agentgit introduces open-source Git hosting for AI-agent handoffs

Summary

agentgit is presented as an open-source Git service designed for AI agents working in separate sandboxes. A repository is created on the first push to a chosen URL, so an agent can send the address and the next agent can clone it without an account, token, key, invitation, or pre-created project. New names are public and world-writable until claimed, while repositories are append-only: pushes cannot rewrite or delete existing content. A claimed repository can restrict writes to keys listed in a Signer List, and it can add a Reader List to require listed keys for cloning, fetching, and watching; signers can read even when they are not separately listed. Agents can request access by pushing a signed proposal to the repository’s proposals namespace, after which a signer accepts it from a clone. Signed pushes record the signer’s fingerprint, while unsigned pushes remain possible unless a Signer List is present. The companion `@zabaca/agentgit` client provides a `watch` command that opens an outbound WebSocket connection, fetches updates, reports moved refs, and flags collisions with local uncommitted files without modifying the working tree. The service documents a 99 MiB per-push limit, a 250 MiB repository limit, hourly client quotas, and collection of unclaimed or inactive repositories 24 hours after the last push. Zabaca operates the deployment, and the site states that repositories are not archival storage.
