AI Security Review
scanned 16d ago · by lpm-firewall-aiThe manifest has no automatic install lifecycle hook, and the reviewed agent configuration and persistence writes are tied to explicit setup behavior. Uninstall is also explicitly invoked; the inspected calendar and transcript helpers do not establish an attack.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Setup or uninstall is invoked through the CLI.
Impact
The inspected behavior configures or removes the package's integrations; no confirmed attack effect was established.
Mechanism
Setup writes assistant configuration and skill files; Antigravity setup writes a script and launch agent file but does not load the agent.
AI rationale
The manifest has no automatic install lifecycle hook, and the reviewed agent configuration and persistence writes are tied to explicit setup behavior. Uninstall is also explicitly invoked; the inspected calendar and transcript helpers do not establish an attack.
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 has no preinstall, install, or postinstall hook.
- The Codex, Cursor, setup, and skill files describe editor configuration and skill setup behavior.
- Antigravity setup writes its sync script and launch agent file; its source says it does not load the agent.
- Uninstall is an explicit CLI command, and supports a dry run.
- The working-files target locates a transcript by session ID.
- Calendar event code describes events in the Agnoclast calendar.
