Rotating Single Target Cron

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed helper for creating rotating scheduled chat messages, with limited workspace state and no hidden executable behavior.

Before installing, confirm you are comfortable with the skill creating or editing a recurring chat job that posts to the selected chat and stores the last mentioned @ID in a workspace memory file. Review the roster, destination, schedule, timezone, and message style carefully, especially for public or group chats.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Low
Category

Confidence
92% confidence
Finding

This markdown example explicitly instructs the skill to "Write in Chinese" with no indication that the user can choose another language or that the locale restriction is required for a region-specific use case. That creates a natural-language locale policy concern under the rule for forced language selection.

Natural-Language Policy Violations

Confidence
92% confidence
Finding

The example requires a "Chinese wake-up message" but does not offer a language choice or explain why Chinese is mandatory. Forcing a specific language in a generic example can violate language/locale policy expectations.
