Antigravity (agy) was wired into the session layer but never propagated to
the surfaces around it, while Gemini CLI stayed documented as a consumer
product despite being enterprise-only since Google's cutover. Gemini keeps
full support; Antigravity now sits beside it everywhere.
Functional fixes:
- docker/agent.Dockerfile never installed agy, so a docker case with
mode 'antigravity' died on command-not-found. agy is not on npm, so it
gets its own installer step. --dir /usr/local/bin is load-bearing: the
default $HOME/.local/bin resolves to root's home at build time and is
unreachable by the `agent` user the container runs as. Verified inside
codeman/agent:base (v1.1.10, reachable as `agent`). Note the binary is
~190MB, the largest layer in the image.
- Welcome screen gained a Run Antigravity action, gated on agy being
present like the other CLI buttons, with a cyan identity matching the
toolbar run button and run-mode dot.
- install.sh now detects agy (search paths mirroring the resolver), counts
it as a satisfying AI CLI, and recommends it over Gemini in the install
hints. Detection only, no new auto-install path.
Docs corrected where they were factually wrong:
- architecture-invariants documented isExternalCliMode() as
opencode/codex/gemini when the code has included antigravity for a
while, said "all three modes", and omitted ANTIGRAVITY_ from the env
prefix allowlist row.
- cron-guide's agentType enum, cron-discovery's SessionMode, and
remote-sessions' RemoteCommandMode were all stale.
Also: README + README.zh-CN (five CLIs, Gemini marked enterprise-only),
package.json keyword, and comment drift in 8 places.
test/run-mode-ui.test.ts now covers the new welcome button; verified it
fails without the settings-ui wiring.
Antigravity nests its whole state under ~/.gemini/antigravity-cli/, not
~/.antigravity, so the existing .gemini docker credential seed already
covers it. Recorded as a comment so nobody adds dead config later.
isAltScreenStripMode() deliberately still excludes antigravity: whether
its TUI needs the alt-screen strip is a behavioural question that needs a
real agy session, not a guess.
