Multi-Agent Collaboration Communication

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation and template skill for designing multi-agent workflows, with no evidence of hidden execution or data theft.

Use this as a design and template aid. Before applying its examples to real systems, confirm which agents or services will receive repository diffs, author emails, credentials, or business data, and avoid placing real secrets in the provided protocol examples.

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

Without declared permissions the skill's intent is opaque and cannot be validated.

Finding

The activation language is very broad and encourages use for many 'multi-agent collaboration and communication scenarios' without clear boundaries, exclusions, or safety constraints. In an agentic environment, this can cause over-triggering in contexts involving code generation, workflow automation, or distributed coordination, increasing the chance the skill is applied where it is not appropriate and leading to unsafe or overly empowered behavior.

Missing User Warnings

Confidence

Finding

This markdown file includes a communication protocol where code_changes and metadata such as author email, commit ID, and branch are shared in messages between agents. The description does not include any warning about privacy, sensitive repository contents, or data-handling implications, which is expected for markdown files describing behavior that could affect user data.
