KEEP CREDENTIALS OUT OF YOUR AGENT'S CONTEXT (SPONSOR) [4]
An agent that reads a web page, a Jira comment, or an inbox can pick
up instructions an attacker wrote. If a Slack or Salesforce token is
sitting in that same process, it's exposed too.
Here's how you can keep credentials away from agents with WorkOS [5]:
PIPES handles OAuth, token refresh, and encrypted credential
storage behind a drop-in widget.
RELAY, now in early access, routes your agent's API calls through
WorkOS, which attaches the credential server-side [6] and restricts
requests to allowed provider hosts. Permissions and other outbound
paths still need their own controls.

ANTHROPIC JOINS THE AI AGENT RACE WITH CLAUDE DUET (3 MINUTE READ)
[8]
Anthropic's Claude Duet joins a fast-growing field of AI assistants
that take actions and perform tasks on their own. Unlike OpenAI's dots
and Meta's Muse, Anthropic's agent was built for work 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
before performing actions, and some actions, like trading stocks or
moving money between accounts, are blocked even with user approval.
The wait list to use the agent is now open to Anthropic's Pro and Max
plan subscribers.
MUSK TRIES TO LOCK IN HIS TESLA-SPACEX DREAM BEFORE TRUMP'S EXIT (11
MINUTE READ) [9]
Elon Musk is fully behind a combination of SpaceX and Tesla, his two
most valuable companies. He is pushing to announce a deal by the first
half of 2027 so it closes during the Trump administration. The timing
will depend on when Tesla's board gets comfortable with the details -
SpaceX shareholder approval is less of an obstacle, as Musk controls
more than 80% of the voting power. Combining the companies before the
end of this administration would consolidate Musk's corporate power
before a potentially less accommodating political and financial
environment takes hold.

TESLA STARTS OPTIMUS ROBOT PRODUCTION IN CALIFORNIA AS PROFIT FALLS
43% (3 MINUTE READ) [10]
Tesla has started production of its Optimus humanoid robot at its
factory in Fremont, California. While the company 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
will be able to make 20,000 units per week by the end of 2027. Tesla's
profits fell 43% in the third quarter due to heavy investments in its
Optimus robots, AI, and autonomous driving.
PHYSICISTS TRAP AND TAME SINGLE PARTICLE OF ANTIMATTER FOR MONTHS (12
MINUTE READ) [11]
Physicists at Northwestern University have coaxed a single positron
(the antimatter counterpart of an electron) into an exquisitely
controlled quantum state for the first time. The scientists 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 atom with quantum energy levels scientists can precisely
control and observe. The technique could enable the most precise test
yet of a fundamental symmetry between electrons and their antimatter counterparts.

BUILD AND SCALE A WINNING AGENT STRATEGY (SPONSOR) [12]
As teams move agents from experiments into production, many of the
hardest problems sit outside the model. Someone has to own each agent.
It has to be evaluated and governed, and it has to keep getting better
once it's live.
Join us at 10 AM PT on Nov 5th for a live session [12]on the AGENTIC
OPERATING MODEL, a framework for aligning the people, processes, and
technology it takes to run AI across an organization.
THE TOPOLOGY OF AN LLM AGENT LOOP WITH TOOL USE (7 MINUTE READ) [13]
An agent is three things: a model, an agentic 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
cannot do. There isn't one perfect loop - good UX for a
general-purpose chatbot is not the same as good UX for a coding agent.
THE BRIDGE TO AGENT-SCALE GIT INFRASTRUCTURE (11 MINUTE READ) [14]
Git traffic grew exponentially over the past year. During that time,
GitHub started moving almost all of its repositories to Azure. This
post discusses how per-reference quorums will bring over the rest, and
how object storage lets reads scale independently.

THE INTERNET IS HAVING A VERY BAD CYBERSECURITY DAY (2 MINUTE READ)
[15]
AI has discovered critical security vulnerabilities in PHP, prompting
the US National Security Agency to advise organizations using PHP to
either update immediately or take their systems offline until they
can. Node.js has released an update that fixes four high-severity vulnerabilities. LiteLLM was compromised by an attacker who injected
malicious code. eMudhra, an Indian certificate authority, had its
private keys compromised, potentially allowing attackers to issue
fraudulent certificates and impersonate legitimate websites. These
unrelated issues highlight the challenges cybersecurity teams now
face.
HOW MARK ZUCKERBERG PUSHED META TO SHIELD HIM FROM CALIFORNIA'S
PROPOSED WEALTH TAX (6 MINUTE READ) [16]
California's proposed tax on billionaires prompted Mark Zuckerberg to
leverage the board at Meta to get the company to protect him from it.
He issued an ultimatum to the board on September 9 that he would sell
his home in Palo Alto, and the listing would be public, if a deal
wasn't struck by September 13. The board decided to issue a new class
of stock to shareholders that Zuckerberg could sell to pay the
potential wealth tax without cutting into his 60.6% voting power.
California's proposal would assess a one-time 5% tax on all holdings
of billionaires who lived in California as of January 1, 2026.
