MiroFish Predict

Security checks for vulnerabilities and agentic risk

Overview

The skill appears purpose-aligned for MiroFish simulations, but it installs mutable external code, starts an unpinned Docker-backed backend, uses an API key, and has broad triggers that could cause unexpected token spend.

Install only if you trust the MiroFish npm package and Docker image source. Configure the API key deliberately, watch token costs, start the backend only for intentional simulations, and prefer a pinned or reviewed CLI/container version before using it with sensitive files or paid credentials.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill description uses very broad activation triggers such as '推演', '預測', '模擬', and '如果…會怎樣', which are common in ordinary user requests and can cause the skill to activate unexpectedly. Because this skill launches a Docker-backed simulation workflow and may consume an API key and large amounts of LLM tokens, overbroad triggering increases the risk of unintended execution, cost, and surprise side effects.
