Claude Code · Ruby defaults

## Summary
Agent: Claude Code  
Language: Ruby + Rails  
Intent: Keep prompts focused and approve architectural changes explicitly.

## Global rules
- Always refer to `config/application.rb` when adding new load paths.
- Validate configuration changes by running the default test suite before editing rule sets.

## Agent-specific
- Use Claude's structured output when listing steps, but keep prompts under 300 tokens.
- Ask for confirmation before refactoring public controller actions.

## Language-specific
- Prefer `sorbet` annotations when documenting complex interfaces.
- Favor keyword arguments in service objects and avoid mutable globals.

## Framework-specific
- Keep controllers lightweight; move business logic into `app/services`.
- Reuse shared view components in `app/components` for layout consistency.

## Options
- Token saving: Cache prompts in `AGENT.md` snippets; reuse them instead of rewriting.
- Testing: Always update or add specs under `spec/` when application behavior changes.
- Security: Never commit credentials or tokens; use Rails `credentials` for secrets.
