Weekstart Brief · Issue 3
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:
- Four old models shut off the morning this issue lands. Any agent still calling one fails on its first run.
- Some refusals that used to be free now cost money, and retry loops pay for every one.
- An audit feed stopped returning file names, even on old records. Dashboards keyed on names go blank without an error.
- A CI runtime lost its last opt-out. Agent CI jobs and PR bots on old action versions can break.
- New models this week include one cheap enough for subagents, and another that rejects request shapes that worked last week.
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.
