Add Claude Code commands for Rails development

[joshukraine]

Motivation

The current Claude Code setup has solid general-purpose commands (/commit, /create-pr, /review-pr, /resolve-issue, /update-deps, /test-drive, /new-project), but lacks commands tailored to the primary development workflow: Ruby on Rails.

Proposed commands

/refactor

Systematic code refactoring with test validation between steps:

• Analyze the target code for complexity, duplication, and design issues
• Propose refactoring steps with clear before/after expectations
• Run tests after each step to ensure nothing breaks
• Support common patterns: extract method, extract class, inline, rename, move

/debug

Structured debugging workflow:

• Analyze error output (stack traces, logs, test failures)
• Trace code paths through the application
• Identify root cause vs symptoms
• Suggest and apply fixes with test validation

/security-audit

Scan for common security issues, especially Rails-specific:

• Mass assignment vulnerabilities (strong parameters)
• SQL injection (raw SQL, find_by_sql, interpolation)
• CSRF protection gaps
• Insecure direct object references
• Open redirects
• Sensitive data exposure in logs/errors

Other improvements

• Update project CLAUDE.md to list available custom commands for discoverability
• Consider pre-allowing bundle, bin/rails, bin/rspec in Claude Code permissions for smoother Rails workflows
