Rails AI Agents

A production-ready Claude Code setup for Ruby on Rails development: 19 specialized agents, 26 slash commands (including the SDD kit), 18 skills, 14 rules (11 path-scoped + 3 always-on), 1 MCP, and 6 lifecycle hooks. Drop it into your project and your AI assistant instantly knows Rails conventions, TDD workflows, and production patterns.

Also includes:

• Spec Driven Development (SDD) kit — a full specification-to-implementation pipeline + lightweight mode for bug fixes.
• a separate 37signals-style conventions pack (.claude_37signals/) for teams that prefer rich models + Minitest over the default layered setup.
• Claude Code Extensibility Guide
• and more!

Latest Updates

• Add caveman rule with full intensity level (token reduction)
• Add plan, review, and PR artifact commands.
• Add tmux session launcher script for Rails development.

Quick Start

# Most projects: copy the default .claude/ directory into your Rails project
cp -r .claude/ /path/to/your-rails-app/.claude/

.specify/ is optional unless you want the SDD workflow. .claude_37signals/ is currently a conventions pack (instructions, agents, skills, rules, settings), while the slash-command set documented below lives under .claude/commands/.

OpenAI Codex and GitHub Copilot Support

This repo includes a practical setup for both OpenAI Codex and GitHub Copilot (including different Copilot-backed models such as GPT, Claude, and Gemini), while keeping .claude/ as the canonical source.

• AGENTS.md is the shared high-level project instruction file.
• .agents/skills/ is the mirrored skills directory used by Codex and reusable from Copilot.
• .claude/skills/ remains the canonical source for shared skills.
• .github/copilot-instructions.md is the Copilot entrypoint.
• .github/instructions/claude-rules/ contains generated path-scoped bridge files that point back to .claude/rules/.

Because Codex skill discovery is currently unreliable with symlinks, this repo includes a local sync script that copies Claude skills into real directories:

scripts/sync_claude_skills_to_codex.sh
scripts/sync_claude_rules_to_copilot.sh

Run these scripts after adding, removing, or renaming any skill or rule. If Codex or Copilot is already running, restart or reload the chat session to pick up updates.
