Hi, I'm Jalmari.

I build teams of AI agents at Parvi, mostly for marketing and sales work. I spent 12 years in digital marketing, and in spring 2026 Claude Code turned my work upside down in a single day. This is where I write up what I build with it, including the parts that broke and how I fixed them.

Claude Code deletes your chats after 30 days
Claude Code deletes chats older than 30 days by default, with no warning. One line in ~/.claude/settings.json keeps them. I'm still testing it.
