SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Skill creation guidance helps you define clear, efficient, reusable skill folders so Codex can discover and apply them reliably.

Core Features & Use Cases

  • Skill modularity guidance: Explains how skills are structured into a required SKILL.md plus optional resources (scripts, references, assets).
  • Metadata-first design: Instructs how to write frontmatter (name and description) so discovery works correctly and efficiently.
  • Practical workflow writing: Provides rules for concise instruction bodies, progressive disclosure, and when to use bundled resources.
  • Validation and iteration: Recommends validating the skill layout and forward-testing complex behaviors.

Quick Start

Use the skill-creator guidance to draft a new SKILL.md frontmatter with a precise name and description, then add an instruction body and any needed scripts, references, or assets.

Frequently Asked Questions about skill-creator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a new Codex Skill using YAML frontmatter?

To create a Codex Skill, you draft a SKILL.md file containing YAML frontmatter with valid name and description fields, then add a concise Markdown instruction body with optional scripts, references, or assets.

What is progressive disclosure when writing agent instructions?

Progressive disclosure is a practice for writing agent instructions that keeps operational details concise and layered, exposing complex behaviors only when needed to maintain deterministic skill execution.

How do I structure modular workflows for agent capabilities?

You structure modular workflows by creating a skill folder with a required SKILL.md file for metadata and instructions, then adding optional resources like deterministic scripts, reference material, and reusable assets.

What's the best way to validate a Codex Skill layout before deployment?

The best way to validate a Codex Skill layout is to review the YAML frontmatter for correct name and description fields, check the instruction body for conciseness, and forward-test complex behaviors against expected agent outcomes.

Do I need bundled scripts to extend agent capabilities with a skill folder?

You do not need bundled scripts to extend agent capabilities; a valid SKILL.md with safe operational instructions suffices, though adding deterministic scripts and reusable assets enhances complex workflows.

Why does my Codex Skill discovery fail despite having a SKILL.md file?

Codex Skill discovery fails if the SKILL.md YAML frontmatter lacks valid name and description fields, or if the instruction body violates progressive disclosure and validation practices required for reliable agent parsing.
