When Seb shows a diff in chat, Apply locally writes that change directly into your working copy on disk — so you can build, run, and inspect it locally without copying the patch by hand.
Where: the Apply locally button on a diff card in chat (Agents page). Requires seb connect running on the machine with your checkout.

​
How it works

The button sends the edit to your local CLI daemon — the background process seb connect keeps running — which applies it to the file on disk.
  • Daemon offline — if seb connect isn’t running, you’ll see “Your local daemon isn’t connected — run seb connect.”
  • Branch mismatch — if your local checkout is on a different branch than the one Seb is reading, you get a heads-up before it applies, so a change never lands on the wrong branch.
  • No auto-commit — the change lands in your working tree only; you review and commit it yourself (or ask Seb to).
