ANTHROPIC WANTS CLAUDE TO BE YOUR NEW SLACK COWORKER (2 MINUTE READ)
[6]
Claude Tag is a new feature that lets users create a chatbot that
interacts on their behalf on Slack. It can be used to monitor Slack
activity, send alerts about important posts, drop comments in
conversations, and fix issues with code. Claude Tag will replace the
existing Claude Slack app. It is being rolled out to Anthropic's
enterprise and team subscription users.
MARK ZUCKERBERG DIRECTED META TO CREATE A PREDICTION MARKETS APP (6
MINUTE READ) [7]
Mark Zuckerberg recently dispatched a small team at Meta to create a smartphone app similar to Polymarket and Kalshi. The app uses a points
system rather than real money, but Meta has not ruled out the eventual
use of real money betting. Internally referred to as 'Arena', the app
will function independently from Meta's other apps. The effort is part
of a broader purchase at the company to create new types of apps based
on emerging social behavior online.

WITH STARFALL, SPACEX EYES AN EDGE IN GLOBAL CARGO DELIVERY FROM
ORBIT (3 MINUTE READ) [8]
A SpaceX Falcon 9 rocket lifted off yesterday with a new
saucer-shaped reentry pod called Starfall. The secretive mission's
purpose is reportedly to support the transport and delivery of goods
through space. Most of what is known about Starfall comes from the
FAA's environmental assessment, which says that Starfall will enable point-to-point delivery of critical cargo through space on rapid
timelines and provide access to space for commercial in-space
manufacturing. Starfall is designed exclusively for cargo and is
smaller than SpaceX's human-rated Crew Dragon spacecraft.
WAR BY OTHER MEANS (18 MINUTE READ) [9]
The use of robots in war will only increase. All signs point towards governments relying on a much smaller pool of human capital for labor
and war. The use of unmanned munitions drives down costs and lessens
the need for humans on the battlefield without weakening deterrence.
This means that a fundamental source of political power has begun to
shift from the people towards the firms that make the machines.

AGENT STUCK ON A CAPTCHA? BROWSERBASE LOGS IN, NAVIGATES, AND
FINISHES THE JOB. (SPONSOR) [10]
CAPTCHAs and login walls are where most agents quit. Browserbase
gives yours a browser that can sign in, get past the block, and carry
on—on any site. It's self-healing when pages change and scales to
thousands of concurrent sessions, which is how 10K+ teams, including
Ramp and Lovable, run 35M+ sessions a month.

THE COMING LOOP (16 MINUTE READ) [13]
Agent loops are enabling teams to build at astonishing speeds.
However, their use reduces developers to the role of merely a
messenger. Looping is powerful, but it removes responsibility and
encourages people to give in to the machine. While agent loops are
likely going to be the future, it's important for developers to retain
good judgment and ensure the rules of good engineering are kept.
THE PROBLEM IS PROMPT DEBT (8 MINUTE READ) [14]
Treating natural language as a specification language for engineering
quietly caps what you can build. Prompt debt increases as additional
guidance is added to instructions to nudge models into line. These
prompts, full of edge cases and threats to the AI, become impossible
to comprehend for teams. Prompt debt locks developers into older
models, possibly making them miss potentially cheaper, faster, and
better models.

NSA LOST ACCESS TO POWERFUL AI MODEL AMID ANTHROPIC DISPUTE (6 MINUTE
READ) [17]
NSA cybersecurity analysts were testing versions of Anthropic's tools
when export controls were imposed on the company. The tests found that
Mythos was able to identify cybersecurity flaws within the NSA's
classified network quickly. Analysts were impressed with Mythos'
capabilities in controlled test settings. There is an effort to push
forward a classified contract between Anthropic and the NSA that would
allow the agency to use the company's AI technology for a variety of
purposes, but that contract has not been finalized.
DEAD PLAYERS (8 MINUTE READ) [18]
Founders used to aim for the stars. iPhones, social networks, large
language models, and cryptocurrency are the sort of non-linear
increments that were either created by accident or in the process of
trying to do the impossible or unprecedented. The non-linear option is
now more impersonal and lower-risk than ever. This means people who
have no personal reason to take risks and pursue a moonshot are more
likely to try anyway.
