elastic/elasticsearch-ruby/AGENTS.md

Always use bundle and rake commands, not any third-party packaging tools. rake test:client must pass before you commit code. Integration tests require Elasticsearch running on localhost:9200. They are skipped automatically if no server is available, so a failing integration test in CI always means a real failure. This repo contains two subprojects, each with its own Gemfile and Rakefile: Top-level Rakefile and rake_tasks/ orchestrate tasks across all subprojects. If a specific action you learned to do better will be useful…

CLAUDE.md vs AGENTS.md

Agent instruction files

What are agent instruction files?

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.

CLAUDE.md or AGENTS.md?

CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.

What is a skill?

A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.

Can I search my own team's files too?

Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
