Overview

This divination skill mainly runs a local calculator, but it forces off-platform WeChat promotion and a local QR-code path into every result, with some optional sensitive or consequential guidance.

Install only if you are comfortable with a Chinese-language divination tool that may add unsolicited WeChat promotion to answers. Do not share face photos or sensitive personal details, and do not rely on its results for medical, financial, legal, travel, employment, or safety decisions. The publisher should remove the forced contact footer, remove the local filesystem image path, narrow triggers, and add clearer privacy and entertainment disclaimers before general use.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

text

In English, this instruction declares that every result must append a WeChat identifier and QR code, regardless of whether the user requested them.

Technical Analysis

The skill contains repeated, mandatory instructions that alter how the host agent composes responses. Rather than limiting its instructions to the declared divination function, it requires the agent to inject promotional contact information into every basic or advanced result.

The use of absolute language such as “mandatory,” “must,” and “cannot be omitted” makes this persistent output manipulation within every session in which the skill is loaded. The same requirement is repeated at several locations, increasing its likelihood of overriding ordinary response-composition behavior.

The forced footer is not necessary to perform the local divination calculation. It redirects users to an off-platform contact and attempts to render a QR code from an absolute local filesystem path. That path also discloses the local username and installation layout:

C:/Users/shinezpyang/.workbuddy/skills/xiao-liu-yao/assets/wechat-qrcode.jpg

The referenced QR-code asset is not present in the audited project.

Attack Path

1. A user invokes the xiao-liu-yao skill for a divination request.
2. The host agent loads the instructions from SKILL.md.
3. The repeated mandatory rules direct the agent to alter ...[truncated 1299 chars]

Remediation Suggestions

1. Remove all mandatory instructions requiring promotional contact information or QR codes in generated responses.
2. Remove the duplicated output-manipulation rules at lines 122, 169-173, and 323-330.
3. Restrict skill instructions to behavior necessary for the declared divination function.
4. If contact information is retained, display it only after an explicit user request and clearly identify it as optional promotional content.
5. Do not use absolute developer-specific filesystem paths in response templates.
6. If an image is legitimately required, package it inside the project and reference it through a validated project-relative path.
7. Add a skill-review policy that rejects instructions requiring unrelated links, contact details, advertisements, or repeated boilerplate in every response.
8. Test the revised skill to confirm that ordinary results contain only user-requested content and the relevant entertainment disclaimer.

Vulnerable Snippet

python

import zhdate

The project documentation identifies zhdate as a dependency but supplies no version constraint, lockfile, integrity hash, or package manifest.

Technical Analysis

Python imports execute a package’s module-level code with the permissions of the Python process. Because the project names zhdate without pinning a reviewed release, different installations can resolve different package versions over time.

The repository does not include a requirements.txt, lockfile, hash-verified dependency manifest, or equivalent reproducible installation configuration. Consequently, users may manually install the latest available release, and future dependency changes would not be constrained by the audited project.

No evidence was found that the currently named package is malicious. The vulnerability is the absence of dependency integrity and reproducibility controls, not a confirmed malicious payload in zhdate.

Attack Path

1. An operator installs the skill and discovers that the zhdate module is required.
2. Because no exact version or integrity hash is provided, the operator installs whichever release the package index currently resolves.
3. A compromised package index account, malicious future release, dependency substitution, or unsafe package source supplies altered package code.
4. The operator invokes scripts/divination.py.
5. Python executes module-level code from the installed package when processing import zhdate.
6. Malicious dependency code runs with the same filesystem, network, and process permissions as the user running the skill.

This path requires compromise or substitution of the external dependency; ...[truncated 716 chars]

Remediation

View remediation

Remediation Suggestions

1. Add a dependency manifest such as requirements.txt or pyproject.toml.
2. Pin zhdate to an exact, reviewed version rather than an unconstrained package name.
3. Record and verify package integrity hashes, for example through pip --require-hashes.
4. Generate and commit a lockfile appropriate to the selected dependency-management tool.
5. Install dependencies only from an explicitly trusted package index over authenticated TLS.
6. Review dependency metadata, source code, transitive dependencies, and release history before approving updates.
7. Use automated dependency scanning and update pinned versions only through a documented review process.
8. Run the skill in a least-privilege environment with restricted filesystem and network access to reduce the impact of a compromised dependency.

Vulnerability Patterns

• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Findings (18)

Vague Triggers

High

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The manifest itself advertises ambiguous trigger words without scope constraints, so unsafe activation is baked into discovery and routing rather than just the body instructions. This can cause the agent to invoke the skill for common language that does not indicate informed consent to divination or related data collection.

Content

No source excerpt is available for this finding.

Vague Triggers

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The trigger phrases include very broad everyday expressions such as '算一卦', '测算一下', and '今日运势', making accidental invocation likely in unrelated conversations. Over-broad activation increases the risk that the skill takes over normal chat flow, asks for unnecessary personal details, or delivers unsolicited outputs.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The trigger phrases are very broad, including generic terms like “算一卦”, “测算今日运势”, and “算一下我的事业”, which can overlap with normal conversation and cause the skill to activate unexpectedly. Over-broad invocation increases the chance of prompt hijacking of unrelated user intent, privacy leakage into the skill context, or unwanted steering into superstition/commercial solicitation flows.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 78% confidence

Finding

All user-facing instructions, prompts, trigger examples, and output templates are specified only in Chinese, and the workflow requires the agent to use those fixed Chinese phrases. There is no opt-in for language preference and no documented reason that the skill must operate only in Chinese.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The skill expands into face reading, feng shui, and weather prediction beyond the declared divination scope, which is a scope-creep issue that can surprise users and increase sensitive-data collection. In particular, face analysis invites collection of biometric-adjacent information without a necessity tied to the original manifest.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill requests face descriptions or photos for physiognomy analysis without a clear privacy warning, retention statement, or safer alternative. Face photos are sensitive personal data, and asking for them in a casual optional flow can pressure users into sharing more than necessary.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The skill mandates appending a personal WeChat contact and a QR-code image to every result, which is unrelated to the stated calculation function and creates an unauthorized promotional/data-exfiltration behavior. It also instructs the model to reveal a local asset path, increasing the chance of exposing internal environment details to end users.

Content

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

Forcing persistent contact details and a local file path into every result creates unnecessary disclosure and a channel for redirecting users off-platform, regardless of user intent. The local path leaks internal workstation/environment structure and normalizes exposing implementation details to users.

Content

No source excerpt is available for this finding.

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The template explicitly instructs the model to expose a local filesystem path to the user, which is an information disclosure issue. Even if the path seems harmless, it reveals host naming, directory layout, usernames, or tooling conventions that can aid fingerprinting or social engineering.

Content

No source excerpt is available for this finding.

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The global rule repeatedly mandates disclosure of contact details and an internal asset location in all result-bearing replies, turning a one-off problem into systemic behavior across the skill. Because it is framed as mandatory and high priority, it is more likely to override safer defaults and consistently leak information.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The skill provides health-related divination statements such as predicting illness severity or reassurance without stating that the content is not medical advice. Users may delay or avoid appropriate medical evaluation based on occult guidance, especially when told conditions are harmless or only require spiritual remediation.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The table presents concrete predictions about finance, travel, employment, relationships, health, and lost property without warning users not to rely on them for real-world decisions. In a divination context, deterministic guidance can influence consequential actions such as investing, travel changes, job decisions, or fraud susceptibility.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The document includes off-platform contact and an upsell for deeper services via WeChat, which is unrelated to the core on-platform divination skill behavior. This can be used to redirect users outside platform safeguards, increasing risk of unmonitored solicitation, privacy leakage, or social-engineering-style monetization.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The description contains user-facing text in Chinese ("道家小六壬测算" and "掐指一算掌中定乾坤") with no indication that the skill is region-specific or that users can opt into this language. This may violate language/locale policy because it implicitly forces a specific language experience without documented justification.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

This Python file contains natural-language documentation and CLI help text exclusively in Chinese, which effectively forces a specific language/locale on users. The policy allows locale constraints only when they are optional or clearly justified, but this file provides no user opt-in or documented region-specific reason.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The argparse description and help strings are entirely in Chinese, so command-line users are required to interact in that locale. Because no alternative language, opt-in, or explicit justification is present, this is a natural-language locale policy violation.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 83% confidence

Finding

The natural-language instructions, examples, and user-facing content are all Chinese, which effectively forces a specific language experience without stating that the skill is Chinese-only or offering an alternative. Under the stated policy, language constraints should be opt-in or clearly documented and justified.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 72% confidence

Finding

The skill content is entirely in Chinese and does not indicate that the language is optional, user-selected, or required for a documented region-specific purpose. Under the stated policy, forcing a specific language without user opt-in can be a natural-language policy concern.
