Agent Friendly Code

Which public repos are friendliest to an AI coding agent?

Ranked per model across GitHub, GitLab, and Bitbucket — because agents aren't interchangeable.

Looking up a dependency? Check any npm / PyPI / Cargo package by name.

Repo not on the board? Score any public GitHub repo live from its current commit.

GPT-5 Codex — Reads AGENTS.md before doing any work per OpenAI's Codex docs. Hierarchical (per-directory) AGENTS.md and AGENTS.override.md are first-class.
