Agent Messaging is a production-ready Claude Code skill (quality score 70/100) in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/agent-messaging/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user asks to "send a message to an agent", "check agent inbox", "message another agent", "reply to a message", "notify an agent", or any inter-agent communication task.
The Agent Messaging skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure.
