Late Night Companion

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed late-night emotional check-in prompt with no executable code, but users should be comfortable with its proactive one-message behavior.

Install this only if you want a skill that may proactively open a late-night emotional check-in when you are active or online during the configured quiet-hours window. Configure DND or opt-out preferences, and avoid enabling memory for sensitive emotional details unless you are comfortable with the host product retaining them.

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

Vague Triggers

Finding

The skill description explicitly says it activates automatically during late-night hours without a manual trigger. In an emotional-support context, broad proactive activation can cause unsolicited outreach based on weak signals such as mere online presence, creating privacy, consent, and boundary risks if users did not clearly opt in to nighttime check-ins.

Vague Triggers

Confidence
94% confidence
Finding

The auto-trigger logic is broad and underspecified: it fires when local time is in a wide window and either the user was active after 22:00 or the session is online, with only a narrow DND exclusion. Because 'session is online' is vague and negative constraints are minimal, the assistant could enter an emotional-support mode and proactively message users who did not expect or want intervention, especially in sensitive circumstances.
