Security audit

Investigation First

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed investigation workflow that encourages gathering evidence before decisions, with no hidden code, persistence, credential handling, or exfiltration behavior found.

Install this if you want an agent to investigate before making recommendations. Be aware that it encourages broad fact gathering, including reading code, checking logs or git history, and running tests, so give clear scope and avoid directing it at sensitive logs or private repositories unless that access is intended.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The file presents the skill primarily in Chinese and includes an English trigger line, but it does not state that the user may choose their preferred language or that the skill is limited to a Chinese-speaking context. This can create a language-policy issue because the skill appears to impose a locale/language presentation without explicit opt-in or justification.

Vague Triggers

Medium
Category

Confidence
95% confidence
Finding

The dispatch condition is very broad ('use when comprehensive fact gathering and analysis are needed'), which can cause the agent to be invoked in many loosely defined situations. Over-broad routing increases the chance of unnecessary tool use, scope creep, and investigation actions such as code inspection, log review, or command execution in contexts where a narrower, safer skill would suffice.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The description, headings, instructions, and output format are entirely in Chinese, implicitly requiring the skill to operate in that language. There is no opt-in, fallback, or statement that the skill is intended only for a Chinese-language or region-specific context, which makes this a natural-language locale policy issue.

Natural-Language Policy Violations

Confidence
88% confidence
Finding

The manifest description is entirely in Chinese and presents the skill as Chinese-source-material quotations, with no indication that language selection is optional. Under the policy rule, forcing a specific language or locale without user opt-in is a natural-language policy concern unless the constraint is explicitly justified.
