Ruby Harness
The ask-rb harness family, for any Ruby project — not just Rails.
ask-ruby-harness — An admin AI copilot for plain Ruby projects (gems, Sinatra, Roda, scripts). Gives AI agents safe, structured access to your database, models, logs, commands, and tests — with no Rails dependency. It is the language edition of the harness: ask-rails-harness builds on it and adds the Rails-native surface (engine, routes).
ask-ruby-harness-mcp — Exposes the same tools to any MCP-compatible coding agent (Claude Code, Cursor, ZCode, …) over stdio. Serve the project in your working directory — works in monorepos.
