Hey there, little explorer! 👋

Imagine a super-secret recipe for yummy cookies 🍪 that a company called Anthropic made. This recipe helps their robot friend, Claude, be super good at building things with computer blocks!

Oopsie! Someone accidentally dropped the secret recipe book! 😱 Now, lots of other people picked up copies, like sharing toys. Even when Anthropic tried to get the books back, some smarty-pants kids copied it into new books!

Now, other companies might learn how to make their own cookie robots. It's a bit like when your favorite toy gets copied, and everyone has one! Anthropic is a little sad because their special secret isn't so secret anymore. But don't worry, they're still making cool robots! 😊

Anthropic accidentally leaked the source code behind Claude Code. The extent of the damage is becoming clear—and it's potentially significant. The article Anthropic's leaked AI coding tool has been cloned over 8,000 times on GitHub despite mass takedowns appeared first on The Decoder .

Following the accidental leak of its AI coding tool's source code, Anthropic has had more than "8,000 copies and adaptations of the raw Claude Code instructions" removed from GitHub via a copyright request, the Wall Street Journal reports. One programmer already used AI tools to rewrite the code in different languages, keeping it available despite takedowns. This shows just how damaging a code leak is in the age of AI: once it's out, it spreads faster than anyone can contain it.

The code contains valuable techniques Anthropic uses to control its AI models as coding agents—the "harness"—including a "dreaming" function for task consolidation. Competitors now have a blueprint to replicate Claude Code's capabilities, weakening Anthropic's edge in an already cutthroat market.

The timing is particularly bad: the company is planning an IPO at a $380 billion valuation, and this kind of leak is unlikely to sit well with investors. It also comes just days after a separate leak about Anthropic's new AI model Mythos, also caused by human error within the company's content management system.
