AI Security Review
scanned 25d ago · by lpm-firewall-aiThe package has no npm install hook or confirmed malicious behavior. Its explicit install flow creates a guarded Antigravity launchd integration that requires manual activation, which warrants a warning under the agent integration policy.
Static reason
No blocking static signals were detected.
Trigger
A user invokes the CLI install flow with Antigravity selected or detected.
Impact
If a user loads the plist, changes to Antigravity state can trigger the sync script. No active attack was established from this guarded setup behavior.
Mechanism
The adapter writes a launchd plist that watches Antigravity state and points to a generated sync script; it leaves the plist unloaded.
AI rationale
The package has no npm install hook or confirmed malicious behavior. Its explicit install flow creates a guarded Antigravity launchd integration that requires manual activation, which warrants a warning under the agent integration policy.

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 no install lifecycle hook; agent wiring is reached through the CLI install flow.
- The Antigravity adapter writes a sync script and launchd plist, but does not load the agent.
- The plist watches Antigravity state and has RunAtLoad disabled; the CLI tells users to load it manually.
- Uninstall removes matching Cortex and Agnoclast launchd agents.
- Codex and Cursor integrations are scoped to their own configuration paths; Cursor is capture-only.
Evidence against
- The explicit install flow can create a launchd watcher that runs the generated sync script when Antigravity state changes.
