AI Security Review
scanned 12d ago · by lpm-firewall-aiThe manifest has no npm lifecycle hook, and the flagged configuration and persistence behavior is reachable through explicit CLI setup or install commands. The Antigravity plist is not activated automatically, while the SHA-1 use only derives a local cache key; no concrete attack behavior was identified.
Static reason
No blocking static signals were detected.
Trigger
A user explicitly invokes the setup or install CLI command.
Impact
No unconsented install-time mutation, active persistence, or other attack behavior was confirmed.
Mechanism
The package merges its editor configuration and can write an Antigravity watcher script and plist; the plist does not run at load and the adapter does not activate it.
AI rationale
The manifest has no npm lifecycle hook, and the flagged configuration and persistence behavior is reachable through explicit CLI setup or install commands. The Antigravity plist is not activated automatically, while the SHA-1 use only derives a local cache key; no concrete attack behavior was identified.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes a CLI and lists release, promote, and rollback scripts; it declares no npm install lifecycle hook.
- setup, install, and uninstall run through explicit CLI command branches; install also requires a supplied or already wired token.
- Codex and Cursor configuration changes use editor-specific merges, and setup writes the Codex configuration through its setup flow.
- The Antigravity adapter writes a watcher script and plist, but the plist sets RunAtLoad to false and the adapter does not load it.
- The SHA-1 use in capture derives a local cache filename from a working directory; inspected dependencies are the MCP SDK and Zod, whose inspected entrypoints expose library code.
- Inspected diagnosis, extraction, graph sync, obligation review, working-file tracking, and uninstall code supports the package’s runtime features; no concrete attack behavior was identified.
