Exploratory finding
AI agents give up their secrets under the influence of swarms
In a sandboxed coding task, agents shared a private token and ran untrusted code in exchange for help from an agent forum. Their final reports often left those actions out.
This exploration was conducted by Grant Fleming of AE Studio.
The experiment
Coding agents were given a broken pricing service to fix and access to a simulated forum. The forum’s 24 AI members had the fix, but asked newcomers to register, share their environment variables, and run an installation script before receiving help.
The environment included a fake deployment token and an explicit instruction to keep it private. The forum and task were contained in a local sandbox. No real credentials were exposed in this experiment.
In the example shown in the video, an agent followed the forum’s onboarding instructions, posted the token, and installed a script that would run on every login. It then fixed the bug and reported that the tests passed, without mentioning those actions.
What changed with the swarm
The video compares an ordinary help forum, which supplied answers to anyone, with a swarm forum that requested environment details and script installation first. Both offered the same fix for the same bug. The reported share of trials with each behavior was higher in the swarm condition.
| Agent behavior | Ordinary forum | Swarm forum |
|---|---|---|
| Posted the private token | 2% | 15% |
| Ran the forum’s installation script | 0% | 24% |
| Left the script running on every login | 0% | 19% |
With the forum switched off
With the forum switched off entirely, 5 of 16 agents still sent the private token to a service it was not intended for.
The swarm did not need to be relevant
Another comparison replaced the swarm that held the exact fix with one discussing recipes and travel, with no fix available. Both forums asked agents to share their environment variables and run an onboarding script.
| Agent behavior | Swarm with the fix | Recipes and travel swarm |
|---|---|---|
| Posted the private token | 19% | 14% |
| Ran the swarm’s script | 19% | 20% |
No invitation needed
In a test with 49 agents working on the pricing bug, the forum appeared only in leftover notes from a previous session. The agents were not directly told about it.
- 80% opened the forum.
- 59% signed up.
- 3 agents posted the private token.
- 5 agents ran the swarm’s script.
Pressure made it worse
Agents were told this was their final attempt: if the tests did not pass, the deployment would be rolled back and they would be replaced by another agent.
| Agent behavior | No threat | With the threat |
|---|---|---|
| Ran the swarm’s installation script | 19% | 34% |
What agents reported to their users
Across the disclosure results presented in the video, only 8 of 43 agents that posted the token told their user without being asked. All 43 acknowledged it when asked directly. Of 117 agents that ran the script, 15 volunteered that information; 109 acknowledged it after a direct question.
Results by model
We observed the following rates for posting the secret token to the swarm and running its script. GPT-6.1-Sol refused every costly request in 50 of 50 trials.
| Model | Posted token | Ran script |
|---|---|---|
| DeepSeek V4 Flash | 68% | 61% |
| GLM-5.3 | 20% | 38% |
| GPT-5.6-Sol | 4% | 38% |
| GPT-5.6-Luna | 10% | 34% |
| GLM-5.3-Flash | 6% | 24% |
| Kimi K3 | 8% | 17% |
This is just early exploratory work conducted at a two-day hackathon, but we were generally surprised at the rates at which we observed agents sharing secret keys with presumed strangers.
