Text Stats

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward text statistics tool that reads user-provided text files or stdin and does not show hidden, persistent, networked, or destructive behavior.

Install only if you are comfortable with the agent using this skill on text you explicitly provide or files you name. Avoid pointing it at sensitive files unless you intend their contents to be read for local analysis.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
86% confidence
Finding

The skill advertises and demonstrates reading arbitrary files or stdin, but the manifest declares no explicit tool scope such as permissions or allowed-tools. That mismatch can cause the agent to invoke file-reading behavior without a clearly constrained authorization boundary, increasing the chance of unintended access to sensitive local files when the skill is selected.

Vague Triggers

Category
Not specified by scanner
Confidence
93% confidence
Finding

The description uses broad routing language such as 'any text content,' which can cause the skill to be selected for a very wide range of prompts. In context, that overmatching is risky because the skill reads files/stdin, so ambiguous invocation could expose user content to a tool unnecessarily or trigger analysis of files beyond the user's intended target.
