Antigravity lives under ~/.gemini/ next to Gemini CLI but keeps its own subtree: config/ for the shared customization root with AGENTS.md, skills, plugins and hooks, antigravity-cli/ for the CLI's own settings, conversations, history and a SQLite summary index. Conversations are Protocol Buffers, which is why there is no session schema for it here yet.

It is the only harness with both audio and video verified: attachments go into model context natively, with documented audio formats and direct video pasting. Its binary is agy, and the headless mode is --print. No environment variable marks a session, so detection is by the .antigravitycli marker only. MCP servers use their own dialect in ~/.gemini/config/mcp_config.json. agy models lists Gemini, Claude and GPT-OSS models side by side. listModels puts all of them under google, since every one of them runs through Google's service.

Model listing runs agy models, and a filter matches the ids locally. Prints one id and display name per row, with no default marked and no filter; verified with 1.2.5.

Paths

Templates as the registry stores them. ~, ${HOME}, ${TMPDIR} and %VAR% expand in resolve(); entries tagged with a platform are dropped on the others. Open in the explorer to see them expanded for a home directory of your choice.
