AI Security Review
scanned 25d ago · by lpm-firewall-aiThe source shows a first-party Antigravity watcher setup that requires explicit setup and separate activation, so it warrants a warning under the agent extension policy. There is no package install hook, and the runtime self-invocation does not establish an automatic lifecycle self-dependency chain.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs setup and separately activates the generated launchd plist.
Impact
This is a guarded agent extension setup capability. Static inspection does not establish an attack or an npm-install-time trigger.
Mechanism
The adapter writes a shell script and plist; the script invokes this package through npx to run a sync from a local development checkout.
AI rationale
The source shows a first-party Antigravity watcher setup that requires explicit setup and separate activation, so it warrants a warning under the agent extension policy. There is no package install hook, and the runtime self-invocation does not establish an automatic lifecycle self-dependency chain.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest has no install lifecycle hooks; it exposes a CLI and lists only release, promote, and rollback scripts.
- The Antigravity adapter writes a launchd plist and sync script during setup, but does not load the plist; its warning says activation requires a separate launchctl command.
- When activated, the Antigravity watcher runs a one-shot sync through npx using this package’s stable release and a local development checkout.
Evidence against
- The package’s own setup command is needed to write the Antigravity artifacts, and the watcher is not activated by that write.
- The nested package invocation is runtime behavior; the manifest has no install hook to trigger a nested install during npm installation.
