Does Copilot read my CLAUDE.md?

Yes — GitHub's docs say Copilot accepts a single CLAUDE.md or GEMINI.md at the repository root, alongside its own .github/copilot-instructions.md and AGENTS.md files.

What changed in Copilot billing in 2026?

From June 1, 2026, paid Copilot plans include GitHub AI Credits instead of premium requests, and a Max plan was added at $100/month. The request-based model remains only for some annual subscribers.

Can Claude Code replace Copilot?

For agentic, multi-file tasks it can. For inline completions while you type in an editor, Copilot (or Cursor) covers what a terminal agent does not. Many teams use both.

Comparison

Claude Code vs GitHub Copilot for AI coding

Claude Code is Anthropic's agentic coding tool. GitHub Copilot is GitHub's assistant, with completions, chat, a CLI and a cloud agent across many vendors' models. Copilot moved to credit-based billing in June 2026.

How you pay

Claude Code comes with Claude Pro ($20/month), Max (from $100/month) and Team seats, or runs on an API account billed per token.

Copilot has Free, Pro ($10/month), Pro+ ($39), a new Max plan ($100), Business ($19 per seat) and Enterprise ($39 per seat). Since June 1, 2026, paid plans include a monthly allowance of GitHub AI Credits instead of premium requests; annual subscribers who stayed on the old model are billed under the legacy request pricing.

The instruction files each one loads

Claude Code loads CLAUDE.md from your project and parent folders at the start of every session, a user-level file in ~/.claude, and rules in .claude/rules/. It also reads AGENTS.md when no CLAUDE.md exists.

Copilot reads .github/copilot-instructions.md, path-scoped files in .github/instructions/, and AGENTS.md anywhere in the repo (the nearest one wins). It also accepts a single CLAUDE.md or GEMINI.md at the repo root — so a repository already set up for Claude Code gives Copilot its instructions too.

Which to choose

Copilot fits teams that live in GitHub and want completions, review and a cloud agent under one seat price with a choice of models. Claude Code fits developers who want a terminal agent built around Anthropic's models. Because Copilot reads CLAUDE.md and AGENTS.md, running both from one instruction file is straightforward — and a bloated file costs you in both.
