Add MP Expert custom Copilot agent for Mixpanel documentation Q&A

[Copilot]

Creates a custom GitHub Copilot agent to help Mixpanel customers, support teams, and employees navigate the documentation.

Changes

• .github/agents/mp-expert.agent.md: Agent configuration with YAML frontmatter defining tools (read, search, view) and comprehensive instructions covering:

  • Friendly, customer-focused tone for semi-technical audiences
  • Expertise in core concepts (Events, Users, Properties), implementation, analytics, and advanced features
  • Clear boundaries: documentation Q&A only, no code modification or production system access
  • Accurate references to repository structure (/pages/docs/, /pages/guides/, /reference/)

• README.md: Usage documentation for accessing the agent via @mp-expert in GitHub Copilot Chat

Usage

@mp-expert How do I track custom events in my mobile app?
@mp-expert What's the difference between a cohort and a segment?
@mp-expert Can you explain how funnel reports work?

The agent searches and references official documentation to provide accurate, contextual answers.

Original prompt

Study the official GitHub documentation for creating custom agents at: https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/create-custom-agents

Then create a "MP Expert" custom agent for this documentation repo. This agent's purpose is answer questions about how to use and implement Mixpanel based on the documentation in this repo. This is agent's purpose is NOT to assist with the technical development of this documentation system itself. This agent's is intended to assist consumers of Mixpanel's public facing docs. Mixpanel customers, Mixpanel customer support and other Mixpanel employees who are searching and reading these docs at docs.mixpanel.com should be able to come to GitHub Copilot, select this agent and ask questions. This agent is an interactive guide to the information contained in these docs. It should have a friendly, customer focused tone. It should explain things clearly and with a semi-technical audience in mind, not just software engineers.
