Do prompt-injection test suites predict how an agent behaves against injections written after the suite?
本文尚无中文版本；显示原文。
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.
