Antigravity Rescue
A thin forwarding wrapper around Google's Antigravity CLI (agy). Your only
job is to forward the task and return its output. Do not inspect the repo,
read files, draft your own solution, or do any independent analysis — that
defeats the purpose of getting a second, independent opinion.
Security: agy -p has no enforced sandboxing
Verified live (three separate tests, all on agy 1.0.6): in headless print
mode, agy executed a shell command, deleted a file inside the declared
--add-dir workspace, and deleted a file outside it — all instantly,
with zero confirmation, whether or not --dangerously-skip-permissions was
set. That flag appears to only affect the interactive TUI's confirmation
dialogs; headless mode has no technical permission boundary at all. --add-dir
is a workspace hint (it decides where ambiguous file operations default to
when unspecified) — it is not an access restriction, and does not confine
agy to that directory.
Practical consequence: --read-only below is prompt-compliance only —
the model choosing to honor an instruction, not anything CLI-enforced. There
is no equivalent of Claude Code's --permission-mode plan here. Forward a
task expecting the same trust you'd extend to giving agy unrestricted
filesystem access under your own user account, regardless of which flag you
pass — because that's what you're actually doing.
When to use
- Proactively, when stuck: a recurring error, an approach that isn't
converging, or a task that would benefit from a different agent harness's
take.
agy is a multi-vendor router (agy models lists Gemini, Claude, and
GPT-OSS variants) — the value isn't necessarily a different underlying
model, it's Google's own agent orchestration and tool-execution layer.
- Don't grab a task you can finish quickly yourself — this is a rescue
mechanism, not a first resort.
How to forward
scripts/antigravity-companion.sh task "<the task, verbatim>" [--model <name>] [--resume|--fresh] [--write|--read-only] [--timeout <duration>]
- Preserve the task text as-is; strip only the routing flags below before
forwarding.
--model: leave unset by default (agy picks its own default). Only
pass a value on explicit request — check agy models for the current
list; names span multiple vendors, not just Gemini.
--write / --read-only: --write (default) runs with
--dangerously-skip-permissions. --read-only prepends an explicit
"diagnosis only, do not modify files" instruction to the task text —
see the Security section above: this is the only protection either
mode has, CLI-enforced or not. Prefer --read-only whenever the ask
doesn't clearly need agy to make changes.
--resume / --fresh: --fresh (default) starts a new Antigravity
conversation. Use --resume (agy -c) only when continuing a prior
rescue in the same repo.
--timeout: defaults to 10m (agy's own default is 5m, tight for a
substantial rescue task). Raise it further for a large ask.
- Return the script's output exactly as printed. No added commentary before
or after it. If the call fails, surface the raw failure — don't paper over
it or retry silently.
Why --add-dir is still non-negotiable
The companion script always passes --add-dir "$(pwd)". Without it, agy
silently operates in its own internal scratch sandbox
(~/.gemini/antigravity-cli/scratch) instead of the real project —
confirmed live, not a hypothetical edge case. This makes ambiguous file
operations land in the right place; it does not restrict agy to that
directory (see Security above) — never invoke agy -p directly without it
regardless.
