AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not malicious by the stated boundary because the control-surface writes require explicit user commands and no npm lifecycle hook performs them. It warrants a warning because it persists hooks and permissions in multiple AI-editor control surfaces and transmits session-derived data.
Static reason
No blocking static signals were detected.
Trigger
The user runs login, setup, install, or repair; configured editor hook events then invoke the package.
Impact
The package can persist within configured editor workflows, grant its MCP tools permissions, and send captured session information to its service.
Mechanism
User-invoked AI-editor extension setup with session capture and context injection.
AI rationale
This is not malicious by the stated boundary because the control-surface writes require explicit user commands and no npm lifecycle hook performs them. It warrants a warning because it persists hooks and permissions in multiple AI-editor control surfaces and transmits session-derived data.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit install command wires detected AI editors and records a local capability manifest.
- Claude setup adds a prompt-time hook and pre-authorizes the package's MCP tools.
- Codex setup writes an MCP server entry and a Stop hook.
- The capture hook posts session-derived data to the Cortex API.
- The Antigravity option writes a launchd plist and executable wrapper.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Configuration changes require an explicit setup, install, repair, or login command.
- The capture path redacts credential-shaped transcript content before upload.
- No source evidence shows credential theft, destructive behavior, hidden remote code loading, or an unconsented install-time mutation.
