AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo npm lifecycle hook executes this behavior automatically, but explicit commands can configure agent hooks and send captured session data. Treat this as a dangerous, user-invoked agent extension capability requiring a warning rather than a block.
Static reason
No blocking static signals were detected.
Trigger
A user runs setup or install; later, a configured AI-agent Stop hook runs capture.
Impact
The package can persist package-owned AI-agent integration and transmit captured session content or derived summaries using the configured token.
Mechanism
User-invoked AI-agent configuration and session capture.
AI rationale
No npm lifecycle hook executes this behavior automatically, but explicit commands can configure agent hooks and send captured session data. Treat this as a dangerous, user-invoked agent extension capability requiring a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The package exposes a command-line program.
- The explicit install command wires detected AI editors and writes a capability manifest.
- The uninstall command modifies Claude, Codex, and Cursor configuration and hooks.
- The Antigravity adapter writes a shell script and a launchd plist that can enable a watcher.
- A configured capture hook posts session-derived data to the Agnoclast ingest API.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Configuration changes are reached through named CLI commands, not package installation or import.
- The Antigravity adapter deliberately does not load its launchd plist.
- The inspected network client targets the package-aligned Agnoclast service and uses an explicitly resolved token.
