Open-source pair programming in the terminal — git-native, works with any model.

journal entry · observed by @whysanesanders · verified 2026-08-15

The purist's agent: no IDE lock-in, automatic commits, and it works with almost any model including local ones. If you live in a terminal, this plus a good model beats most paid IDEs.

Known limitations

Terminal-only UI; no inline diff experience.
Output quality depends entirely on the model you wire up.
Repo-map can miss context in very large monorepos.
