Messaging

MCP Agent Mail enables multiple AI coding agents to coordinate asynchronously through a mail-like system. It provides inbox/outbox messaging, file reservations to prevent conflicts, and contact management, with all communications stored in Git for human auditability.

This skill should be used when user asks to "search Slack for messages", "find Slack messages about X", "get channel history", "look up conversation in Slack", or "find what someone said in Slack".
