AI Security Review
scanned 25d ago · by lpm-firewall-aiThe package has no install lifecycle hook, and the reviewed configuration changes are part of explicit setup or uninstall flows. Its guarded agent integration capability warrants a warning, but the inspected source does not establish malicious behavior.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the setup command; the Antigravity launch agent is not loaded by the adapter itself.
Impact
Configured agents may run package hooks, and the Antigravity artifact can support later background synchronization if activated.
Mechanism
Setup wires agent configuration and hooks. The Antigravity adapter writes a script and launch agent plist for later use.
AI rationale
The package has no install lifecycle hook, and the reviewed configuration changes are part of explicit setup or uninstall flows. Its guarded agent integration capability warrants a warning, but the inspected source does not establish malicious behavior.
Evidence
lib/setup.mjslib/editors/antigravity.mjs~/.claude.json~/.claude/settings.json~/.codex/config.toml~/.codex/hooks.json~/Library/LaunchAgents/com.cortex.antigravity-sync.plist~/.cortex/antigravity-sync.sh
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 a CLI entrypoint and no install lifecycle hooks.
- The Codex and Cursor adapters are editor configuration integrations; the supplied locations show their detection and capabilities.
- Setup wires the package into agent configuration, including a Codex capture hook.
- The Antigravity adapter writes a shell script and launch agent files but does not load the launch agent itself.
- Uninstall is an explicit command and supports a dry-run mode.
Evidence against
- No source evidence inspected establishes credential theft, malicious exfiltration, destructive behavior, or an unconsented install-hook mutation.
