Focus Deep Work

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed focus-session helper with local tracking and optional device-setting changes, with no executable code or hidden data flow found.

Before installing, verify that the agent asks before muting notifications, blocking sites, closing or minimizing apps, or changing brightness. The reviewed artifact says focus data stays local and contains no executable code.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Shadow Command Trigger

Medium
Category
Trigger Abuse
Confidence
89% confidence
Finding

The trigger phrase "start focus" begins with the generic built-in verb "start," creating a shadowing/conflict risk with platform-native commands or other skills. This can cause the assistant to route a user request unpredictably, resulting in accidental activation of focus-mode actions or failure of the intended built-in command.

Vague Triggers

Category

Confidence
95% confidence
Finding

The listed triggers are broad, natural-language phrases such as "focus mode" and "start focus" that are likely to occur in ordinary conversation or overlap with other assistant actions. In a skill that can silence notifications, block apps, and change device environment, unintended activation could disrupt the user’s workflow or trigger system changes without clear intent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The usage section adds more ambiguous phrases like "Minimize distractions" and "Lock me in," which are colloquial and could plausibly be spoken in unrelated contexts. Because these commands can lead to environmental or system-level changes, accidental matching increases the chance of unintended behavior and user confusion.
