agy-native

Drive the AgentOps loop on the Antigravity image (AGY): the agy CLI backed by the brain/knowledge store at ~/.gemini/antigravity-cli/. This is the third harness alongside the Claude image and the Codex image — same loop laws, AGY-native primitives. Invoke agy, never rebuild it.

Overview / When to Use

AGY is Google's Antigravity agent harness exposed as a local CLI (~/.local/bin/agy). It speaks the Claude-style packaging shape (plugins, skills, subagents, hooks, MCP) and a portable SKILL.md — AGY reads skills from ~/.gemini/skills/ directly, so the AgentOps corpus already loads on it. Use this skill when you need the claim->work->validate->close->persist loop running on AGY (driving Gemini, or Claude/GPT models through AGY — agy models exposes Gemini 3.5/3.1, Claude Sonnet/Opus 4.6, GPT-OSS), as a parallel or fallback to the Claude/Codex images.

AGY ≠ gemini-cli. The retired gemini CLI lane (gemini -p, gemini skills, gemini extensions, --approval-mode, --worktree) is gone. Everything here is an AGY affordance; §"Distribution" + the reference file name each AGY equivalent for an old gemini habit.

Verified primitives on this host (agy --help, agy plugin help, agy models):

• Headless run: agy -p "<prompt>" / agy --print (one-shot, prints, exits; --print-timeout default 5m). -c/--continue resumes the most recent conversation; --conversation <id> resumes by ID.
• Plugins: agy plugin {list,import,install,uninstall,enable,disable,validate,link}. import [gemini|claude] pulls existing plugin trees in. install <target> reads a plugin.json (supports plugin@marketplace).
• Permissions: --dangerously-skip-permissions auto-approves tool calls (loop/headless lane); --sandbox restricts the terminal.
• Workspace scope: --add-dir <dir> (repeatable) scopes which repos a run can touch (AGY's write-isolation primitive — it scopes by directory, not by spawning worktrees).
• Brain/knowledge: durable agent memory + user-facing artifacts under ~/.gemini/antigravity-cli/{brain,knowledge}/ (per-conversation dirs; *.md + *.md.metadata.json with {summary, updatedAt, userFacing}).
