agy

A skill for sending reviews, adversarial reviews, setup checks, rescue tasks, status requests, and result lookups to the Antigravity CLI. Antigravity, or AGY, is a separate command-line service for these delegated tasks.

In plain words
What is it for?
Delegating code reviews, stricter code reviews, bug-rescue tasks, setup checks, job status checks, result retrieval, and cancellations.
Why use it?
It gives the coding agent a defined way to ask AGY for another review, investigate a bounded problem, or check an existing job.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agy-codex.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGY

Use this skill when the user asks Codex to use agy, Antigravity, or AGY-backed review/rescue workflows.

Invocation Contract

Prefer the MCP tools exposed by this plugin when they are available:

  • agy_setup
  • agy_status
  • agy_result
  • agy_cancel
  • agy_review
  • agy_adversarial_review
  • agy_rescue

Use the script wrapper only as a fallback when MCP tools are not available.

Resolve commands relative to this skill directory. The wrapper script lives at:

node "<path-to-this-skill>/scripts/agy-codex.mjs" <command> "<raw arguments>"

Supported commands:

  • setup checks whether AGY 1.1.1 or newer is available with the required capabilities. Use setup --smoke or MCP agy_setup with smoke: true to run a minimal implicit-stdin completion check.
  • review sends current git status and diff to AGY for review.
  • adversarial-review sends current git status and diff to AGY for a stricter review.
  • rescue delegates a bounded task to AGY. The Codex MCP tool intentionally keeps AGY sandboxing on and does not expose dangerous permission-bypass flags.
  • status shows recent AGY jobs for the current workspace.
  • result <job-id> prints captured output for a job.
  • cancel <job-id> cancels a queued or running job.

Examples:

node "<path-to-this-skill>/scripts/agy-codex.mjs" setup
node "<path-to-this-skill>/scripts/agy-codex.mjs" review "--base main security focus"
node "<path-to-this-skill>/scripts/agy-codex.mjs" rescue "--background --timeout 30s investigate the failing test"
node "<path-to-this-skill>/scripts/agy-codex.mjs" status
node "<path-to-this-skill>/scripts/agy-codex.mjs" result "<job-id>"

Safety Rules

  • Do not use shell interpolation for user text. Pass raw arguments through the wrapper.
  • Do not pass sandbox-disable or dangerous permission-bypass flags through Codex MCP. They are intentionally unavailable there.
  • Prefer foreground mode for small bounded checks and background mode for long-running rescue work.
  • Use short timeouts for smoke tests; the companion runtime gives AGY --print-timeout a grace window before enforcing its own hard timeout.
  • Treat partial jobs as timed-out print-mode runs that still captured stdout.
  • Treat rescue as no-edit by default. File changes should happen only when the user explicitly asks for edits.
  • Return companion stdout/stderr faithfully and distinguish AGY output from Codex conclusions.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agy is a skill published in the GitHub repository iicmaster/antigravity-plugins (6 stars, last pushed 10d ago), licensed MIT. It adds 37 tokens to every session and 630 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
