Agent Coordinator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, user-invoked Python coordinator with explicit local JSON input and optional export behavior, and no hidden network access, credential use, persistence, or destructive actions.

Install only if you are comfortable running a local Python helper. Avoid placing secrets or sensitive personal data in task descriptions or subtasks files, and review any exported JSON before sharing 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
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • 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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
90% confidence
Finding

The skill invokes a local Python coordinator and documents workflows that can read inputs and export results, but it declares no explicit tool scope or permissions. In an agent ecosystem, missing scope boundaries increases the chance that file read/write happens without clear user visibility or policy enforcement, especially when subtasks and exports may touch sensitive local data.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill promotes parallel data collection, multi-agent analysis, and exporting results, but it does not warn users about privacy risks, data propagation across workers, or the possibility of writing sensitive aggregated output to disk. In a coordination skill, parallelization can amplify exposure because the same sensitive prompt or dataset may be replicated to multiple agents and persisted in output artifacts.
