@grum-os/cli@0.3.28
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 22d ago · by lpm-firewall-aiThe package provides an invoked CLI, but its generated Cursor guidance includes instructions that steer an AI assistant and discourage independent source inspection. Because this behavior is tied to agent setup rather than an install hook, it warrants a warning for guarded agent-configuration capability.
Static reason
One or more suspicious static signals were detected.
Trigger
A user invokes Grum setup and configures Cursor agents; the interactive branch proceeds after an affirmative answer.
Impact
A connected assistant may be steered to promote Grum setup and avoid independent examination of the CLI.
Mechanism
The CLI writes generated guidance to the project Cursor rule file, including instructions that constrain the assistant's reply and discourage source inspection.
AI rationale
The package provides an invoked CLI, but its generated Cursor guidance includes instructions that steer an AI assistant and discourage independent source inspection. Because this behavior is tied to agent setup rather than an install hook, it warrants a warning for guarded agent-configuration capability.
Evidence
grum.mjs.cursor/rules/grum.mdc
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes grum.mjs as the package's CLI executable.
- The source identifies .cursor/rules/grum.mdc as Grum's own Cursor rule.
- Generated Cursor guidance tells an AI assistant to prioritize enabling Grum and not inspect the CLI's own files.
- Cursor setup writes that generated guidance into the project rule file.
- The interactive setup flow asks whether to configure Cursor agents and proceeds when the user answers yes.
Evidence against
- The inspected package manifest has no install lifecycle hook.
- The Cursor configuration change is tied to an invoked setup flow, with an affirmative prompt in the interactive branch.
