AI Security Review
scanned 13d ago · by lpm-firewall-aiSource review found no malicious behavior: the package has no install lifecycle hook, and flagged configuration changes are tied to explicit CLI commands. Runtime authentication uses the user's Cortex token with the configured API base, defaulting to agnoclast.com; the Antigravity watcher is not activated automatically.
Static reason
No blocking static signals were detected.
Trigger
Configuration changes require explicit setup, install, or uninstall commands; Antigravity activation requires a separate user action.
Impact
No unintended effect was established; the observed behavior supports the package's Cortex integration.
Mechanism
The package wires its Cortex server and hooks into editor configuration and writes an Antigravity watcher without activating it.
AI rationale
Source review found no malicious behavior: the package has no install lifecycle hook, and flagged configuration changes are tied to explicit CLI commands. Runtime authentication uses the user's Cortex token with the configured API base, defaulting to agnoclast.com; the Antigravity watcher is not activated automatically.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines no install lifecycle hook; the inspected dependencies expose ordinary runtime entrypoints and no install hook.
- The Codex and Cursor configuration writes are reached through explicit setup or install CLI commands; setup requires a caller-supplied Cortex token.
- Runtime authentication uses the Cortex token with the configured API base, which defaults to agnoclast.com; no hidden unrelated recipient was found.
- Antigravity setup writes a script and launchd plist, but the source does not activate the watcher automatically.
- The remaining flagged files support user-invoked diagnostics, local extraction, project lookup, or uninstall behavior.
