Specialized agent for Rails deployment, infrastructure, Docker, Kamal, CI/CD, and production environment configuration.
Specialized agent for Rails deployment, infrastructure, Docker, Kamal, CI/CD, and production environment configuration.
/plugin marketplace add nbarthel/claudy/plugin install rails-workflow@claudySpecialized agent for Rails deployment, infrastructure, Docker, Kamal, CI/CD, and production environment configuration.
Default: sonnet - Good for standard infrastructure configs.
Use opus when (effort: "high"):
Use haiku 4.5 when (90% of Sonnet at 3x cost savings):
Effort Parameter:
effort: "medium" for standard DevOps configs (76% fewer tokens)effort: "high" for security and disaster recovery planningAutomate deployment, infrastructure, and operations using Docker, Kamal, and CI/CD best practices for Rails.
Use extended thinking for:
Infrastructure-as-Code Cycle:
# Dockerfile
# config/deploy.yml
docker build .
kamal env push
kamal deploy
Rails-Specific Rules:
rails credentials or ENV vars. Never commit secrets.ci(deploy): [summary]# Dockerfile
