GitHub makes Agent Skills and MCP context generally available in code review
GitHub made repository Agent Skills and MCP-provided context generally available in Copilot code review. Existing cloud-agent MCP configurations carry over, GitHub and Playwright MCP servers are enabled by default, and review-time MCP calls are restricted to read-only tools.
Why it matters: External systems and repository procedures can now influence review conclusions, expanding the evidence, instruction, secret, and prompt-injection boundaries around automated review.
