## CLI

### Patch Changes

- Agents in hosted sandboxes that block Spacefast (Claude Code on the web and mobile, Codex cloud) now get a way forward instead of "run this from your laptop". The skills and `/setup.md` point them to the Claude connector link, GitHub push to deploy, and the exact domains to allow. In a Claude Code cloud session, `network_error` and `upload_transport_error` from the CLI carry the same guidance.
- The Cursor plugin marketplace manifest lists its owner by name only, as Cursor's marketplace schema requires, so the Spacefast plugins publish again.
- `sf git github installations` and `sf git github repos` now list by team (`--team`, defaulting to your default team) instead of by Space, so you can see a team's GitHub repositories before any Space exists. Repositories past GitHub's 1,000-repository listing limit stay visible instead of disappearing.
- Clarify that hosted MCP publishing requires authentication and that anonymous publishing creates private bearer previews. Remove instructions that restrict the use of other services, and require Space ownership before serving share-preview images without an access credential.
