Documentation Overview

Rails Agent Skills

A catalog of 28 Rails skills and 9 personas that teach agents how to test, implement, and review Rails work. Process skills (TDD gates, YARD, DDD, service objects) live in ruby-core-skills. Install both.

Write the test → run it → confirm it fails for the right reason → implement → confirm it passes

Name the persona when you want the whole chain: tdd, bug-fix, graphql, migration, background-job, engine, review, quality, setup.

See docs/persona-guide.md and docs/personas/.

Catalog

Area	Skills
Testing	`plan-tests`, `write-tests`, `test-service`
Quality	`code-review`, `security-check`, `review-architecture`, `apply-code-conventions`, `apply-stack-conventions`, `implement-authorization`, `refactor-code`
Engines	`create-engine`, `test-engine`, `document-engine`, `review-engine`, `release-engine`, `create-engine-installer`, `extract-engine`, `upgrade-engine`
Infrastructure	`review-migration`, `implement-background-job`, `seed-database`, `optimize-performance`, `version-api`, `implement-hotwire`
API	`generate-api-collection`, `implement-graphql`
Context	`load-context`, `setup-environment`

Core skills (install separately): triage-bug, respond-to-review, write-yard-docs, create-service-object, integrate-api-client, define-domain-language, model-domain, skill-router, and the process skills.

Full list: docs/reference/skill-catalog.md. Gaps: docs/reference/gaps.md.

Install

There is no root SKILL.md. Each folder under skills/ is its own skill, so the CLI can prompt for all or one.

bash

# picker: all skills, or a subset
npx skills add igmarin/ruby-core-skills
npx skills add igmarin/rails-agent-skills

# all skills, skip prompts
npx skills add igmarin/ruby-core-skills --skill '*'
npx skills add igmarin/rails-agent-skills --skill '*'

# one skill
npx skills add igmarin/rails-agent-skills --skill load-context

Or with GitHub CLI v2.90.0+ (gh skill):

bash

gh skill install igmarin/ruby-core-skills
gh skill install igmarin/rails-agent-skills
gh skill install igmarin/rails-agent-skills code-review --scope project

A PromptScript global-install warning from skills.sh is harmless. The skills still install for other hosts.

A guidance signal from public completeness & health data — not a user rating. New listings start lower and rise as they add docs, get verified, and grow adoption. Signals we can't observe for a listing are skipped, not counted against it.
