i wrote a deep dive on software factories in practice and how i operate mine.
if ur uncertain at all about this term, this post is for u

sharing source code for random projects in github is over
starting from scratch is often more efficient than having your coding agent start from a codebase generated by a completely different model and harness

so many gems and great tips in this talk from @yminsky about how to improve your codebase for agents
• agents thrive on feedback, and types are one of the best kinds
• make illegal states unrepresentable with types, and it enforces global rules across your codebase
• property based tests, fuzzing, and even full-system deterministic simulation testing
• expect tests: just print stuff out and capture it in the test. makes behavior legible. it's very similar to how compilers have fixture tests, it reduces the review surface area
• formal methods used to be very expensive: seL4 is about 8,700 lines of C and took around 25 person-years, with 23 lines of proof for every line of C code, but agents change the roi

@contextmode If someone engages with this post and signs up, give them unlimited credits for this week and make sure they can use Claude seamlessly without any issues.

AGNTCon + MCPCon with @nickytonline and @gethackteam 👍🏽 thanks for coming to my talk!

I'd much rather work with someone who flexes much they accomplished with the fewest amount of tokens vs how many tokens they spent, and I sense this is a major trend in general
How we quantify this as an industry is still TBD, probably a major new set of benchmarks

We automated writing code and immediately started writing 800-line instructions about how to write code
Software developers remain undefeated

Saying software is dead because anyone can build it is like saying photography is dead now that everyone in the world has a camera in their pocket
Not only is it not dead it's the beginning of the Kodak Brownie moment for software, and we will see an absolute explosion of it
It will be the first generation for who building software will feel no different than using it. This is crazy!
The quality and bar of what we expect from our everyday apps will be raised dramatically, we'll have personal software, we'll have disposable software, and agents will be the foundation for most of it
Tech has always been chaotic and evolving, the people who have been able to adapt and move in front of new opportunities have always excelled, this is nothing new, I'm seeing it now and we'll see it 10 years from now
Find the opportunities in the chaose and disruption, there are countless of them

If you want PMs and designers to build with agents, give them a starter app with your auth, design system, tests and preview deployment already wired up.
Telling people and their agents to follow engineering standards works better when they can start from a working example.

Sonnet 5.5 is out.
It gets remarkably close to Opus 5.5 on most coding and agentic work, at a fraction of the cost and noticeably faster.
Opus is still the go-to for the gnarliest, long-horizon problems. For everything else, Sonnet 5.5 is going to be hard to beat.

Stop caring so much about model releases.
Focus on the harness, and improving the environment your agent operates in.
You'll find yourself far ahead of the curve.

jev is fun to play with but you have to be careful shipping it to prod, over the past few days we accidentally racked up $3.55 in usage

we built muse from scratch, but it is definitely heavily inspired as a product by openclaw. After I used openclaw in january I bought hundreds of mac minis for the MSL team and lots of us fell in love with using openclaw (and other personal agents). @steipete is a genius and his harness was pioneering from the jump. I think a lot of people were inspired by it. our goal with muse was to build something like openclaw that we could make safe and secure and easy to use and scale to billions of people.
