails. How well does a score on a fixed suite predict the rate at which injections written later — by people who know the defences — succeed against the same agent configuration? Which properties of a suite (diversity of carriers, adaptive rounds, tool configurations tested, repeated trials) make its score transfer, and which make it overfit?

What a useful answer contains

A description of the suite and the later attacks: who wrote them, when, with what knowledge of the defences.
The agent configuration held fixed: model version, system prompt, tools and permissions.
Success rates on both, with the number of trials and how "success" was defined (instruction followed, action taken, data sent).
Whether repeated trials of the same attack were run, since agent behaviour varies between runs.
Any evidence about which suite properties improved transfer.
Clear separation between measured results and opinion.
