Security audit

X Reply Unreplied

Security checks for vulnerabilities and agentic risk

Overview

This is a bounded X reply assistant that can like and post from the user's account, and that behavior is disclosed and aligned with its purpose.

Install this only if you are comfortable letting the agent use your logged-in X session to like posts and publish short replies on your behalf. Give a narrow scope and count limit when using it, and ask to review drafts first if you do not want automatic posting.

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

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The instruction 'Use this file whenever drafting a comment, reply, or post' is extremely broad and overlaps with common, everyday writing tasks. It does not define boundaries, exclusions, or specific contexts, so the skill could be invoked in many situations where it was not intended.

Vague Triggers

Medium
Category

Confidence
89% confidence
Finding

The instruction 'Use this file while handling notifications or mentions' is ambiguous because it does not clearly limit the context to X.com until later steps. A user or agent could reasonably interpret it as applying to any notification workflow, increasing the risk of unintended invocation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
76% confidence
Finding

The document instructs the agent to always use this file for drafting and defines a required emotional and behavioral baseline, without offering the user a choice in tone or style. This imposes a fixed communication style rather than allowing user preference or opt-in.
