GitHub's per-model breakdown (08-11), Copilot on web's clickable token-spend indicator showing per-session and per-message quota (08-10), Devin Desktop displaying ACU usage in-client (08-10), Claude Code adding gateway spend-limit support with reset times (08-08) (GitHub Changelog).

Anthropic invented a file convention. It's now shipping GA inside a competitor's product. Nobody wrote a spec, nobody held a standards meeting, it just happened. On July 29, GitHub made agent skills and MCP server support generally available in Copilot code review for all Pro,...
