Nimble

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only Nimble scooter helper skill with no executable code, persistence, credential handling, or hidden behavior found.

Installers should understand that this skill is written for Chinese-language use and includes user-facing commands for scooter configuration and reset; review those device actions before using them, but the package itself is documentation-only and shows no unsafe execution behavior.

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

Confidence: 93% confidence
Finding: The manifest description, headings, and all example commands are written in Chinese, including required invocation phrases such as Nimble 连接 and Nimble 状态. This indicates a language-specific interaction model without any user opt-in, alternative locale, or explanation that the skill is intentionally limited to a Chinese-speaking region.
