YouTube Upload Monitor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed YouTube upload monitoring helper that uses a third-party transcript API key and does not ship executable code.

Install only if you intend to use BulkTranscripts for YouTube upload monitoring. Keep BULKTRANSCRIPTS_API_KEY private, avoid pasting it into logs or shared chats, and be aware transcript and account requests are sent to bulktranscripts.co and may consume credits except where the skill identifies free endpoints.

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

Missing User Warnings

Medium
Confidence
88% confidence
Finding
The skill instructs the agent to obtain and use a third-party API key and send authenticated requests to an external service, but it does not include an explicit warning about credential handling, external transmission, or user consent boundaries. In an agent setting, this can lead to users providing sensitive credentials without understanding where they are sent or how they are stored, increasing the risk of accidental secret exposure or unauthorized third-party data sharing.

Vague Triggers

Low
Confidence
81% confidence
Finding
The description says to use the skill when a user 'wants alerts or digests for new uploads' or 'wants to track competitors' channels,' which are broad natural-language situations rather than specific trigger phrases or constrained activation rules. In a markdown skill description, this can create ambiguity about when the skill should activate versus when other monitoring or summarization skills might be more appropriate.
