AI SummaryA meta-guide that helps users create or update specialized skills to extend Codex's capabilities with domain-specific knowledge and workflows. Developers and AI agents building custom extensions benefit from this structured approach to skill development.
Install
Copy this and paste it into Claude Code, Cursor, or any AI assistant:
I want to install the "skill-creator" skill in my project. Please run this command in my terminal: # Install skill into your project (7 files) mkdir -p .claude/skills/skill-creator && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/SKILL.md "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/SKILL.md" && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/LICENSE.txt "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/LICENSE.txt" && mkdir -p .claude/skills/skill-creator/agents && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/agents/openai.yaml "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/agents/openai.yaml" && mkdir -p .claude/skills/skill-creator/references && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/references/openai_yaml.md "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/references/openai_yaml.md" && mkdir -p .claude/skills/skill-creator/scripts && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/scripts/generate_openai_yaml.py "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/scripts/generate_openai_yaml.py" && mkdir -p .claude/skills/skill-creator/scripts && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/scripts/init_skill.py "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/scripts/init_skill.py" && mkdir -p .claude/skills/skill-creator/scripts && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/skill-creator/scripts/quick_validate.py "https://raw.githubusercontent.com/openai/skills/main/skills/.system/skill-creator/scripts/quick_validate.py" Then restart Claude Code (or reload the window in Cursor) so the skill is picked up.
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
