Calling Convention

Call this skill with a structured request:

{
  "name": "my-skill",

  "instructions": "## Overview\n\nDetailed instructions in markdown...",
  "scripts": [
    {"name": "main.py", "content": "#!/usr/bin/env python3\n...", "language": "python"}
  ],
  "references": [
    {"name": "api-docs.md", "content": "# API Reference\n..."}
  ]
}

Workflow

1. Validate parameters - Check skill_name format, required fields
2. Create directory structure - skill_name/ with appropriate subdirectories
3. Generate SKILL.md - Write frontmatter + instructions
4. Create resources - Write scripts, references, assets if provided
5. Validate - Run skill validation (optional, default: on)
6. Package - Generate .skill file (optional, default: on)
7. Return result - Report created files and location

Output

Returns a result object:

{
  "success": true,
  "skill_path": "~/.openclaw/workspace/skills/my-skill",
  "skill_file": "~/.openclaw/workspace/skills/my-skill.skill",
  "files_created": ["SKILL.md", "scripts/main.py"]
}

Quick Example

A calling skill might invoke this with:

Create a skill named "pdf-watermarker" that:
- Description: "Add watermarks to PDF files. Use when processing PDFs for branding or security."
- Instructions: Basic watermarking workflow with pdfplumber
- Scripts: A watermark.py script using PyPDF2

The skill factory handles all file creation, validation, and packaging.
