Overview

[TODO: 1-2 sentences explaining what this skill enables]

Structuring This Skill

[TODO: Choose the structure that best fits this skill's purpose. Common patterns:

1. Workflow-Based (best for sequential processes)

• Works well when there are clear step-by-step procedures
• Example: DOCX skill with "Workflow Decision Tree" -> "Reading" -> "Creating" -> "Editing"
• Structure: ## Overview -> ## Workflow Decision Tree -> ## Step 1 -> ## Step 2...

2. Task-Based (best for tool collections)

• Works well when the skill offers different operations/capabilities
• Example: PDF skill with "Quick Start" -> "Merge PDFs" -> "Split PDFs" -> "Extract Text"
• Structure: ## Overview -> ## Quick Start -> ## Task Category 1 -> ## Task Category 2...

3. Reference/Guidelines (best for standards or specifications)

• Works well for brand guidelines, coding standards, or requirements
• Example: Brand styling with "Brand Guidelines" -> "Colors" -> "Typography" -> "Features"
• Structure: ## Overview -> ## Guidelines -> ## Specifications -> ## Usage...

4. Capabilities-Based (best for integrated systems)

• Works well when the skill provides multiple interrelated features
• Example: Product Management with "Core Capabilities" -> numbered capability list
• Structure: ## Overview -> ## Core Capabilities -> ### 1. Feature -> ### 2. Feature...

Patterns can be mixed and matched as needed. Most skills combine patterns (e.g., start with task-based, add workflow for complex operations).

Delete this entire "Structuring This Skill" section when done - it's just guidance.]

[TODO: Replace with the first main section based on chosen structure]

[TODO: Add content here. See examples in existing skills:

• Code samples for technical skills
• Decision trees for complex workflows
• Concrete examples with realistic user requests
• References to scripts/templates/references as needed]

Resources (optional)

Create only the resource directories this skill actually needs. Delete this section if no resources are required.

scripts/

Executable code (Python/Bash/etc.) that can be run directly to perform specific operations.

Examples from other skills:

• PDF skill: fill_fillable_fields.py, extract_form_field_info.py - utilities for PDF manipulation
• DOCX skill: document.py, utilities.py - Python modules for document processing

Appropriate for: Python scripts, shell scripts, or any executable code that performs automation, data processing, or specific operations.

Note: Scripts may be executed without loading into context, but can still be read by Codex for patching or environment adjustments.

references/

Documentation and reference material intended to be loaded into context to inform Codex's process and thinking.

Examples from other skills:

• Product management: communication.md, context_building.md - detailed workflow guides
• BigQuery: API reference documentation and query examples
• Finance: Schema documentation, company policies

Appropriate for: In-depth documentation, API references, database schemas, comprehensive guides, or any detailed information that Codex should reference while working.

assets/

Files not intended to be loaded into context, but rather used within the output Codex produces.

Examples from other skills:

• Brand styling: PowerPoint template files (.pptx), logo files
• Frontend builder: HTML/React boilerplate project directories
• Typography: Font files (.ttf, .woff2)

Appropriate for: Templates, boilerplate code, document templates, images, icons, fonts, or any files meant to be copied or used in the final output.

Example real reference docs from other skills:

When Reference Docs Are Useful

Reference docs are ideal for:

• Comprehensive API documentation
• Detailed workflow guides
• Complex multi-step processes
• Information too lengthy for main SKILL.md
• Content that's only needed for specific use cases

Structure Suggestions

API Reference Example

• Overview
• Authentication
• Endpoints with examples
• Error codes
• Rate limits

Workflow Guide Example

• Prerequisites
• Step-by-step instructions
• Common patterns
• Troubleshooting
• Best practices """

Example asset files from other skills:

• Brand guidelines: logo.png, slides_template.pptx
• Frontend builder: hello-world/ directory with HTML/React boilerplate
• Typography: custom-font.ttf, font-family.woff2
• Data: sample_data.csv, test_dataset.json

Common Asset Types

• Templates: .pptx, .docx, boilerplate directories
• Images: .png, .jpg, .svg, .gif
• Fonts: .ttf, .otf, .woff, .woff2
• Boilerplate code: Project directories, starter files
• Icons: .ico, .svg
