Agent Self Improve

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local performance-analysis and optimization helper with some overbroad wording, but I found no hidden persistence, credential access, network behavior, or code-rewriting implementation.

Before installing, note that the docs and metadata overstate the capability and the profiler repeatedly executes whatever function you pass to it. Use it only on tasks where repeated execution is acceptable, and do not treat the package description's code-rewriting claim as an implemented or reviewed safety feature.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill documentation is written entirely in Chinese, including its description and usage sections, with no indication that language selection is optional or that the skill is region-specific. This creates a natural-language policy concern because it effectively imposes a specific language on users without opt-in.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The package description advertises sweeping capabilities such as performance analysis, strategy optimization, auto-tuning, and especially code self-rewriting without stating any trigger conditions, boundaries, or safety constraints. In an agent skill, this ambiguity is risky because it normalizes autonomous self-modification behavior that could be invoked too broadly or interpreted as permission to alter code or behavior without adequate approval or sandboxing.
