Score for each AI agent
Each agent weighs the checks by its own docs. Under each score are its top three. How each agent is scored →
Does ReactiveX/RxJava 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, AGENT.md, .claude/CLAUDE.md or .claude/AGENTS.md)
- Agent-specific files
- None: no GEMINI.md, .cursor/rules, .openhands/setup.sh, .aider.conf.yml or .agents/skills

# AGENTS.md
Guidance for AI coding agents working in ReactiveX/RxJava. RxJava – Reactive Extensions for the JVM – a library for composing asynchronous and event-based programs using observable sequences for the Java VM. Written mainly in Java.
## Where things are
- Dependencies are declared in `build.gradle`.
- Tests live in `src/test`.
- Lint and format rules are configured in `config/checkstyle/checkstyle.xml`.
- CI is defined in `.github/workflows`; read it for the exact install, lint and test steps.
- Use the `./gradlew` wrapper, not a system install.
- Follow the conventions in `CONTRIBUTING.md`.
## Commands
