Why it was accepted

The page clearly describes a real AI developer tool with a concrete workflow: one session, two model CLIs, local session syncing, and instant switching between Claude and Codex. The README shows installation, quick start steps, command examples, and an explanation of how the syncing works, which is enough for a useful public listing.

Weakness

The crawl does not show release history, tests, screenshots, or maintenance signals beyond the repository contents. It also does not show how well the tool handles edge cases like session conflicts, unsupported CLI versions, or failure recovery.
