Weekstart Brief · Issue 7

Get your agent stack set straight before the week starts.

Weekstart is a weekly Monday brief for people who run AI agents in production. It covers the changes that break your agents or change their costs, with what to do about each one.

This week, in short:

A major AI vendor shipped new versions of all its SDKs at once. Upgrade without looking, and settings almost every agent sends start coming back as errors.
A code host may now ask for a login on clones that never needed one. Agents that pull public code can fail with what looks like a permissions error.
An admin setting rolling out today can switch AI features and tool access on or off for anything you never configured.
A new long-lived prompt cache can cut your bill, or raise it, depending on one thing.
A popular command-line tool can now hand out tokens that expire mid-run.
