Lel Mail

ยท v1.1.4

High Risk

Send and read email via a combination of python and bash scripts which makes use of the main agent for reasoning and logic. This skill enables the agent to write to memory based on contents in the email and to reach out to the user either to notify them of happenings or to request inputs to respond. This skill also contains a python script to read and manage the email queue containing functionality to list pending outgoing emails and delete emails before they can be sent out. Please note that this skill enables the agent to act upon received emails by adding to agent memory and sending responses

๐Ÿ”’ Containment

Level: maximum

Required:
  • SANDBOX_CONTAINER: Code execution capability
Recommended:
  • LOG_ACTIONS: Audit trail for all actions

โšก Risks

Unauthorized tool use: MCP_SYS_CRITICAL_ACCESS high

Mitigation: Avoid accessing system directories unless absolutely necessary.

Command injection risk: MCP_SQL_BLIND high

Mitigation: Remove SQL exploitation patterns.

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: INSTRUCTED_SENSITIVE_SERVICE_ACCESS high

Mitigation: Clearly document which sensitive services are accessed and why; use minimal required permissions
