Security checks for vulnerabilities and agentic risk
Overview
This marketing skill is mostly coherent, but it needs Review because it can read user-specified data files and makes privacy/retention promises the package does not appear able to enforce.
Install only in an environment where Read is restricted to the skill bundle and host-verified current-session uploads. Do not provide PII, credentials, arbitrary local paths, or sensitive raw business exports unless the host privacy and retention terms independently cover them. Treat deletion, no-third-party-sharing, and Vault retention statements as documentation claims, not enforceable guarantees from this package. Regulated outputs such as medical aesthetics, finance, education, food, and crisis PR should receive human legal/compliance review before use.
Vulnerability Patterns
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
- 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

声明描述的是一个面向营销策划与代理服务的技能；而代码是独立的 CLI 测试脚本，用于执行 eval 用例和质量门禁检查。两者在核心目的、能力和触发方式上都明显不一致。虽然代码文件名和注释包含 MktClaw，但这只是评测基础设施，不是实现所宣称营销代理功能的支持性细节，因此应判定为明显不匹配。

Vague Triggers
High
- Category
- Not specified by scanner
- Confidence
- 96% confidence
- Finding
The description instructs the assistant to trigger on very broad marketing-related topics 'even if the user did not explicitly say agency,' which can cause unsolicited activation and scope hijacking in benign conversations. In a multi-skill environment, this increases the chance the skill overrides user intent, captures unrelated tasks, or injects specialized behavior when not clearly requested.

Intent-Code Divergence
High

- Confidence
- 96% confidence
- Finding
The document is for medical-aesthetic marketing, repeatedly acknowledges that the sector is subject to strict medical-advertising regulation, yet includes the guidance '明确"医美非医疗"' as a way to avoid a risk. That statement is materially misleading in context and could encourage users to misclassify regulated medical services, weakening compliance controls and producing unlawful or deceptive ad content.

Autonomous Decision Making
Medium
- Category
- Excessive Agency
- Confidence
- 75% confidence
- Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Missing User Warnings
Medium
- Category
- Not specified by scanner
- Confidence
- 92% confidence
- Finding
The README advertises one-command self-evolution flows that can learn from production logs, update the knowledge base, and bump versions, but it does not prominently warn that these operations may modify repository contents. In an agent-skill context, this is risky because users or orchestrators may treat README commands as safe operational guidance and trigger autonomous code/content changes from potentially untrusted runtime data.

Vague Triggers
Medium
- Category
- Not specified by scanner
- Confidence
- 90% confidence
- Finding
The trigger table maps broad keywords such as brand positioning, growth strategy, KOL, livestreaming, and crisis response directly to role activation without defining exclusions or ambiguity handling. This makes the skill more dangerous in context because it is designed to activate across many common business topics, increasing accidental invocation and potential interference with safer or more appropriate skills.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 95% confidence
- Finding
The skill instructions are written as direct operational guidance in Chinese and define the agent persona and interaction behavior entirely in Chinese. There is no statement offering multilingual support or allowing the user to choose language, which creates a language-policy concern under the locale/language rule.
- Content
Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 93% confidence
- Finding
The file description and instructions are written to operate in Chinese and present the skill as a Chinese-language router, but there is no indication that the user can choose another language or opt in to this locale constraint. Under the policy, forcing a specific language without user choice is a natural-language policy violation unless the limitation is clearly justified.
- Content
Missing User Warnings
Medium
- Category
- Not specified by scanner
- Confidence
- 92% confidence
- Finding
The router explicitly enables automatic progression into downstream execution in one-click fast mode without user confirmation. In this skill, that behavior is more dangerous because the system can route into sensitive marketing functions such as crisis PR, compliance-sensitive industries, and strategy generation, increasing the chance of unintended or unsafe outputs being produced without a final user checkpoint.
- Content
Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The manifest description and the operational instructions are written entirely in Chinese, with no indication that language is configurable or limited to a China-specific/regional compliance use case. This creates a natural-language policy concern because the skill appears to impose a specific language/locale without user opt-in.
- Content
Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 96% confidence
- Finding
The manifest description and the main instructional content are written entirely in Chinese, and the skill frames the agent role in Chinese without indicating that other languages are supported on request. This creates a locale/language policy concern because it implicitly fixes the interaction language rather than offering a user choice or documenting a justified region-specific constraint.

Medium
- Category
- Not specified by scanner
- Confidence
- 92% confidence
- Finding
The description is written entirely in Chinese and presents the workflow as a Chinese-language brand design consultant flow, with no indication that users can choose another language. Under the policy rules, forcing a specific language or locale without opt-in is a natural-language policy violation unless clearly justified as region-specific.
- Content
Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 95% confidence
- Finding
The skill is written to operate directly in Chinese and does not offer any user-language choice or fallback, which can cause users to misunderstand instructions, outputs, or constraints if they are interacting in another language. In an agent setting, forced-language behavior can degrade transparency and informed consent, and may lead to incorrect business or production decisions because the user cannot reliably validate what the agent is doing.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 93% confidence
- Finding
The workflow description is written entirely in Chinese and presents the skill behavior as Chinese-language content production without offering any language or locale choice. This can violate language/locale policy when a skill implicitly forces a specific language without user opt-in or justification.
- Content
Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 92% confidence
- Finding
The skill is written to operate in Chinese and strongly frames its behavior in Chinese without offering any user-language negotiation or opt-in. This can cause unsafe misunderstandings of user requests, consent, compliance requirements, or generated deliverables when the user expects another language, especially in a marketing workflow where legal and brand wording matters.

Medium
- Category
- Not specified by scanner
- Confidence
- 93% confidence
- Finding
The natural-language description is entirely in Chinese and presents the workflow as a Chinese-language creative director delivery flow, with no indication that language is selectable or optional. Under the policy, forcing a specific language or locale without user opt-in is a reportable issue unless the regional constraint is explicitly justified.

Medium
- Category
- Not specified by scanner
- Confidence
- 96% confidence
- Finding
The title, description, and all operating instructions are written as mandatory Chinese-language guidance, with no indication that the user may choose another language or that the skill is restricted to a Chinese-language/regional compliance context. This creates a natural-language locale policy concern because it implicitly fixes the interaction language without opt-in.
