Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Chinese daily reflection journaling skill with no malicious code, though users should know it may save personal reflections to a local dated Markdown file.

Install only if you are comfortable using a Chinese-language reflection workflow and having entries saved locally under daily-reflection/YYYY-MM-DD.md. Avoid recording information you would not want stored in a workspace file, and review or delete entries manually when needed.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The trigger list includes broad, everyday phrases such as '回顾今天' and similar natural-language expressions that may appear in ordinary conversation, which increases the chance of unintended skill activation. In a journaling skill, accidental invocation can lead the assistant to solicit or record sensitive emotional or personal information when the user did not explicitly intend to start a reflection workflow.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The skill instructions and user-facing content are written entirely in Chinese and present Chinese trigger phrases and prompts, implying a fixed language experience. There is no opt-in language choice or explicit justification that the skill is intended only for Chinese-speaking users.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill instructs saving reflection content to a dated file, but gives no warning that highly personal reflections will be persisted to storage. Because the content likely includes emotions, behaviors, relationships, and sensitive life events, silent persistence creates a privacy risk if users do not understand retention, access scope, or whether saving is optional.

Natural-Language Policy Violations

Low
Category

Confidence
88% confidence
Finding

The entire prompt library and usage guidance are written only in Chinese, with no indication that users may choose another language or that the skill is intentionally limited to Chinese-speaking contexts. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation.
