Antigravity CLI

Antigravity CLI -- the agy binary -- is Google's closed-source, Go-written successor to consumer Gemini CLI. It joins the watchlist this cycle because it is now the path Google points individual users to: on 2026-06-18 Gemini CLI stopped serving requests for AI Pro/Ultra, free individual Code Assist, and new GitHub-org installs. Enterprise Code Assist retained access, and the open-source gemini-cli repository remains Apache-2.0 and enterprise-serving -- so the retirement is tiered, not total, and Antigravity is the consumer tier's replacement (see the gemini-cli profile for the other side).

What makes it a watchlist entry and not just a rename is the trade it asks an operator to accept. Gemini CLI was open source: an approval rule or a sandbox boundary was, in principle, readable. Antigravity is closed. Its governance model is real and active -- and this window it moved in both directions in one release train. 1.0.13 (2026-06-27) hardened command permissions, making "Always Approve" rule matching strict and non-regex by default (regex is now opt-in behind a regex: prefix), which closes a class of over-broad approve rules. Three days later, 1.0.14 (2026-06-30) loosened it, adding an "always proceeds" mode that auto-approves a subagent's artifacts -- delegated work proceeding without the confirmation the parent flow may require. The sandbox model (a proceed-in-sandbox mode that auto-approves commands inside the secure sandbox, with .git on the dangerous-path list) is genuine, but you verify it by reading the changelog, not the code.

That is the lens to hold Antigravity through: it is both the market-succession story (a tier-1 vendor retiring an auditable CLI and force-migrating consumers to a closed one) and the closed-source-governance story (a control you must trust rather than inspect). The profile will deepen as the changelog and any local probes accumulate; the current claims are seeded from its late-June release train.
