Security audit

Goal Decomposer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward goal-planning helper with no evidence of hidden execution, persistence, credential access, or data exfiltration.

Install only if a Chinese-first, template-based planning helper is acceptable. Review generated subtasks before acting on spawn_hint suggestions, especially when they involve web research or other agents.

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
89% confidence
Finding

This markdown file is entirely written in Chinese and does not indicate that language selection is optional or that the skill is intended only for a Chinese-speaking or region-specific audience. Under the policy, forcing a specific language without user opt-in or documented justification is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The primary description is written in Chinese and presents the skill behavior in that language without any note about letting users choose their preferred language. Under the policy criteria, forcing a specific language or locale without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill description is written to operate in Chinese without documenting locale constraints or user preference handling, which can force language behavior that does not match the user's request. This is primarily a safety and usability issue: users may misinterpret generated tasks or fail to review them accurately, increasing the chance of mistaken execution in multilingual environments.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger description is broad enough to match many ordinary planning requests, which can cause the skill to activate when the user did not explicitly ask for goal decomposition. In an agent system with spawning and routing capabilities, unintended invocation can alter task flow, introduce unnecessary automation, or cause downstream actions to be proposed or initiated from an overly generic prompt.

Confidence
92% confidence
Finding

This JSON example specifies the goal, context, and constraints entirely in Chinese, indicating the skill content is tailored to a single language/locale without any visible opt-in or alternative. Under the policy, forcing a specific language without user choice can be a natural-language policy violation unless the locale limitation is clearly justified.

Finding

This JSON contains user-facing goals, constraints, task titles, descriptions, and spawn hints exclusively in Chinese. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale restriction is documented and justified, which is not present here.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest describes decomposing high-level natural-language goals into executable multi-level task lists, especially for vague or complex goals. In code, decomposition is driven only by coarse keyword classification and hardcoded templates, and the context parameter is unused, so actual behavior is much narrower than the claimed adaptive goal decomposition.

Natural-Language Policy Violations

Category

Confidence
90% confidence
Finding

This JSON skill content is entirely written in Chinese, including the input goal, context, task titles, descriptions, and KPI strings. Because there is no accompanying indication that the skill is region-specific or that the user can choose their preferred language, it may violate a language/locale policy requiring user choice or explicit justification.

Confidence

Finding

This markdown file presents all instructions and examples exclusively in Chinese, which can constitute a language/locale policy issue when no user opt-in or justification is provided. The policy specifically flags skills that force a specific language without offering a choice.

Finding

SQP-3 applies to all file types and covers language or locale policy violations. This skill file forces a specific language for the user-facing content and examples, but does not provide any opt-in, alternative language, or justification for restricting the skill to Chinese.

Confidence
87% confidence
Finding

The file uses Chinese-only natural-language descriptions and keyword logic, including the title and docstrings, and classification depends on Chinese trigger words. Under the policy, forcing a specific language without user opt-in can be a locale/language policy violation.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The docstring 拆解目标为任务树 suggests substantive goal-driven decomposition. However, the function only classifies by keywords, selects a preset template, and fills it without using the context argument or adapting subtasks to the actual goal, creating a mismatch between documented intent and behavior.
