How a Team's AI Coding Flow Should Be Wired
A change lands in review with everything green. The rules pass, the types check, the tests are close to the ones I'd have asked for.

You Can't Save a Layout You Don't Own
The request was: let me arrange these panes how I like, give the arrangement a name, and hand it back to me tomorrow on a different laptop.

The Agent Will Invent the Bar
One evening an agent working in this repo killed an idea of mine for failing a rule. The kill was well argued and it cited the rule by line number, the way…

Nobody Broke It
It looks at a deprecation deadline declared in a schema, calls new Date(), compares, and if the deadline has passed it fails.

Fluent in a Dead Idiom
A newer engineer left a note on my pull request: this array should be readonly. He was right.

You Can't Grade Your Own Misses
Ask a code-review tool how good it is and you'll get a precision answer: of the things it flagged, how many were real.

Noticing Is Cheap, Judgment Is Scarce
The goal was never a cheaper reviewer. It was finding everything that is really there while posting nothing that isn't — and that objective, not the budget…

Thinking at the Speed of Code
A while back, I stopped reading the AI's end-of-task summaries and started watching the diffs. They came through faster than I could have typed them.

A Description Can't Replace the Code
A description is a compression, and it drops the omissions it doesn't know it made — the case not handled, the check not added.
