AI Security Review
scanned 25d ago · by lpm-firewall-aiThe source shows first-party agent integration that can extend agent behavior after explicit setup, supporting a warning. The manifest has no install lifecycle hook, and the inspected code does not establish malicious behavior.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user invokes the package’s setup command.
Impact
Agent behavior and later synchronization may be extended after setup and user activation. The inspected source does not show an unconsented install-time change or credential exfiltration.
Mechanism
Setup installs bundled and organization-published skills; the Antigravity adapter writes a sync script and launch-agent plist but leaves activation to a separate command.
AI rationale
The source shows first-party agent integration that can extend agent behavior after explicit setup, supporting a warning. The manifest has no install lifecycle hook, and the inspected code does not establish malicious behavior.
Evidence
lib/setup.mjslib/skills.mjslib/editors/antigravity.mjs
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json defines the CLI entry point and has no npm lifecycle hooks.
- The editor adapters detect existing Codex and Cursor configurations; Cursor is described as capture-only.
- Setup installs bundled and organization-published skills into agent CLI directories.
- The uninstall command targets Agnoclast-managed agent configuration and hook files.
- Antigravity setup writes a launch-agent plist and sync script but does not activate the watcher; activation requires a separate user command.
- The CLI routes setup through an explicit command, and that setup performs agent integration.
Evidence against
- The package has no preinstall, install, or postinstall hook.
- Antigravity setup reports that its sync depends on a local development checkout, and does not load the launch agent itself.
- The inspected source does not establish credential theft or an active attack.
