Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent weekly review helper with a small local draft-generating script and no evidence of hidden networking, credential access, persistence, or destructive behavior.

Installers should understand that the skill is meant to organize materials they provide into a weekly review. If using the helper script, run it on intentional inputs and specify an output path you are comfortable creating or overwriting. Consider narrowing trigger phrases in deployment environments that auto-activate skills from ordinary natural language.

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
Confidence
93% confidence
Finding
The trigger examples include broad natural-language phrases such as 'weekly review' and 'next week priorities' that are common in ordinary user requests. In agent/router systems, overly generic triggers can cause unintended activation of this skill on unrelated prompts, leading to misrouting, confusing behavior, or unnecessary access to user-provided notes and files.

Category
MCP Least Privilege
Confidence
89% confidence
Finding
The skill references a local script that can produce structured files and the static analysis indicates file-write capability, but the manifest does not declare any tool scope such as permissions or allowed-tools. This creates a mismatch between documented capability boundaries and actual behavior, which can lead to unintended file creation or modification without clear operator review.

Natural-Language Policy Violations

Medium
Confidence
85% confidence
Finding
The trigger phrase list mixes English and Chinese phrases, but the document does not explain whether the skill is intended for a Chinese-speaking context or offer any user opt-in for language/locale handling. Under the policy rule, forcing or assuming a specific language without explicit choice or justification is a natural-language policy concern.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The trigger phrase at line 8, "整理这周做了什么" ('organize what was done this week'), is broad natural language that could easily overlap with ordinary user requests outside the intended skill boundary. This can cause unintended invocation or routing confusion, especially in systems that select skills from loose semantic matches rather than explicit user choice.

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The smoke-test instructions and acceptance criteria are written entirely in Chinese, which imposes a specific language on users or reviewers without any opt-in or stated regional requirement. Under the policy, language constraints should either be optional for the user or clearly justified as region-specific.

Natural-Language Policy Violations

Low
Confidence
78% confidence
Finding
The file presents core instructions and user-facing content in a mixed Chinese/English format, but does not state whether users may choose their preferred language or locale. This can be a policy concern when a skill appears to impose a language style without user opt-in.
