Love seeing this - very much what we envisioned when we launched skills. An open source community that goes beyond software developers packaging and distributing their expertise.

Prerequisite for being a global music superstar these days: cannot be afraid of heights. You're gonna be put in a harness or a slingshot and launched at the sun sooner or later.

Applications of Agent Skills is boundless. Custom CUDA kernels? Sure. Love seeing these new edges emerge. Challenging as the product marketer owning skills - how do you position a product that can do ... everything?

As PMM working on Claude Developer Platform, was critically important that we simplify prompt caching. All the intelligence, huge cost savings. Auto-caching works well with block-level so you can mix and match simple implementation and granular control.

Any day we can drop a new feature for devs and include a Wu-Tang reference is a good day. Simpler prompt caching is dolla dolla bills yall.

A statement from Anthropic CEO, Dario Amodei, on our discussions with the Department of War. anthropic.com/news/statement…

I knew I found my people and my place at anthropic! Proud of our willingness to work with the DoW to try and find a solution; proud of our willingness to stick to our principles

Who needs a bicycle for the mind when you can have skis for a thoroughbred

If it's this important, you cannot blink. Proud to continue building safe and beneficial powerful AI with this team and this leadership.

Clarity of principle and vision. Few things more American than limited government, robust civil society, and economic freedom. The beauty here is we all have a voice. Everyone should be able to use theirs without fear of retribution. 🧡

We shipped evals and benchmarking in a skill-creator update today. Write tests, A/B compare skill versions, track regressions. No code required. Whether you're a dev or an SME, you now have real tools to validate that your skills work. claude.com/blog/improving…

Give Clawd his magic wand!

Keep moving forward. Remain ready for service. Do it with equanimity. These are not normal times but they're probably the most normal it will be for a while.

Was fun working on this, looking inside the mind of Claude. Too clever at times! One thing I love about Anthropic is that no matter your role, you get deep exposure to research and product. Feeling the grain of the product helps with mission alignment.

Everyone should be creating a skill for navigating their API - with AI as the dominant mode for software development, it's such a powerful way to network best practices.

Long context generally available, no multiplier, expanded media limits - add 600 pdfs / images. If you think context rot is an inevitability, it's not. It's a problem we are working to solve with training and engineering.

🎁 Happy Friday - Opus 4.6 1M is now the default Opus model for Claude Code users on Max, Team, and Enterprise plans. Pro and Sonnet users can opt in with /extra-usage.

Really great practical guidance on skill building. The mental model for skill categories is particularly useful for people thinking through what type of skills to build!
