DeFi Position Tracker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed DeFi portfolio-analysis guide that uses external portfolio APIs but does not include hidden execution, transaction signing, persistence, or destructive behavior.

Before installing, be aware that using the example commands can reveal wallet addresses, position IDs, portfolio details, and API keys to third-party DeFi data providers. Use read-only API keys where possible, review provider terms, and do not supply wallet private keys or seed phrases.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
77% confidence
Finding

The manifest focuses on tracking and analytics outputs for reporting, tax handoff, and dashboards, and explicitly says the skill is not for real-time price alerts on spot holdings without active DeFi positions. The 'Monitoring & Alerts' section adds operational alerting behavior, including health-factor thresholds and out-of-range detection, which extends beyond the described reporting-oriented scope even if related to DeFi positions.

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
72% confidence
Finding

The manifest states the skill 'outputs structured data for portfolio reporting, tax handoff ... and treasury dashboards.' In contrast, the workflow explicitly says to 'Generate markdown summary for treasury dashboard,' which adds a presentation/content-generation capability not clearly justified by the stated structured-data purpose.
