AI Security Review
scanned 25d ago · by lpm-firewall-aiThe package has no npm install hook, but its explicit cross-editor installer can write a package-owned Antigravity watcher configuration. Since activation requires a separate manual step and no malicious chain was established, this warrants a capability warning rather than a block.
Static reason
No blocking static signals were detected.
Trigger
A user invokes the package's install command while Antigravity is selected by detection or explicitly targeted.
Impact
If manually activated, the watcher can trigger the package's sync script when watched data changes. The script depends on a local development checkout, and no malicious effect was established.
Mechanism
The installer calls the Antigravity adapter, which writes a sync script and a launch-agent plist that watches Antigravity data. The plist disables RunAtLoad, so a separate manual activation is required.
AI rationale
The package has no npm install hook, but its explicit cross-editor installer can write a package-owned Antigravity watcher configuration. Since activation requires a separate manual step and no malicious chain was established, this warrants a capability warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 79.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest defines release, promote, and rollback scripts; it has no install lifecycle hook.
- The explicit install command defaults to detected editors and calls each selected adapter's wire function.
- The Antigravity adapter writes a launch agent and sync script under the user's home directory.
- The launch agent watches Antigravity data, but RunAtLoad is disabled; the adapter does not load it automatically.
- Setup requires a token and writes the package's MCP configuration; skills are installed into Claude and Codex skill directories.
- Uninstall changes are behind the uninstall command and support a dry-run mode.
Evidence against
- No inspected source establishes covert execution, credential theft, or an unrelated network recipient.
- The Antigravity watcher requires separate manual activation, and its sync script points to a local development checkout.
