Planner

Security checks across malware telemetry and agentic risk

Overview

This planner skill saves planning details locally and its behavior matches its stated purpose.

Install this if you want a local planner and are comfortable with your planning details being saved on this machine. Avoid storing secrets or highly sensitive personal information, and review or delete the planner JSON files if you no longer want the data retained.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill advertises local file storage and multiple scripts that read and write persistent plan data, but no explicit permissions are declared. That creates a transparency and policy-enforcement gap: users and the platform may not understand that the skill can persist and modify data on disk. In a planning skill, stored content can include sensitive personal schedules, travel plans, deadlines, and notes, so undeclared file access is security-relevant.

Vague Triggers

Medium
Confidence
84% confidence
Finding
The activation language is very broad, covering nearly any request involving planning, organizing, roadmaps, timelines, options, or next steps. Over-broad routing can cause the skill to activate in contexts the user did not intend, increasing exposure of sensitive conversational content to a tool with persistence capabilities. Because this skill stores data locally, accidental invocation is more dangerous than for a stateless formatter or calculator.

Content

name: planner
description: Local-first planning engine for trips, weeks, launches, projects, schedules, and structured decision-making. Use whenever the user wants to plan something, organize future steps, create a roadmap, map constraints, compare options, or turn a vague goal into a phased plan. Also use when the user says they need a plan, itinerary, schedule, rollout, timeline, or structured next steps. Local-only storage.
