Prompt Craft

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-design guidance skill with no bundled code, network behavior, credential handling, or hidden persistence; its main risks are usability and write-scope clarity.

Before installing, confirm you are comfortable with a Chinese-first prompt-design guide and use it only when intentionally creating or improving prompts, skills, or agent orchestration. When it generates files, review the draft and destination path before permitting any write or overwrite.

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
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill content is written primarily in Chinese and effectively prescribes Chinese-language prompt structures without stating that language should follow user preference. In a prompt-design skill, this can cause unintended language switching, reduce user comprehension, and propagate inaccessible or incorrect prompts into downstream agent workflows.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger guidance uses broad phrases like creating skills, optimizing prompts, designing agents, or orchestration, which are common requests and can cause the skill to activate in situations where the user did not intend it. Over-broad auto-loading increases the chance of incorrect routing, prompt interference, and unintended application of this skill's rules to unrelated tasks.

Missing User Warnings

Category

Confidence
84% confidence
Finding

The workflow says the final SKILL.md is written to disk as a completion condition, but it does not require explicit user consent before modifying files. In agent environments, undocumented write behavior can surprise users and lead to unintended local changes or overwriting artifacts.
