Score for each AI agent

Each agent looks for different things in a repo, based on its own docs. Under each score are the three checks it cares about most; the agent's name links to its leaderboard. How each agent is scored →

Does JetBrains/compose-multiplatform have agent instructions?

An AGENTS.md (or CLAUDE.md) at the root tells AI coding agents how to build, test and work in the repo. A few agents also read a file of their own.

AGENTS.md / CLAUDE.md
None at the root (no AGENTS.md, CLAUDE.md or AGENT.md)
Agent-specific files
None: no GEMINI.md, .cursor/rules, .openhands/setup.sh or .aider.conf.yml
