Every engineer can generate code with AI now. So that's no longer your edge.
What actually separates the engineers who thrive from those who don't?

94 points on evals from a single change 💰
The secret? Your evals should reflect exactly what your model sees in production. That's it.
Not a clever trick. Just good engineering.

Most people don't know how much control you have over Claude Code skills. ⚙️
• Pin a specific model to a skill
• Disable model invocation and keep it local
• Pass arguments inline
• Make a skill non-user-invokable so it only runs automatically
This is the kind of control that makes it actually fit into a real workflow.

AI agents are great at writing code but terrible at knowing if it works.
Playwright fixes the second half. End-to-end tests that agents (and humans!) can act on.

Evgenii Ray has used AI since the very first models. And even he's surprised by how fast it's improved. Two years ago it struggled with complex code. Now it actually understands patterns. That's not a small jump.

Managing Anchor Associations With Data Attributes and Advanced attr()
There is no `anchor` attribute in HTML, it was decided CSS `anchor-name` / `position-anchor` was the way to go. But modern CSS functions can get us there anyway.

The barrier to querying your own data is almost gone.
Front-end devs can now load their Google Analytics into DuckDB, ask "which browsers have the most latency?" and get the answer.
You don't need a data scientist for every question anymore. You just need to know what to ask.
