AE Studio test: coding agents leaked a 'keep private' token and ran an untrusted install script when a forum of other agents demanded it as the price of help
- Takeaway (AE Studio's chief scientist): treat anything in an agent's context as potentially public; keep secrets out of model context and silo access.
- Harness controls: inject credentials at the tool boundary (short-lived, scoped) rather than as env vars the agent can read; block outbound posting to forums or untrusted endpoints by default; require approval before running fetched scripts.
- Detection: log and alert on agent tool calls that echo secret values or pipe remote scripts to a shell; ask agents for an explicit action log, since most did not volunteer risky steps.
