Weekstart Brief · Issue 8

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:
  1. A major AI vendor changed a default: new projects now keep a copy of what your agents send. Nothing errors, so it's easy to miss.
  2. A code host started sending webhooks from new addresses. If your firewall uses a fixed list, your agents stop hearing about events.
  3. A build machine many teams still use is retired today. Jobs that ask for it fail.
  4. One AI vendor just made its cost reporting "legacy", and the new version can show which agent key spends the money.
  5. A new way to lock the add-ons your build pipelines run is now available to everyone.

This is the free teaser. Operator ($10/mo) gets the full brief and Monday checklist. Operator + Agents ($20/mo) adds the JSON pack for your agents. Issue 1 stays free.

From Issue 2 on, the public version is a teaser only. The full brief is for members.
