Across 106 issues drawn from 49 repos that publish AI contribution rules, agents built on four frontier models almost never went looking for those rules on their own. Compliance happened only when someone put the rules in front of them.
Disclosure and verification are the fixable part. Reminder prompts, quoting the rule text, and feedback from a compliance checker all got agents to admit AI assistance and clear the required gates.

Why it matters
Repos are writing agent rules on the assumption agents will follow them; this checks whether they do.
Key quotes
“Our experiments on four frontier models show that today's agents almost never proactively retrieve the contribution rules.”
“Agents pick up disclosure and verification with reminder prompts, rule quotes, and verifier feedback; however, they never refuse to contribute in AI-banned repositories under any condition we tested.”
“The status reveals that verification and disclosure issues are solvable with existing mechanisms, yet enforcing bans and human escalations remains an open problem.”
“In defense, they have written contribution rules to regulate coding agents' behavior, spanning from a total ban, mandatory disclosure, to verification gates and human sign-offs.”
