This skill should be used when writing Ruby and Rails code in DHH's distinctive 37signals style. It applies when writing Ruby code, Rails applications, creating models, controllers, or any Ruby file. Triggers on Ruby/Rails code generation, refactoring requests, code review, or when the user mentions DHH, 37signals, Basecamp, HEY, or Campfire style. Embodies REST purity, fat models, thin controllers, Current attributes, Hotwire patterns, and the "clarity over cleverness" philosophy.
Writes Ruby/Rails code in DHH's 37signals style with fat models, thin controllers, and REST purity. Triggers on Ruby code generation, refactoring requests, or mentions of DHH/37signals/Basecamp style.

"The best code is the code you don't write. The second best is the code that's obviously correct."
Vanilla Rails is plenty:

Verbs: card.close, card.gild, board.publish (not set_style methods)
Predicates: card.closed?, card.golden? (derived from presence of related record)
Concerns: Adjectives describing capability (Closeable, Publishable, Watchable)
Controllers: Nouns matching resources (Cards::ClosuresController)
Scopes:
chronologically, reverse_chronologically, alphabetically, latestpreloaded (standard eager loading name)indexed_by, sorted_by (parameterized)Instead of custom actions, create new resources:
POST /cards/:id/close → POST /cards/:id/closure
DELETE /cards/:id/close → DELETE /cards/:id/closure
POST /cards/:id/archive → POST /cards/:id/archival

<success_criteria> Code follows DHH style when:
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
