AI Security Review
scanned 2d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook. The flagged persistence is opt-in, and the automatic agent configuration update installs only the package’s own confidential-session guard; the credential-related flow sends account proof to Agnoclast for the requested confidential-brain feature.
Static reason
No blocking static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
The confidential-session guard may be added during the configured SessionStart status hook. The periodic closeout scheduler runs only after its separate install command is invoked.
Impact
No malicious impact identified. The reviewed automatic behavior is limited to the package’s guard, and closeout persistence is opt-in.
Mechanism
The guard adds its own PreToolUse hook; the closeout command installs a launchd job. Confidential-session identity proof is sent to the Agnoclast API as part of opening that feature.
AI rationale
The manifest has no install lifecycle hook. The flagged persistence is opt-in, and the automatic agent configuration update installs only the package’s own confidential-session guard; the credential-related flow sends account proof to Agnoclast for the requested confidential-brain feature.

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 contains no install, preinstall, or postinstall hook.
- The closeout scheduler is a separate CLI command and is documented in source as off by default.
- The SessionStart self-heal adds only the package’s confidential-session guard hook when it is missing.
- The confidential-session proof is sent to the Agnoclast API when the server opens a confidential brain; the inspected flow does not send it to a foreign host.
Evidence against
- The status command can automatically write the guard hook to ~/.claude/settings.json during SessionStart.
- The optional closeout scheduler reads eligible Claude session transcripts and uses models on the user’s account. These actions are enabled by invoking its separate install command.
