TypeScript CLI for Todoist

AI Security Review

scanned 25d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically rewrites existing Todoist skills in several foreign AI-agent configuration directories. It also performs a legacy-token migration that contacts Todoist.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install runs postinstall.

Impact

Changes agent behavior without an explicit setup command and can make an authenticated API request during installation.

Mechanism

Automatic agent-skill overwrite and legacy authentication migration.

Policy narrative

A normal npm installation launches postinstall. That code detects existing Todoist skill files in multiple AI-agent configuration surfaces and overwrites them with package-provided instructions, without a user setup command. The same automatic path migrates a legacy token and sends it to Todoist's API. The local bundled content and conditional update limit scope, but do not provide consent for installation-time changes to foreign agent control surfaces.

AI rationale

This is an unconsented postinstall mutation of multiple foreign AI-agent control surfaces, which meets the blocking policy. The additional install-time authenticated request increases the impact.

Semantic Analysis Limited

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.
