## 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.
|
||||

||||

||||

- bigquery/references/ - API references and query examples
|

|

## 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
|

- Rate limits

### Workflow Guide Example

|
||||
- Common patterns
|
||||
- Troubleshooting

||||
- Best practices
