Summary

Introduces zerostack, a minimalistic coding agent built in Rust with a focus on low memory footprint (~16MB RAM) and no CPU usage when idle, aiming to be feature-equivalent to existing agents like Pi or Mistral's Vibe.

Hi everybody, I spent the last two weeks building zerostack, a coding agent in Rust, focused on memory footprint. I managed to get it to run at \~16MB (with peaks of 24MB) of RAM usage, and no CPU usage when idle. I tried to build an agent feature-wise equivalent to Pi or Mistral's Vibe, while there are plans to add more features gated at compile-time. I would love to answer questions and to recieve feedback. Cheers, G.
