Osy# · The first session

Six commands. Then your agent's turn.

From the binary to an application your agent changed and proved, with nothing installed but the one download. Every command below runs today.

The first session, 110 s. Recorded against osy 1.0.0 on 2026-09-03, unedited except for length. Every command is in the transcript beside it.
