Security audit

Access global ocean tides model. Functions include tide height at a given date/time/location, tide extrema, and grid weather data.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for calling a disclosed tide and weather API, with no hidden local access, persistence, or destructive behavior found.

Before installing, users should be comfortable sending queried coordinates, times, requested weather variables, and any optional hamandmore.net API token to the disclosed service endpoint. Avoid reusing unrelated secrets as this service token.

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
