AI Security Review
scanned 15d ago · by lpm-firewall-aiSource inspection found no automatic install hook or verified malicious behavior. The flagged agent configuration edits and persistence-related setup are reached through explicit product commands, and the reviewed endpoint is the package-aligned Agnoclast service.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the CLI setup, install, or uninstall command; Antigravity sync artifacts are generated through its editor adapter.
Impact
These actions configure or remove the intended Cortex integration; no unconsented attack impact was established.
Mechanism
The commands wire the Cortex service into user-level agent configuration, add managed skills or hooks, or remove those integrations. No install lifecycle hook activates these changes automatically.
AI rationale
Source inspection found no automatic install hook or verified malicious behavior. The flagged agent configuration edits and persistence-related setup are reached through explicit product commands, and the reviewed endpoint is the package-aligned Agnoclast service.

Decision evidence
public snapshotAI called this Clean at 87.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes a CLI and has no install lifecycle hook; its scripts are release, promote, and rollback commands.
- The CLI dispatches install and uninstall as explicit commands. Setup wires the Cortex MCP server into user configuration after receiving a token.
- Codex, Cursor, and skill changes target their respective user configuration directories; the cited editor paths describe their integration behavior.
- Uninstall is explicitly invoked and supports a dry run; Antigravity sync is generated only when the editor adapter is used.
- The reviewed dependencies are the MCP SDK and Zod; the inspected Zod entrypoint re-exports its library modules.
- Calendar event code identifies the Agnoclast service as its endpoint; no unrelated credential recipient or confirmed attack behavior was identified in the reviewed source.
