### Step 5: Packaging a Skill
|
||||
### Step 5: Validate the Skill
|
||||
|
||||
Once development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
|
||||
Once development of the skill is complete, validate the skill folder to catch basic issues early:
|
||||
|
||||
```bash
|
||||
scripts/package_skill.py <path/to/skill-folder>
|
||||
scripts/quick_validate.py <path/to/skill-folder>
|
||||
```
|
||||
|
||||
Optional output directory specification:
|
||||
|
||||
```bash
|
||||
scripts/package_skill.py <path/to/skill-folder> ./dist
|
||||
```
|
||||
|
||||
The packaging script will:
|
||||
|
||||
1. **Validate** the skill automatically, checking:
|
||||
|
||||
- YAML frontmatter format and required fields
|
||||
- Skill naming conventions and directory structure
|
||||
- Description completeness and quality
|
||||
- File organization and resource references
|
||||
|
||||
2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.
|
||||
|
||||
If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
|

The validation script checks YAML frontmatter format, required fields, and naming rules. If validation fails, fix the reported issues and run the command again.
