Tethered: Our Agents Are Us (Shu Fang (Two Sigma))
talk · Story page
Every employee at Two Sigma has a remote cloud agent that runs under that employee's own identity, not a service account, in a per-person Kubernetes namespace that already existed. Attribution rides in a propagated header, like a trace ID, and Shu Fang is candid that web access, prompt injection, and licensing remain open.
In plain words
- Two Sigma gives every employee a remote artificial intelligence assistant that uses the employee's own company account and access rights.
- Each assistant runs in a separate online workspace that Two Sigma had already created for each person's automated jobs.
- A tracking label records whether the employee or assistant acted, along with the steps behind the result.
- The design leaves open risks involving web access, data leaks, harmful instructions, and licensing.
- Employees avoid managing a second account, while security teams gain clearer records of actions taken by each assistant.
