README

Layered Rails Skills

Design and review Rails applications using layered architecture principles from the [Layered Design for Ruby on Rails Applications](https://www.packtpub.com/en-us/product/layered-design-for-ruby-on-rails-applications-9781806114221) book.

The bundled plugins and slash commands target [Claude Code](https://docs.anthropic.com/en/docs/claude-code), while the core skill content (`SKILL.md` + workflows + references + examples) is also usable from other environments such as Codex.

**Install (recommended — full plugin with commands and sub-agents):**

/plugin marketplace add palkan/layered-rails-skills
/plugin install layered-rails@layered-rails-skills

**Commands:**

Command	Purpose
`/layered-rails:analyze`	Full codebase architecture analysis
`/layered-rails:analyze-services`	Audit `app/services/` — conventions, clusters, layer hygiene, test consequences
`/layered-rails:analyze-callbacks`	Score model callbacks, find extraction candidates
`/layered-rails:analyze-gods`	Find god objects via churn x complexity
`/layered-rails:review`	Review code changes for layer violations
`/layered-rails:spec-test`	Run specification test on specific files
`/layered-rails:plan [goal]`	Plan incremental adoption of layered patterns
`/layered-rails:archspec`	Generate and verify an `Archspec.rb` enforcing layer boundaries in CI

**Install via [skills.sh](https://skills.sh/) (skill content only — no slash-command bindings):**

npx skills add palkan/layered-rails-skills --skill layered-rails

skills.sh delivers the `skills/layered-rails/` tree — `SKILL.md`, `workflows/`, `references/`, and `examples/`. The `/layered-rails:*` slash commands and the `layered-rails-planner` / `layered-rails-reviewer` sub-agent registrations are not part of the skill spec and won't be copied, but every workflow they wrap is in `workflows/` and can be invoked by name in plain language ("run the layered-r
