kenkyu research

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward research API skill with disclosed external calls and no local code execution, though users should avoid sending sensitive queries unless they trust the kenkyu service.

Install only if you are comfortable sending research prompts to kenkyu.dev with your token and potentially spending account balance on runs. Avoid using it for secrets, confidential business material, personal data, or sensitive topics unless you have reviewed and trust the provider's data handling.

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

Confidence
94% confidence
Finding

The skill description says to use it for 'any question that benefits from a thorough, sourced investigation,' which is broad enough to trigger on many general prompts without clearly signaling that user queries will be sent to a third-party service. This increases the chance of accidental invocation on sensitive topics and unintended transmission of user data to an external API.

Missing User Warnings

Medium

Confidence
95% confidence
Finding

The markdown describes token-authenticated POST requests to an external API but does not warn that user queries, and potentially sensitive research topics, will be transmitted off-platform. Without an explicit warning or consent cue, users or calling agents may unknowingly send confidential information to a third party, creating privacy and data-handling risk.
