Summary

What changed

GitHub released Copilot CLI v1.0.48-0 with prompt-flow and headless-mode fixes, including MCP behavior changes for Azure DevOps-only workspaces.

Why it matters

Headless and prompt-mode reliability is where coding agents either become automation tools or remain interactive demos. These fixes show GitHub is still hardening Copilot CLI for mixed enterprise environments instead of assuming a single GitHub-native workflow.

Evidence excerpt

Copilot CLI v1.0.48-0 fixes /ask follow-up behavior, removes YAML frontmatter from injected skill content, and auto-disables the built-in github-mcp-server in Azure DevOps-only workspaces for prompt and headless mode.
