SocialKit Discord Post

Security checks for vulnerabilities and agentic risk

Overview

This skill posts approved messages and attachments to Discord through a clearly disclosed channel webhook.

Review the separate socialkit-social-core dependency before use. Keep the webhook secret and limited to the intended channel, inspect the exact message and attachments, and approve them yourself in your terminal. All bundled files were inspected; the external core dependency remains outside this review.

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
