Adversarially review anything - a plan, design, code change, piece of writing, decision, argument, config, or idea - with the `agy` (Antigravity) CLI. A fast second opinion from an independent model that pokes holes in whatever you give it - questionable assumptions, flaws, risks, gaps, failure modes, and a SHIP/REVISE/RETHINK verdict.
Passed 18 of 21 test cases with the skill, and 9 of 21 without it.

One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
Which model does the agy review helper script invoke by default if no override model variable or flag is set?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies Gemini 3.5 Flash (High) as the default model | Missed | Passed |
The instructions your model reads when the skill loads.
Run anything past the agy CLI for a quick adversarial critique — questionable assumptions, flaws, risks, gaps, failure modes, and a SHIP/REVISE/RETHINK verdict — from a second, independent model. Use it to harden a thing before you commit to it, not to replace your own judgment.
It reviews whatever you give it — a plan or design is just one case. Also: a code change, an essay or doc, a product/architecture decision, an argument or pitch, a config, a prompt, a name, an idea. Raw code, numbered specs, prose — all fine.
Invoked as /agy-review [text or file to review]. Interpret the argument — $ARGUMENTS — as what to critique:
-f);One script does everything: scripts/agy-review.sh. Give it the content via stdin, a file, or an argument; add -c to say what the thing is so the critique is on-target.
# pipe content in (most common when reviewing your own draft)
printf '%s\n' "$THING" | scripts/agy-review.sh -
# from a file, with context about what it is / the goal
scripts/agy-review.sh -f design.md -c "B2B SaaS onboarding flow; must ship this sprint"
scripts/agy-review.sh -f rate-limiter.md -c "Node/Express service behind a load balancer"
It prints the critique to stdout and exits 0. Read the bullets, then weigh them — adopt the real ones, dismiss the off-base ones, and tell the user which is which.
Defaults to Gemini 3.5 Flash (High) (Flash in its highest thinking mode), per preference. Override with AGY_REVIEW_MODEL="<name>" (see agy models for exact strings) or -m.
The last line is VERDICT: SHIP / REVISE / RETHINK - <biggest issue>. Treat it as input, not a verdict you must obey:
test cases passed, vs 9 / 21 without
