-- **Custom instructions** (`.github/copilot-instructions.md`, `*.instructions.md`, `AGENTS.md`) that automatically apply context
-- **Custom agents** (`.agent.md`) — specialized AI personas with tailored expertise
-- **Agent Skills** (`.github/skills/<name>/SKILL.md`) — portable, specialized capabilities
-- **MCP server configurations** — extend Copilot CLI with external tools and services

-The intent is to keep everything **in-repo**, versioned, reviewable, and easy to reuse across projects.
