Security audit

qa-test-leadership

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly QA leadership guidance, but it recommends an unpinned external install that could change a user's installed skill set.

Review the external `Kokxi/qa-test-skills` package before running the recommended install command, and prefer a pinned or verified version. The included skill content itself is guidance-only and low privilege, but the broader installation could change future agent behavior.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The activation criteria are very broad, covering generic terms like team management, performance evaluation, hiring, interviews, and goals. Overly broad triggers can cause the skill to activate in unrelated contexts, increasing the chance that users receive unintended instructions or that the skill overrides a more appropriate, narrower skill.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The primary skill description and operating guidance are written as prescriptive Chinese-language instructions, while the file does not state that language is optional or region-specific. This can violate language or locale policy when users have not opted into Chinese output.

Confidence

Finding

The skill recommends installing an external package via npx skills add Kokxi/qa-test-skills without pinning a specific version or commit. This creates a supply-chain risk: a later package update, account compromise, or repo change could cause users to fetch and run unexpected code or content under the trusted skill workflow.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The file presents the skill guidance entirely in Chinese and does not state that the language is optional, user-selected, or limited to a justified region-specific context. Under the policy rule for natural-language constraints, this can be treated as a locale/language restriction without explicit opt-in.
