# HarnessLink 17.11.0 release notes 2 changes, released Nov 8, 2026. ### Added - **Antigravity counts through the gateway on a Gemini API key.** A new `gemini` gateway route (`https://generativelanguage.googleapis.com`) takes Antigravity CLI's Gemini API calls: the model comes from the request path (`…/models/:generateContent` or `:streamGenerateContent`), usage maps `usageMetadata` (cached prompt tokens as cache reads, thinking as output; streamed chunks are cumulative, the last wins), org model rules match `gemini/`, refusals come back in Google's error shape so `agy` shows them, an API key sent as `?key=` never enters a cache key, and compression touches only Gemini text parts and function responses. `hnl gateway connect antigravity` works when Antigravity runs in Gemini API-key mode (`"modelProvider": "gemini"` in `~/.gemini/antigravity-cli/settings.json`): it exports `GOOGLE_GEMINI_BASE_URL` for new terminals in a marked block in `~/.zshrc`, `~/.bashrc` (and an existing `~/.bash_profile` on macOS) or `~/.config/fish/conf.d/hnl-gateway.fish`, or as a Windows user variable, refuses when the variable already points elsewhere, and `disconnect` removes exactly that block. Signed in with a Google account, Antigravity's calls still go straight to Google: `connect` changes nothing and says how to switch, `hnl gateway connect` with no harness named skips it, and `hnl gateway status` shows which mode it is in. ### Fixed - Usage's "Models from … aren't in this table" notice listed the old HarnessLink agent as a harness and told you to run `hnl gateway connect superpi` and `hnl gateway connect antigravity`, neither of which can work, and its text ran two words together ("sotheir"). The old built-in agent is no longer a harness: usage coverage leaves it out entirely. Antigravity is named with the reason it can't be counted (its signed-in traffic goes straight to Google), and commands are offered only for harnesses the gateway can route (Claude Code, Codex, omp, pi).
