ev-charge-planner

Security checks for vulnerabilities and agentic risk

Overview

This skill appears to be an offline EV charging calculator with only a minor command-line documentation mismatch.

Reasonable to install if you want offline EV charging math. Treat the electrical-panel output as planning guidance only, not a substitute for an electrician or local code review, and use --ev-mi-per-kwh rather than the ignored --kwh100mi option.

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

Finding

The inline help explicitly documents --kwh100mi as 'ignored; use --ev-mi-per-kwh', which indicates a deliberate mismatch between the exposed interface and actual intended behavior. This is an intent/documentation divergence because the code advertises a parameter while simultaneously declaring it unused, and no code path consumes it.
