Security checks for vulnerabilities and agentic risk

Overview

This skill is a local financial-ledger checker that matches its stated purpose and does not show hidden network, persistence, credential, or destructive behavior.

Install only if you are comfortable pasting or providing local files containing financial ledger data to a local checker. The inspected package does not send data over the network, but its output and interface are primarily Chinese and it performs only the listed free checks, not full accounting or legal revenue-recognition review.

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
Vulnerability Patterns

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The file's comments, sample input, error messages, findings, notes, and disclaimer are all hard-coded in Chinese. This creates a locale/language policy issue because users are not given any option to receive outputs in another language or to opt into Chinese-only behavior.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The natural-language interface, usage text, and user-facing messages are entirely in Chinese, and the skill does not indicate any option to choose another language or opt into this locale. Under the policy rule, forcing a specific language without user choice is a natural-language policy violation unless the locale restriction is explicitly documented and justified.

Intent-Code Divergence

Finding

The inline documentation says non-JSON input is treated as plain-text material such as a pasted '合同全文' (full contract text). However, the manifest and the rest of this script consistently position the skill as checking a 预收账款与收入确认台账 ledger with headers, not arbitrary contract text. This is an active documentation contradiction about the intended input scope, even though the runtime behavior still just passes text to the local engine.

Natural-Language Policy Violations

Confidence
92% confidence
Finding

The only natural-language content in this manifest-style JSON file is a Chinese table header and data, which indicates the skill content is fixed to a specific language/locale. Under the policy, locale-specific behavior should either offer user choice or clearly document a justified regional constraint, neither of which is present in this file.
