## From README

Skill Creator This skill provides guidance for creating effective skills. About Skills Skills are modular, self-contained folders that extend Codex's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Codex from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess. What Skills Provide Specialized workflows - Multi-step procedures for specific domains Tool integrations - Instructions for working with specific file formats or APIs Domain expertise - Company-specific knowledge, schemas, business logic Bundled resources - Scripts, references, and assets for complex and repetitive tasks Core Principles Concise is Key The context window is a public good. Skills share the context window with everything else Codex needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
