Security checks for vulnerabilities and agentic risk

Overview

This skill is a repo analysis and learning-plan writer that creates limited Markdown outputs under a disclosed `.learn/` directory.

Before installing, know that using this skill on a project will create or update Markdown files under that project's `.learn/` directory. Review those generated files before committing them, especially if the repository is shared or has automation that reacts to new files.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Description-Behavior Mismatch

Confidence

Finding

The skill is presented as analysis-oriented, but its instructions direct the agent to create and update files inside the target repository under .learn/. This creates an unexpected local side effect on user files, which can overwrite prior work, pollute repositories, or alter the working tree without an explicit, separate consent step.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
99% confidence
Finding

The skill explicitly instructs writing artifacts into the target project's .learn/ directory without any user-facing warning that local files will be created or modified. In the context of analyzing arbitrary local repos, this is dangerous because it normalizes silent workspace mutation and may interfere with version control, automation, or sensitive project contents.
