YC New Way

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only startup planning skill with proportionate guidance and no executable, persistence, credential, or hidden data-handling behavior.

Installers should expect this skill to influence startup-planning requests toward a YC-style validation sprint. Review generated plans before posting in communities, adding analytics, or collecting emails, and ensure any outreach complies with site rules and applicable privacy requirements.

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

Finding

The skill description includes broad activation phrases such as 'turn a vague idea into a testable plan' and 'design a 7-day startup sprint,' which can match many generic startup or planning requests. This creates over-broad routing risk: the skill may activate in contexts the user did not explicitly intend, causing the agent to apply this playbook inappropriately and potentially overshadow more suitable, narrower skills.
