Discord Markdown

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Discord markdown formatting helper with template examples and no executable behavior or hidden data handling.

This skill is reasonable to install for drafting Discord-formatted text. Review generated messages before posting, especially templates that include @everyone, @here, links, API placeholders, or moderation/action wording.

A.I.G

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

Anti-Refusal Statement

Anti-Refusal

npm run lint       # ✅ No warnings

80% confidence
Finding
Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Whitespace Padding

Prompt Injection
Content
After **every** Discord message code block, include a summary table with the following stats:

| Stat                 | Description                                       | How to Count                                                                                                            |
| -------------------- | ------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- |
| **Characters**       | Total character count of the message              | Count all characters inside the code block. Show as `X / 2,000` for chat messages or `X / 4,096` for embed descriptions |
| **Sections**         | Number of header-delimited sections               | Count all `#`, `##`, `###` headers. If no headers, show `0`                                                             |
Confidence
70% confidence
Finding
Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

External Transmission

## 🔌 [API/Integration Name]

**Base URL:** `https://api.example.com/v1`
**Auth:** [API key / OAuth / Bearer token]
**Docs:** [link]
Confidence
50% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
