AI Security Review
scanned 16d ago · by lpm-firewall-aiThe source excerpts reviewed do not substantiate the scanner's malicious-behavior claims, and the manifest has no runtime self-dependency. Agent configuration behavior remains unresolved because the available excerpts do not show its full caller and consent flow, so a warning is appropriate rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
npm installation activates the postinstall repair script; agent setup and migration behavior requires explicit commands.
Impact
No confirmed malicious impact is established by these excerpts.
Mechanism
The inspected evidence shows a native repair hook and paths for agent-related setup, but does not establish unconsented broad configuration changes, credential exfiltration, or a backdoor.
AI rationale
The source excerpts reviewed do not substantiate the scanner's malicious-behavior claims, and the manifest has no runtime self-dependency. Agent configuration behavior remains unresolved because the available excerpts do not show its full caller and consent flow, so a warning is appropriate rather than a block.
Evidence
scripts/fix-better-sqlite3.cjsdist/commands/init.jsdist/commands/migrate.jsdist/commands/setup.js
Decision evidence
public snapshotAI called this Suspicious at 42.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package declares a postinstall hook that runs a native SQLite repair script.
- The inspected agent-related paths include setup, migration, and project initialization behavior; the supplied excerpts do not establish whether those operations require consent.
- The inspected Git sync excerpt initializes synchronization state but does not show persistence or remote-access backdoor behavior.
Evidence against
- The manifest has no runtime dependency on instar, so the lifecycle self-dependency chain is absent.
- The package's main and CLI entrypoints point to dist files; the inspected manifest does not show agent configuration writes during package installation.
- The required excerpts for several flagged paths show ordinary project setup, messaging, memory-path discovery, and test evidence handling.
