Models behind the recomps

Coding agents sign their work: Claude Code adds a Co-authored-by line naming the exact model to every commit it makes, and Codex, Copilot and others leave their own marks. This page counts those lines across every listed project's commits since 24 Feb 2025.

Agent files, no credited commits (34 projects)

These keep instructions for a coding agent in the repo (CLAUDE.md, AGENTS.md, …) but no commit names a model — the trailers may be switched off or squashed away. A hint of which agent, not a count, so they are left out of the figures above.
