Tech Blog Writing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward technical blog-writing helper that creates a standalone HTML article file, with no evidence of hidden execution, credential access, network use, or persistence beyond the requested output file.

Install this if you want blog posts generated as standalone local HTML files. Check the output path and filename before use if overwriting files matters, and specify the desired language in your prompt if you do not want Chinese-language output.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium

Not specified by scanner
Confidence
95% confidence
Finding

The instructions are written to produce content as a Chinese-language technical blog writer and do not provide a user opt-in or alternative language behavior. This can violate language/locale policy because it imposes a specific language regardless of user preference.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly instructs the agent to render output to a standalone HTML file, which is a filesystem write side effect, without any requirement for user consent, confirmation, or clear disclosure. In an agent environment with file-write capability, this can cause unexpected persistence of generated content, overwriting existing files, or creating artifacts the user did not intend to store.
