Prd Cross Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward PRD analysis helper that reads local product and API reference material and writes a requirements document, with no hidden execution or persistence found.

Install this only in workspaces where the referenced competitor documents, API references, and optional Feishu destination are appropriate for the agent to use. The main thing to review is whether exposing those local paths and related skill names is acceptable for your environment.

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
  • 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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
Findings (5)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The manifest description is entirely in Chinese and frames the skill's purpose and applicability only in that language. Elsewhere the document also specifies Chinese trigger phrases and output style, but nowhere offers the user a language/locale choice, which is a natural-language policy concern under the locale/language rule.

Content

No source excerpt is available for this finding.

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
89% confidence
Finding

The skill explicitly enumerates internal skill names and repository paths, which discloses implementation details about available agent capabilities and local data layout. An adversarial user could use this information to steer the agent toward sensitive internal resources, craft follow-on prompts targeting those skills, or map the environment for broader prompt-level abuse.

Confidence
89% confidence
Finding

This line reveals another internal skill identifier and reference path, contributing to capability enumeration and environment mapping. In an agent ecosystem, such disclosure lowers the effort needed for an attacker to discover adjacent data sources and chain prompts toward unintended reads of internal documentation or API reference corpora.

Confidence
89% confidence
Finding

By naming the internal skill and data path for another platform integration, the document exposes the structure of the agent's local knowledge base. While not a direct compromise on its own, this materially assists reconnaissance and can increase the blast radius of prompt injection or data-exfiltration attempts against connected skills.

Agent Snooping
Confidence
89% confidence
Finding

This finding discloses the existence and location of an additional internal fetcher skill and its references directory, further expanding the attacker's map of the system. In context, the skill is designed to load local documents and API references, so revealing those exact targets makes the environment more dangerous by simplifying targeted prompt requests for internal content.
