Telegram Markdown Adapter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a formatting guide for making Markdown-style text render well in Telegram, with no executable code, install actions, persistence, or hidden data access.

Install only if you want Telegram-specific formatting behavior. If you do not want Chinese phrasing or emoji-style formatting, tell the agent to follow your preferred language and tone when using the skill.

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

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The manifest description includes Chinese instructional text inline with the English trigger and usage description, indicating a fixed bilingual/Chinese presentation rather than an explicit user-selected language option. The file does not document that language choice is optional or limited to a justified locale-specific deployment, which can violate language/locale policy requirements.

Natural-Language Policy Violations

Low
Confidence
79% confidence
Finding
The line states that the Chinese phrase `- 待办：...` is acceptable as part of the formatting guidance. This introduces a specific language choice into default output behavior without indicating that the user requested Chinese or that the skill is region-specific.
