This skill provides guidance for creating effective skills for Codex CLI environments.
Compatibility note: Any plugin-oriented examples in this document are legacy references. Prefer the Codex skill locations described below.
To create high-quality skills, follow this Hybrid Workflow:
scripts/, references/, or just SKILL.md.skill-createUse this skill as the refinement stage after $skill-create generates drafts.
Pipeline:
$skill-create$skill-development$skill-quality-analyzer for structure and trigger quality$skill-tester for behavioral validationSkills are modular, self-contained packages 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.
Every skill consists of a required SKILL.md file and optional bundled resources:
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)

└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
Metadata Quality: The name and description in YAML frontmatter determine when Codex will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").
scripts/)Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
scripts/rotate_pdf.py for PDF rotation tasksreferences/)Documentation and reference material intended to be loaded as needed into context to inform Codex's process and thinking.
references/finance.md for financial schemas, references/mnda.md for company NDA template, references/policies.md for company policies, references/api_docs.md for API specificationsassets/)Files not intended to be loaded into context, but rather used within the output Codex produces.
assets/logo.png for brand assets, assets/slides.pptx for PowerPoint templates, assets/frontend-template/ for HTML/React boilerplate, assets/font.ttf for typographySkills use a three-level loading system to manage context efficiently:
*Unlimited because scripts can be executed without reading into context window.
To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.
Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
To turn concrete examples into an effective skill, analyze each example by:
Example: When building a pdf-editor skill to handle queries like "Help me rotate this PDF," the analysis shows:
scripts/rotate_pdf.py script would be helpful to store in the skillExample: When designing a frontend-webapp-builder skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
assets/hello-world/ template containing the boilerplate HTML/React project files would be helpful to store in the skillExample: When building a big-query skill to handle queries like "How many users have logged in today?" the analysis shows:
references/schema.md file documenting the table schemas would be helpful to store in the skillFor Codex CLI skills: When building a hooks-related skill, the analysis shows:
scripts/validate-hook-schema.sh and scripts/test-hook.sh utilities would be helpfulreferences/patterns.md for detailed hook patterns to avoid bloating SKILL.mdTo establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
For Codex CLI, create the skill directory structure:
mkdir -p skill-name/{references,examples,scripts}
touch skill-name/SKILL.md
Note: Unlike the generic skill-creator which uses init_skill.py, Codex CLI skills are created directly in a skill directory and then placed under ~/.codex/skills/, <repo>/.codex/skills/, or <repo>/.agents/skills/.
When editing the (newly-created or existing) skill, remember that the skill is being created for another instance of Codex to use. Focus on including information that would be beneficial and non-obvious to Codex. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Codex instance execute these tasks more effectively.
To begin implementation, start with the reusable resources identified above: scripts/, references/, and assets/ files. Note that this step may require user input. For example, when implementing a brand-guidelines skill, the user may need to provide brand assets or templates to store in assets/, or documentation to store in references/.
Also, delete any example files and directories not needed for the skill. Create only the directories you actually need (references/, examples/, scripts/).
Writing Style: Write the entire skill using imperative/infinitive form (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.
Description (Frontmatter): Use third-person format with specific trigger phrases:
---
name: Skill Name
description: This skill should be used when the user asks to "specific phrase 1", "specific phrase 2", "specific phrase 3". Include exact phrases users would say that should trigger this skill. Be concrete and specific.
version: 0.1.0
---
Good description examples:
description: This skill should be used when the user asks to "create a validation rule", "define a skill trigger", "validate tool use instructions", or "design prompt guardrails".
Bad description examples:
description: Use this skill when working with hooks. # Wrong person, vague
description: Load when user needs hook help. # Not third person
description: Provides hook guidance. # No trigger phrases
To complete SKILL.md body, answer the following questions:
Keep SKILL.md lean: Target 1,500-2,000 words for the body. Move detailed content to references/:

For Codex CLI skills, validation is different from generic skills:
~/.codex/skills/skill-name/, <repo>/.codex/skills/skill-name/, or <repo>/.agents/skills/skill-name/Use the skill-reviewer agent:
Ask: "Review my skill and check if it follows best practices"
The skill-reviewer agent will check description quality, content organization, and progressive disclosure.
After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
Iteration workflow:
Common improvements:
Skills for Codex CLI should live in one of these locations:
~/.codex/skills/
└── my-skill/
├── SKILL.md
├── references/
├── examples/
└── scripts/
<repo>/.agent/skills/
└── my-skill/
├── SKILL.md
├── references/
├── examples/
└── scripts/
Codex automatically discovers skills:
skills/ directorySKILL.mdSkills are plain directories. Install globally via ~/.codex/skills/ or keep project-local under .codex/skills/ / .agents/skills/.
Test skills by opening Codex in the target repo and invoking explicit triggers:
# Example explicit invocation
$skill-name <task>
Study existing skill packs as examples of best practices:
hook-development skill:
agent-development skill:
settings-management skill:
Each demonstrates progressive disclosure and strong triggering.
Include (always loaded when skill triggers):
Keep under 3,000 words, ideally 1,500-2,000 words
Move to references/ (loaded as needed):
Each reference file can be large (2,000-5,000+ words)
Working code examples:
Users can copy and adapt these directly
Utility scripts:
Should be executable and documented
Write using verb-first instructions, not second person:
Correct (imperative):
To create a hook, define the event type.
Configure the MCP server with authentication.
Validate settings before use.
Incorrect (second person):
You should create a hook by defining the event type.
You need to configure the MCP server.
You must validate settings before use.
The frontmatter description must use third person:
Correct:
description: This skill should be used when the user asks to "create X", "configure Y"...
Incorrect:
description: Use this skill when you want to create X...
description: Load this skill when user asks...
Focus on what to do, not who should do it:
Correct:
Parse the frontmatter using sed.
Extract fields with grep.
Validate values before use.
Incorrect:
You can parse the frontmatter...
Codex should extract fields...
The user might validate values...
