Security audit

Skill Combo - 技能组合器

Security checks for vulnerabilities and agentic risk

Overview

This skill is not overtly malicious, but it broadly orchestrates and dynamically loads other installed skills without clear enough consent, scoping, or capability limits.

Install only if you are comfortable with a meta-skill coordinating other installed skills. Prefer explicit slash triggers, review which subskills it will run, and confirm any action that can create reminders, modify state, use credentials, or call external services.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
Findings (6)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill documentation is written entirely in Chinese and includes Chinese-only trigger and usage text, but it does not state that the skill is intended only for Chinese-speaking users or provide an opt-in language choice. Under the language/locale policy, a skill should not implicitly force a specific language unless that constraint is clearly justified or optional.

Finding

SQP-3 applies to all file types and covers language or locale policy violations. The document is presented entirely in Chinese and names Chinese trigger phrases, but it does not state that users may choose another language or that the Chinese-only behavior is intentional and justified.

Missing User Warnings

Confidence

Finding

The skill markets itself as a collaboration engine, but its documented behavior includes creating reminders and executing other skills, both of which can affect system state or trigger privileged actions. Without clear disclosure and consent boundaries, users may unknowingly authorize side effects, especially when combined skills inherit broader capabilities than the top-level description suggests.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly describes loading arbitrary skill files by name, reading their content, and dynamically importing them for execution. That turns a 'combo/orchestration' feature into a generic code-loading mechanism, so any unsafe or malicious downstream skill can be invoked transitively, greatly expanding execution scope and bypassing the user's expectation of a simple coordination tool.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
82% confidence
Finding

The manifest presents the display name, description, keywords, and categories primarily in Chinese, with no indication that users can choose another language or locale. This can constitute a language-policy issue when a skill implicitly assumes a specific language without documenting opt-in or regional restriction.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The trigger word set includes very generic phrases such as "多技能" and "技能组合", which are likely to appear in normal discussion unrelated to intentional skill invocation. In a meta-skill that coordinates multiple other skills, accidental activation is more dangerous than usual because it may broaden the scope of actions taken or cause unintended orchestration of other capabilities.
