Security checks for vulnerabilities and agentic risk

Overview

This weather skill is a small, disclosed set of curl examples for public weather services, with no hidden persistence or credential access.

Installing this skill means the agent may use curl to send requested location names or coordinates to wttr.in or Open-Meteo for weather results. Avoid using it for locations you consider sensitive, but the reviewed artifact does not show hidden collection, persistence, or destructive behavior.

A.I.G

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

External Transmission

Medium

Category: Data Exfiltration
Content: Free, no key, good for programmatic use: ```bash curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true" ``` Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
Confidence: 50% confidence
Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
