Security checks for vulnerabilities and agentic risk
Overview
The skill is mostly a Chinese writing and story reference pack, but its security chapter includes instructions to persistently change an agent's global behavior files and claim unoverridable priority.
Review this carefully before installing. The writing references themselves are ordinary, but do not copy the security templates into global AGENTS.md, SOUL.md, or IDENTITY.md unless you intentionally want this skill to affect future agent sessions. Prefer keeping any rules skill-local, removable, and subordinate to platform and user instructions.
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

Hidden Instructions
High
- Category
- Prompt Injection
- Confidence
- 92% confidence
- Finding
The file begins with a hidden Unicode BOM/non-printing character, which can conceal content differences, interfere with downstream parsers, or evade simplistic security/pattern matching that assumes visible text starts at the first byte. In a skill ecosystem that relies on text inspection and instruction parsing, hidden characters increase the risk of parser confusion and filter bypass, even if the surrounding content is ostensibly defensive.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 96% confidence
- Finding
The entire skill is written as a Chinese-only template set and all output formats, labels, and examples are specified in Chinese, with no indication that users may choose another language. Under the policy, language constraints should be optional or explicitly justified; this file does neither.

- Confidence
- 93% confidence
- Finding
The entire skill reference is written exclusively in Chinese and does not indicate that the user may choose another language or that the content is intended only for a Chinese-language context. Under the language/locale policy, forcing a single language without opt-in is a natural-language policy concern.

- Finding
The entire skill file is written as mandatory Chinese operational guidance and includes example user-facing responses only in Chinese, with no indication that users may choose another language. Under the policy rules, a skill that implicitly enforces a specific language without opt-in or justification is a natural-language policy concern.

- Finding
The entire skill document is written as a Chinese-only operational specification, and examples of system responses and prompts are all fixed in Chinese. There is no indication that users may choose another language or that the locale restriction is required for a region-specific purpose, which can violate language/locale policy requirements.

- Confidence
- 83% confidence
- Finding
The document begins entirely in Chinese and provides all operational examples, warnings, and response templates only in that language. Under the policy, a skill should not impose a specific language or locale unless it offers user choice or clearly documents a justified region-specific constraint.

Intent-Code Divergence
Medium
- Category
- Not specified by scanner
- Confidence
- 98% confidence
- Finding
The worked threat-score examples do not match the scoring function shown in code, which can cause defenders to tune thresholds or response actions based on incorrect assumptions. In security controls, documentation/code mismatch is dangerous because it leads to overconfidence, misconfiguration, and inconsistent enforcement under real attack conditions.

Intent-Code Divergence
Medium
- Category
- Not specified by scanner
- Confidence
- 97% confidence
- Finding
The document’s false-positive mitigation depends on quote recognition, but no such detection logic is implemented in the provided algorithms. This creates a gap between documented behavior and actual defenses, making operators believe benign quoted text will be safely distinguished when in practice it may be blocked incorrectly or handled inconsistently.

- Finding
The document title and all operative instructions are presented only in Chinese, framing the skill's required behavior and guidance in a single language. Under the policy, forcing a specific language without an explicit user choice or documented regional justification is a natural-language policy violation.

Lines L003-L027 and the overall chapter framing present this file as a passive space for users to create and maintain their own analysis reports. However, L101-L110 switches intent and describes a different module ('小说档案馆') with crawling/mining behavior, which contradicts the stated purpose of this chapter's documentation rather than merely extending it.

- Finding
The guide specifies a fixed locale/style requirement, "标点规范：繁体中文引号「」", as an instruction for output. This imposes a specific language/locale convention without indicating user opt-in or that the skill is region-specific, which matches the language/locale policy concern.
