Installation

gem "ruby_llm-skills"

Quick Start

chat = RubyLLM.chat
chat.with_skills
chat.ask "Create a PDF report from this data"

The LLM discovers skills, calls the skill tool, and gets instructions.

Usage

chat.with_skills                              # app/skills (default)
chat.with_skills("lib/skills")                # custom path
chat.with_skills("app/skills", "app/commands") # multiple paths
chat.with_skills("app/skills", user.skills)   # with database records

With RubyLLM::Agent (v1.12+)

class SupportAgent < RubyLLM::Agent
  model "gpt-5-nano"
  instructions "You are a support assistant."
  skills "app/skills", only: [:faq, :troubleshooting]
end

chat = SupportAgent.chat
chat.ask("How do I reset my password?")

agent = SupportAgent.new
agent.with_skills("extra/skills")
agent.ask("What can you help with?")

`agent.with_skills(...)` replaces the current skill tool configuration. To combine sources, pass all sources in a single `skills`/`with_skills` call.
