It's hard to overstate what Prefect 3 did for adoption. Usage has now increased nearly 10x since GA less than a year ago... and the rate is accelerating.

I was honored to open PayPal's first-ever AI Summit!
Watching a company at this scale commit to radical transformation is astounding and inspiring, and I got to see this not only from the keynote stage but in hours of conversations with the AI, LLM, and MCP teams after.

Problem solved, I guess?

It's all fun and games until an AI vibe-codes a 42,000 line PR and another AI vibe-reviews it as "impressive and substantial."
This is the way the world ends, not with a bang but a "LGTM!"

Git worktrees are the recommended way to run Claude Code in parallel, but managing them is kind of tedious... so I built claude-wt!
A simple utility to spin up and manage Claude in isolated worktrees.
No install needed: uvx claude-wt new

Copychat now includes an MCP server, so your AI assistants can quickly copy/paste source code and text.
I find it especially useful for asking Claude to write stuff directly to the clipboard.
Just add `uvx copychat mcp` as a new MCP server in your favorite client!
