AI Security Review

scanned 5d ago · by lpm-firewall-ai

The agent configuration is installed only through an explicit migration command, so the source does not establish unconsented lifecycle abuse. However, the generated always-applied Cursor rule contains destructive recovery guidance, leaving a concrete project-level risk that warrants a warning.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the migration CLI on a project.

Impact

An agent following the rule may delete project files, and existing project agent guidance may be removed.

Mechanism

The migration scaffolds a persistent Cursor rule with destructive recovery guidance; it also removes src/AGENTS.md during cleanup.

AI rationale

Evidence

package.jsonscripts/migrate.tsscripts/migrate/phase-scaffold.tsscripts/migrate/phase-cleanup.tsscripts/migrate/templates/cursor-rules.ts.cursor/rules/migration-tooling-policy.mdcsrc/AGENTS.md

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json exposes CLI commands and has no install lifecycle script.
Running the migration command proceeds through scaffold and cleanup phases.
The scaffold writes an always-applied Cursor rule into the migrated project.
That rule advises an agent to delete the working tree and rerun if migration fails.
Cleanup also removes src/AGENTS.md during migration.

Evidence against

The agent configuration changes occur as part of the explicitly invoked migration command, not during package installation.
The Cursor rule is first-party migration guidance; the inspected source does not show it executing a deletion itself.
