Copilot Code Review Reads Your MCP Servers and Team Style Guides — GA July 29

GitHub's Copilot code review shipped agent skills (SKILL.md) and MCP server connections on July 29 — your automated reviewer now knows your internal tools and team standards, not just the diff.

Two new capabilities reached GA for all Copilot Pro, Pro+, Business, and Enterprise users on July 29:

Agent skills — create .github/skills/<name>/SKILL.md with natural-language instructions about your codebase's patterns, and Copilot review invokes them for every PR. One file can encode "we never call the legacy billing API directly" or "every new SQL query goes through our retry wrapper." Reviews now label which comments came from a skill, so the source is transparent.

MCP connections — pull read-only context from your issue tracker, service catalog, or docs system into the review. All MCP tool calls are limited to read-only (Copilot cannot write back). Any MCP config already wired for the Copilot cloud agent applies automatically to code review — no duplicate setup.

Why it matters: Copilot reviews can finally enforce team-specific conventions, not just general code quality — closing the gap with what a senior engineer who knows your codebase actually catches.
