AI Security Review
scanned 12d ago · by lpm-firewall-aiThe flagged behaviors are consistent with explicit product setup and removal, and the Antigravity watcher is not activated automatically. The SHA-1 use derives a local filename key; inspected network calls target the configured Cortex service or perform a reachability check.
Static reason
No blocking static signals were detected.
Trigger
A user runs setup, install, or uninstall; Antigravity’s watcher requires a separate manual load step.
Impact
No unintended execution, credential disclosure, destructive action, or unauthorized agent configuration change was established.
Mechanism
Setup writes product configuration and Antigravity artifacts. Uninstall removes matching package-managed entries and supports a dry run.
AI rationale
The flagged behaviors are consistent with explicit product setup and removal, and the Antigravity watcher is not activated automatically. The SHA-1 use derives a local filename key; inspected network calls target the configured Cortex service or perform a reachability check.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest has no install lifecycle hook; its listed scripts are release, promote, and rollback. Setup and uninstall run through explicit CLI commands.
- Codex and Cursor adapters write the package’s named MCP configuration and preserve other entries; the related setup paths are part of the explicit setup flow.
- Antigravity setup writes a watcher and script, but the plist sets RunAtLoad to false and its warning says the user must load it to activate the watcher.
- The inspected API client uses the Agnoclast service by default; a separate fixed GET checks internet reachability. The SHA-1 match creates a local lookup key for a file, not a security decision.
- The flagged extraction, graph, obligation review, and working-file code performs product functions on local session or repository data; no attack behavior was identified in the inspected excerpts.
- Uninstall runs only through its explicit command and supports a dry run; its source targets the package’s configuration and named artifacts.
- The SDK manifest excerpt lists check and test commands.
- The Zod manifest excerpt lists build and postbuild scripts.
