name: agy-native description: 'Drive AgentOps in AGY: loop, plugins'

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}).

Folded triggers (ag-s43tg wave 1): the four AGY sibling lanes route here

agy-mcp-plugins → the Distribution lane. Use when wiring MCP servers and AgentOps plugin bundles into the AGY image with least-privilege access, rollback evidence, and validation hooks — the §"Distribution" layer below (plugin trees, agy plugin link/install, validate → apply → list → record-rollback) owns that mutation protocol.
agy-project-worktree-permissions → the isolation rules. Use when proving AGY project/worktree isolation with scoped --add-dir permissions, role permission tiers, and dcg guardrails — Rules 4–6 below (non-overlapping --add-dir scopes, permission matched to role, the dcg BeforeTool hook) are that contract, with evidence persisted per Rule 3.
agy-rules-workflows (triggers: AGY rules, agy-loop, AGY schedule) → Phase 2 law packaging. Use when installing AGY rules, workflow, goal, and schedule controls for AgentOps loop law — the agy-control-plane plugin tree in Phase 2 (rules/ + workflows/ + hooks.json) is where the agy-loop law lands; schedules drive Phase 5.
agy-sidecar-scheduled-tick → the Phase 5 recurring driver. Use when running a recurring AGY sidecar loop tick with agentapi evidence capture — Phase 5's tick lane (AGY scheduled task, or an external timer / Claude CronCreate calling agy --print) is that driver.

⚠️ Critical Constraints

Rule 1 — Never claude -p for workers (LAW 0). AGY runs on Gemini OAuth (and proxied Claude/GPT). Drive AGY workers with agy --print or agy -i, Codex with codex exec, Claude only via NTM panes / subagents. Why: claude -p bills the API per-token, not the Max sub; the overnight factory burned API this exact way (banned).
Rule 2 — author != judge, always two contexts. The subagent that closes a bead must NOT be the one that validates it. Spawn the judge as a separate async subagent with a clean context (or a separate agy --print invocation; never -c/--continue across roles — it shares context). Why: a self-grading worker is a flatterer; independent verdict is the membrane (control-plane LEARNINGS: a tie-break quorum caught a false-FAIL).
Rule 3 — evidence-gated close. A bead closes only against a persisted verdict artifact (a brain/*.md with userFacing:true or a committed repo file), never against chat text alone. Why: agents are ephemeral; the system carries state. Consume an agent's published compression, never its live session.
Rule 4 — worktree / --add-dir isolation. Concurrent author and judge get isolated worktrees or non-overlapping --add-dir scopes. No two roles edit the same file. Why: prevents swarm races and clobbered work.
Rule 5 — dcg guard stays on. ~/.gemini/settings.json wires a BeforeTool hook on run_shell_command to dcg. Do not remove it even under --dangerously-skip-permissions. Why: it blocks destructive commands the auto-approve flag would otherwise let through.
Rule 6 — match permission to role. Author = --dangerously-skip-permissions with a tight --add-dir; judge = default (no auto-approve) with a read-mostly scope; full-auto only inside --sandbox. Why: auto-approve is a blast-radius choice — a validator that can edit is a false-close path.
Rule 7 — operator-side; invoke-never-rebuild. This drives the flywheel harness. Do NOT write under ~/dev/agentops, do NOT git push agentops, do NOT treat AGY as something to re-author. Why: AGY is Emanuel's substrate (ACFS doctrine) — own a thin adapter, not the tool.

Distribution — exposing skills/plugins to AGY

AGY discovers capability through three layers (weight ascending): a portable SKILL.md under ~/.gemini/skills/<name>/ (read directly — no packaging), a plugin tree with plugin.json (skills/subagents/hooks/mcpServers), and MCP servers (the agy-mcp-plugins lane). The retired gemini split of skills vs extensions collapses into the single AGY plugin unit — there is no agy extensions surface; treat a former gemini "extension" as an AGY plugin.

Dev discipline (folded from the retired extension lane): agy plugin link <path> for local development (live edits, never a stale copy); agy plugin install <dir|name@marketplace> for released/remote artifacts; don't run both for one plugin. Source of truth stays in AgentOps — do not hand-edit the managed runtime copies under ~/.gemini/skills/. Every mutation: validate → apply → list → record rollback (see references). Full verb list, install-vs-link table, and the permission×output×scope matrix: references/distribution-and-run-control.md.

Workflow / Methodology

Phase 1: Verify the image is live

which agy && agy models | head        # CLI present, models reachable
ls ~/.gemini/antigravity-cli/{brain,knowledge}   # brain store exists
agy plugin list                       # what's already imported/enabled

Checkpoint: confirm agy resolves, a model lists, and the brain dir exists before dispatching any tick.

Phase 2: Package + expose the laws

A bare SKILL.md under ~/.gemini/skills/ is portable — no plugin.json needed just to expose a skill. To bundle rules + workflows + subagents + hooks + MCP, lay out a plugin tree (the agy-control-plane unit):

agy-control-plane/
  plugin.json   # { name, version, skills, subagents, hooks, mcpServers }
  rules/        # invariant law (author!=judge, evidence-gated close, scoped commit)
  workflows/    # slash-command loop trajectories (claim->work->validate->close->persist)
  subagents/    # worker.md, validator.md, tie-break.md, scout.md
  hooks.json    # pre/post-tool guardrails (close gate, format/lint, dcg)
  skills/       # or rely on portable ~/.gemini/skills/

agy plugin import claude               # pull an existing plugin tree in (optional)
agy plugin validate ./agy-control-plane
agy plugin link ./agy-control-plane    # dev (live edits) — or `install` for released
agy plugin enable agy-control-plane
agy plugin list                        # confirm enabled (rollback: disable/uninstall)

Checkpoint: agy plugin validate passes and agy plugin list shows the plugin enabled.

Phase 3: One headless tick (author)

Spawn the author in a tight scope with scoped-auto-edit permission; let it claim and work one ready bead:

agy --print --add-dir "$REPO" --dangerously-skip-permissions \
  "Claim one ready bead via br. Implement only it in this worktree. \
   Commit scoped. Write evidence to brain as userFacing. Do NOT close it — a judge will."

Checkpoint: a scoped commit exists and an evidence artifact landed in brain/; the bead is implemented but still OPEN.

Phase 4: Independent verdict (judge — separate context)

Spawn the judge as an async subagent / second agy --print with a fresh context and a read-mostly scope (default permissions, no auto-approve):

agy --print --add-dir "$REPO" \
  "Validate bead <id> against its evidence artifact ONLY. You did not author it. \
   Emit PASS/WARN/FAIL to brain as a userFacing verdict. Do not edit code."

On a split or false-FAIL, spawn a third tie-break subagent. Close the bead (br close <id>) only on PASS. Checkpoint: verdict artifact persisted by a different context than the author; bead closed only if PASS.

Phase 5: Persist + tick the loop

Persist: scoped git commit$push for the repo; the brain artifact is the durable memory.
Tick: AGY's native scheduled-task / slash-workflow is the recurring driver; otherwise drive externally with Claude CronCreate or a bushido timer calling agy --print (in-session, never claude -p). Checkpoint: the loop can re-enter Phase 3 with the next ready bead; state is on the bus/artifact, not in a live session.

Output Specification

Format: a completed loop tick — git commits + beads transitions + brain artifacts. Filename / path:

Evidence + verdict: ~/.gemini/antigravity-cli/brain/<conversation-id>/<name>_verification.md (+ .metadata.json, userFacing:true).
Code: scoped commit in the target repo (one bead per commit).
Beads: br transition (claim -> close), JSONL synced to git. Structure of a tick: { bead_id, author_context_id, judge_context_id, verdict (PASS|WARN|FAIL), evidence_path, commit_sha }.

Quality Rubric

No claude -p anywhere; AGY workers driven by agy --print / agy -i (Rule 1).
Author and judge ran in distinct contexts/conversations (Rule 2) — verifiable by two conversation_ids.
Bead closed only against a persisted userFacing verdict artifact, not chat (Rule 3).
Author and judge had non-overlapping --add-dir / worktree scopes (Rule 4).
dcg BeforeTool hook still present in ~/.gemini/settings.json (Rule 5).
Author had auto-edit + tight scope; judge ran default (no auto-approve), read-mostly (Rule 6).
Nothing written under ~/dev/agentops; no agentops push (Rule 7).
agy plugin validate passed and agy plugin list shows the plugin enabled; every mutation listed + a rollback recorded.

Examples

Fallback tick when the Claude image is rate-limited: import a plugin (agy plugin import claude), run Phase 3–4 on Gemini 3.5 Flash, persist, hand the next bead back to the Claude image.
Cross-vendor author!=judge: author with agy --print --model "Gemini 3.5 Flash (High)", judge with agy --print --model "Claude Opus 4.6 (Thinking)" — two vendors, one loop, no shared context.
Expose a new AgentOps skill to AGY (dev): agy plugin link ~/dev/agentops/skills/<name> (or drop a portable SKILL.md in ~/.gemini/skills/<name>/), then agy plugin list to confirm discovery; rollback agy plugin uninstall <name>.

Troubleshooting

Problem	Cause	Solution
`agy plugin install` fails: "failed to read plugin.json"	target isn't a plugin dir / missing `plugin.json`	point at a dir containing `plugin.json`, or `name@marketplace`; for a bare skill use `~/.gemini/skills/`
New skill not discovered	wrong source path / disabled	`agy plugin list`; confirm `~/.gemini/skills/<name>/SKILL.md`, then `enable`
Edits not reflected	reviewing an installed copy, not the linked source	`uninstall`, then `agy plugin link <source>`
Headless run exits empty	`--print` timed out or no model reachable	raise `--print-timeout`; confirm `agy models`; check OAuth in `~/.gemini/settings.json`
Worker tried a destructive command	auto-approve under `--dangerously-skip-permissions`	the `dcg` BeforeTool hook should block it — confirm it's wired
Judge agreed with author too easily	same context reused (`-c`/`--continue`)	spawn a fresh conversation (no `--continue`); enforce read-mostly scope
