KEEP CRE=
DENTIALS OUT OF YOUR AGENT'S CONTEXT (SPONSOR) [4]=20
An agent that rea=
ds a web page, a Jira comment, or an inbox can pick
up instructions an at=
tacker wrote. If a Slack or Salesforce token is
sitting in that same proc=
ess, it's exposed too.
Here's how you can keep credentials away from a=
gents with WorkOS [5]:
PIPES handles OAuth, token refresh, and encr=
ypted credential
storage behind a drop-in widget.
RELAY, now in e=
arly access, routes your agent's API calls through
WorkOS, which attaches=
the credential server-side [6] and restricts
requests to allowed provide=
r hosts. Permissions and other outbound
paths still need their own contro=
ls.

Physicists at Northwestern University have coaxed a single positron=

resulting in a sta=

artificial atom with quantum e=

Anthropic's Claude Duet joins a fast-gr= owing field of AI assistants that take actions and perform tasks on their o= wn. Unlike OpenAI's dots and Meta's Muse, Anthropic's agent was built for w= ork and is less capable at personal errands. It can connect to more than 6,= 000 outside apps and make purchases through Link, Stripe's digital wallet, = and Shopify's Shop Pay. The agent shows users exactly what it plans to do b= efore performing actions, and some actions, like trading stocks or moving m= oney between accounts, are blocked even with user approval. The wait list t=

Tesla has started production of its Opt= imus humanoid robot at its factory in Fremont, California. While the compan=
y admits there is still more work to be done before the robot is fully safe=
and reliable, it says it has proven that the current manufacturing process=
for Optimus is suitable for a commercial product. Elon Musk says Tesla wil=

ts cooled the fast-moving particle to nearly absolute zero after capturing =
it from radioactive decay, and then suspended it in a near-perfect vacuum, = resulting in a state where the positron behaved much like an artificial ato=

<strong>The Topology of an LLM Agen=

</span>
<span style=3D"font-family: "Helvetica Neue", Helvetica, Arial, V= erdana, sans-serif;">
An agent is three things: a model, an a= gentic loop, and a set of tools. Where these run has implications for cost,=
capability, effectiveness, and security. If you focus on topology, you can=
break down any agentic product and reason about what a product can and can= not do. There isn't one perfect loop - good UX for a general-purpose chatbo=
t is not the same as good UX for a coding agent.
