I use Pi and love it, but the base install is extremely minimal (a handful of tools, no subagents, etc.). That’s on purpose. Sure, you can add more with packages, but that’s not the base install.

The main ones missed immediately were web access/search. Then the to-do list features (it was a nice surprise to try OpenCode and see this working immediately.). There were a couple of other niggles but it was a few months ago. Also, this may not be common, but it seemed to struggle to edit effectively (driven by Qwen 3.6 35b/27b) and often rewrote whole files instead.
