@grum-os/cli@0.3.11
Keep a repository on the design contract reviewed in Grum: a local drift check, review requests, Cursor hooks and an MCP server.
AI Security Review
scanned 29d ago · by lpm-firewall-aiThe package has a CLI entry point without an install lifecycle hook. Agent configuration changes occur through explicit Grum setup or init behavior, so this is a warning-level agent capability rather than an install-time attack.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the Grum setup or init command.
Impact
The repository's supported agent integration is enabled; source inspection did not establish covert execution or data theft.
Mechanism
Initialization writes agent hook and MCP configuration and a repository rule pointer, subject to setup and project-link checks.
AI rationale
The package has a CLI entry point without an install lifecycle hook. Agent configuration changes occur through explicit Grum setup or init behavior, so this is a warning-level agent capability rather than an install-time attack.
Evidence
grum.mjs
Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes a user-run CLI and has no install lifecycle hook.
- The flagged agent integration is a Cursor rule path used by Grum.
- The init command accepts Cursor or Codex and requires a linked project unless explicitly run local-only.
- Cursor initialization writes hook and MCP configuration files in the repository.
Evidence against
- Setup requires an explicit command or interactive confirmation; no unconsented npm-time agent configuration mutation is shown.
- The inspected integration is first-party Grum setup, and no malicious payload execution or credential exfiltration was established.
