ruby-version
Verify what Ruby versions actually exist and install a specific Ruby via rbenv. Use BEFORE asserting that any Ruby version does or doesn't exist (e.g., "Ruby 4.0 isn't out yet", "the latest Ruby is 3.x", "Ruby X.Y.Z doesn't exist"). Also use when the user asks "what's the latest Ruby", "is Ruby X out", "does Ruby X.Y exist", "install Ruby", "switch to Ruby X", "what Ruby is installed", or mentions a specific Ruby version you're unsure about. Claude's training data may be out of date — run `check.sh` first.

Review and update existing Rails controllers and generate new controllers following professional patterns and best practices. Covers RESTful conventions, authorization patterns, proper error handling, and maintainable code organization.
development5
document-this
Generate multi-audience documentation from any codebase — workflows for non-technical readers, architecture for developers, and AI orientation for agents. Deterministic JS scripts handle structural extraction; the agent writes the prose. Project-agnostic and self-orienting. Use when the user asks to "document this project", runs `/document-this`, runs `/document-this <file-path>`, or wants fresh documentation reflecting the current codebase state.
development5
frontend-patterns
Frontend patterns for Rails applications using Slim templates, Stimulus JavaScript framework, CSS with Optics utilities. Use when building views, adding interactivity, styling components, or when the user mentions Slim, Stimulus, JavaScript, CSS, or frontend development.
development5
json-typed-attributes
Define typed attributes backed by JSON fields in Rails models. Use when models need flexible data storage with type casting, validations, and form integration. Supports integer, decimal, string, text, boolean, date, and array types.
testing5
laws-of-ux
Review and guide UI implementations using the 21 Laws of UX. Identifies usability issues in HTML, CSS, and JavaScript by applying established cognitive, visual, and behavioral principles. Use when reviewing UI code, building new interfaces, or auditing user experience.
development5
optics-context
Use the Optics design framework for styling applications. Apply Optics classes for layout, spacing, typography, colors, and components. Use when working on CSS, styling views, or implementing design system guidelines.
development5
rails-audit
Perform comprehensive code audits of Ruby on Rails applications based on thoughtbot best practices. Use this skill when the user requests a code audit, code review, quality assessment, or analysis of a Rails application. The skill analyzes the entire codebase focusing on testing practices (RSpec), security vulnerabilities, code design (skinny controllers, domain models, PORO with ActiveModel), Rails conventions, database optimization, and Ruby best practices. Outputs a detailed markdown audit report grouped by category (Testing, Security, Models, Controllers, Code Design, Views) with severity levels (Critical, High, Medium, Low) within each category.
development5
testing-patterns
Write automated tests using RSpec, Capybara, and FactoryBot for Rails applications. Use when implementing features, fixing bugs, or when the user mentions testing, specs, RSpec, Capybara, or test data. Avoid using rails console or server for testing.
testing5
usability-heuristics
Audit UI implementations against Nielsen's 10 Usability Heuristics for User Interface Design. Produces a structured issue log with severity ratings, heuristic mappings, and remediation guidance. Use when conducting heuristic evaluations, reviewing UI code for usability compliance, or auditing existing interfaces.
development5
sentry-fix-issues
Find and fix issues from Sentry using MCP. Use when asked to fix Sentry errors, debug production issues, investigate exceptions, or resolve bugs reported in Sentry. Methodically analyzes stack traces, breadcrumbs, traces, and context to identify root causes.
tools5
rm-sentry-issue-fixer
Find and fix issues from Sentry using MCP. Use when asked to fix Sentry errors, debug production issues, investigate exceptions, or resolve bugs reported in Sentry. Methodically analyzes stack traces, breadcrumbs, traces, and context to identify root causes.
tools5
theming-context
Using Optics for implementing design system guidelines, theming, and color scales.
documentation5
sentry-top-issue
Pick the single highest-priority unresolved Sentry issue and hand it off to a fixer skill. Use when triaging Sentry errors, running automated issue triage, or when asked to fix the top Sentry issue in a project.
tools5
turbo-fetch
Implement dynamic form updates using Turbo Streams and Stimulus. Use when forms need to update fields based on user selections without full page reloads, such as cascading dropdowns, conditional fields, or dynamic option lists.
tools5
skill-creation
Create and update SKILL.md files following the Agent Skills format specification. Use when building new skills or improving existing skill documentation for AI agents.
development5
stimulus-controllers
Create and register Stimulus controllers for interactive JavaScript features. Use when adding client-side interactivity, dynamic UI updates, or when the user mentions Stimulus controllers or JavaScript behavior.
tools5
routing-patterns
Review, generate, and update Rails routes following professional patterns and best practices. Covers RESTful resource routing, route concerns for code reusability, shallow nesting strategies, and advanced route configurations.
development5
dynamic-nested-attributes
Implement Rails nested attributes with dynamic add/remove functionality using Turbo Streams and Simple Form. Use when building forms where users need to manage multiple child records (has_many associations), add/remove nested items without page refresh, or create bulk records inline.
development5
form-auto-save
Automatic form submission after user input changes using a debounce mechanism to prevent excessive server requests. Creates a seamless auto-save experience for forms with rich text editors or multiple fields.
data-ai5
trace
Trace code through the stack — upward to entry points, downward to data, or laterally across boundaries. Use when the user asks "where does this get called from", "what calls this method", "trace this through the stack", "how does this request flow", "where does this data come from", "follow this through the code", or pastes/selects a piece of code and wants to understand where it fits in the larger system.
development5
create-profile
Creates or updates a personal developer profile at ~/.claude/PROFILE.md. Run this once to tell Claude about your role, experience, and preferences so that explanations and other skills can tailor their output to you.
development5
explain
Explains features, terms, and concepts from a codebase. Use whenever the user asks to explain, describe, or understand something ("explain X", "what is X", "how does X work"). Also use when starting an implementation, refactor, or test task — invoke as `depth:pamphlet <concept>` before writing code, `depth:novella <concept>` before designing an approach, or `depth:novel <concept>` before a deep refactor. Agent-triggered mode (depth: prefix) skips the interview and returns a structured WHAT/WHERE/HOW/CONNECTS TO block instead of a narrative.
development5
brave-breakdown
Use this skill to guide a developer or designer through a BRAVE framework breakdown of a task before they start work. Trigger whenever someone wants to think through a ticket, break down a card, plan their approach before starting, validate a task before picking it up, or prepare a breakdown to share with a teammate or client. Also trigger for any of these phrases or close variations: "BRAVE this", "brave it", "break down this card", "think through this ticket", "help me plan this out before I start", "want to make sure I understand this before I start coding", "want to revalidate this card", "help me think through this before my standup/meeting", or "I'm about to pick up a card and want to break it down". If someone mentions starting work on a card and wants help planning, validating, or understanding it first — this skill should run.
