Description

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations.

Advanced features

• Form filling: See FORMS.md for complete guide • API reference: See REFERENCE.md for all methods • Examples: See EXAMPLES.md for common patterns ` Codex loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed. Pattern 2: Domain-specific organization For Skills with multiple domains, organize content by domain to avoid loading irrelevant context: ` bigquery-skill/ ├── SKILL.md (overview and navigation) └── reference/ ├── finance.md (revenue, billing metrics) ├── sales.md (opportunities, pipeline) ├── product.md (API usage, features) └── marketing.md (campaigns, attribution) ` When a user asks about sales metrics, Codex only reads sales.md. Similarly, for skills supporting multiple frameworks or variants, organize by variant: ` cloud-deploy/ ├── SKILL.md (workflow + provider selection) └── references/ ├── aws.md (AWS deployment patterns) ├── gcp.md (GCP deployment patterns) └── azure.md (Azure deployment patterns) ` When the user chooses AWS, Codex only reads aws.md. Pattern 3: Conditional details Show basic content, link to advanced content: `markdown

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
