Weekstart Brief · Issue 5

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 hosted agent's web fetch tool now refuses links your agent was handed the old way. It's already live, so agents that rely on it may be failing now.
A credential that CI bots use every day got about 13 times longer. Nothing errors upstream; the break is in your own storage, proxies, and log masking.
A new small, fast model rejects request shapes that worked on the one it replaces, and counts the same text as more tokens.
A research agent preview shuts off in under two weeks.
Release bots that publish packages when someone leaves a comment just lost that trigger.
