Haikou Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a plain Haikou travel guide skill with no code, external calls, credentials, or persistence.

This skill is safe to install as a static travel reference. Treat practical details such as visa rules, emergency contacts, prices, routes, and weather as potentially stale and verify them before relying on them for travel decisions.

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

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 78% confidence
Finding: The file discusses language availability and effectively assumes Mandarin Chinese as the primary interaction context, while the skill does not mention any option to adapt responses to the user's preferred language or locale. Under the policy, locale or language constraints should be offered as a choice or clearly justified as region-specific; here the skill is travel-oriented and broadly user-facing.
Content: No source excerpt is available for this finding.
