Japanese Translation And Tutor

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Japanese translation and tutoring skill that discloses its use of the SkillBoss API, with privacy considerations but no hidden or destructive behavior found.

Before installing, confirm you are comfortable sending text you ask it to translate or explain to SkillBoss using your SKILLBOSS_API_KEY. Avoid submitting confidential, regulated, or secret material unless that third-party processing is approved for your use.

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
95% confidence
Finding

The manifest description lists generic triggers such as "translate", "what does this say", and especially "help me understand", which overlap with common everyday requests outside the narrow Japanese-translation context. The trigger section does not include exclusion conditions or negative examples to clarify when the skill should not activate.

External Transmission

Medium
Category
Data Exfiltration
Confidence
90% confidence
Finding

The request includes a bearer token in the Authorization header while transmitting user content to an external service. Although using an API key is standard, the combination of third-party transmission and credentialed access means compromise of logs, error handling, or downstream systems could expose sensitive data or enable misuse of the service.

External Transmission

Medium
Category
Data Exfiltration
Confidence
88% confidence
Finding

The hardcoded external endpoint confirms that all submitted content is sent off-platform to SkillBoss. In the context of a translation skill, this is expected behavior, but it still represents a genuine security and privacy consideration because users may paste confidential Japanese text that leaves the host environment.
