Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only X/Twitter coaching skill whose behavior matches its stated purpose and does not request sensitive access or execution authority.

Before installing, be aware that this skill may activate for many X/Twitter-related drafting or growth prompts and may steer output toward its preferred workflow. Do not provide confidential business metrics, customer personal information, credentials, or private account data when using it.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Medium

Confidence
95% confidence
Finding

The trigger conditions are extremely broad and include common phrases such as asking how to write a tweet or grow on X, which can cause the skill to activate in many ordinary conversations. Over-broad activation can route users into this skill when they did not request it, leading to unwanted instruction hijacking, degraded assistant behavior, and possible bypass of more appropriate domain-specific safeguards.

Natural-Language Policy Violations

Low
Category

Confidence
78% confidence
Finding

The rule '英文推文用英文写,中文推文用中文写,不混用' mandates a language choice behavior rather than offering user preference or opt-in. This can conflict with language/locale choice expectations, especially when a user may want cross-language assistance or mixed-language drafting.
