Antigravity CLI

See the generated compatibility matrix for capability details and version-scoped evidence.

antigravity-cli integrates Google's Antigravity CLI (agy) into ctrlyoke.

Use it when:

• You want Google's current CLI path for coding workflows
• You need Antigravity model choices such as Gemini Flash, Claude, or GPT-OSS
• You want ctrlyoke workflow execution, MCP, agents, skills, and history around agy

harness: antigravity-cli
model: gemini-3.6-flash-low
steps:
  - prompt: Update the implementation and run the focused tests.

Notes:

• Install and authenticate agy before selecting this harness.
• ctrlyoke requires agy 1.1.12 or newer.
• Permissions are coarse modes only: dangerouslyAllowAll passes --dangerously-skip-permissions, custom passes --sandbox, and allowAll passes nothing, so agy applies its own approval behavior. allowedTools / deniedTools are not enforced, and MCP servers cannot be filtered per tool. Image references are not attached.
• Only the preToolUse, postToolUse, sessionStart, and stop hook events fire; userPromptSubmit, permissionRequest, notification, and error do not.
• MCP servers are written to the workspace .agents/mcp_config.json, which agy discovers on its own. There is no per-prompt server scoping, so parallel workflows in one workspace share that file's servers.
• ctrlyoke's hooks go in ~/.gemini/config/hooks.json and its statusline in ~/.gemini/antigravity-cli/settings.json; ctrlyoke restores both files when the run ends.
• ctrlyoke's default Antigravity model is gemini-3.6-flash-medium, not agy's own Claude Sonnet default.
• Models are the IDs agy models prints (gemini-3.6-flash-low, claude-sonnet-4-6, …). The dashboard shows agy's friendlier labels ("Gemini 3.6 Flash (Low)"), and agy itself accepts either spelling, but workflow files and settings use the ID.
• For manual test runs, prefer a Gemini Flash tier to avoid exhausting the much smaller Claude quota.
• Antigravity stores some user-level config under ~/.gemini/; those paths are expected and are not Gemini CLI support.
