Agent Friendly Code

Which public repos are easiest for Claude Code to work in?

Repos from GitHub, GitLab, and Bitbucket, ranked by their Claude Code score rather than the average across every agent. gitlab-org/cli leads with 98.0.

The methodology lists the weight Claude Code gives each check and the documentation it comes from.

Claude Code — Loads CLAUDE.md at the start of every conversation per Anthropic's memory docs, so AGENTS.md / CLAUDE.md and a fast test loop carry the most weight.
