Deep Research Executor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed research-reporting workflow that searches the web and writes report files, with no evidence of hidden execution, credential access, exfiltration, or destructive behavior.

Before installing, expect this skill to perform broad web research, generate Markdown reports in English by default, save them under report/, and update index.md. Use it in a workspace where those report files and index entries are desired, and explicitly tell the agent if you need another language or do not want files written.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (3)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill says reports must be generated in English, and later repeats 'Write in English,' which forces a specific language regardless of user preference. This is a natural-language policy concern because no opt-in, fallback, or justification for the language restriction is provided.

Missing User Warnings

Medium

Confidence
94% confidence
Finding

The skill explicitly instructs the agent to create a report file and append an entry to index.md, which causes persistent workspace modification without any requirement for user awareness or consent. In an agent setting, silent file writes can overwrite content, pollute repositories, or create misleading artifacts, especially when combined with web-sourced content and dynamic filenames.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This line explicitly requires the final report to be written in English. Because the skill also supports non-English input and bilingual search, the fixed English-output rule is a locale/language restriction that is not presented as optional or justified.
