Marketplace create-skill
Guide for creating new skills in Kai's personal AI infrastructure. Use when user wants to create, update, or structure a new skill that extends capabilities with specialized knowledge, workflows, or tool integrations. Follows both Anthropic skill standards and PAI-specific patterns.

Create Skill - Skill Creation Framework
When to Activate This Skill
- "Create a new skill for X"
- "Build a skill that does Y"
- "Add a skill for Z"
- "Update/improve existing skill"
- "Structure a skill properly"
- User wants to extend Kai's capabilities
Core Skill Creation Workflow
Step 1: Understand the Purpose
Ask these questions:
- What does this skill do? (Clear, specific purpose)
- When should it activate? (Trigger conditions)
- What tools/commands does it use? (Dependencies)
- Is it simple or complex? (Determines structure)
Step 2: Choose Skill Type
Simple Skill (SKILL.md only):
- Single focused capability
- Minimal dependencies
- Quick reference suffices
- Examples: fabric-patterns, youtube-extraction
Complex Skill (SKILL.md + CLAUDE.md + supporting files):
- Multi-step workflows
- Extensive context needed
- Multiple sub-components
- Examples: development, website, consulting
Step 3: Create Directory Structure
# Simple skill ${PAI_DIR}/skills/[skill-name]/ └── SKILL.md # Complex skill ${PAI_DIR}/skills/[skill-name]/ ├── SKILL.md # Quick reference ├── CLAUDE.md # Full context └── [subdirectories]/ # Supporting resources
Step 4: Write SKILL.md (Required)
Use this structure:
--- name: skill-name description: Clear description of what skill does and when to use it. Should match activation triggers. --- # Skill Name ## When to Activate This Skill - Trigger condition 1 - Trigger condition 2 - User phrase examples ## [Main Content Sections] - Core workflow - Key commands - Examples - Best practices ## Supplementary Resources For detailed context: `read ${PAI_DIR}/skills/[skill-name]/CLAUDE.md`
Step 5: Write CLAUDE.md (If Complex)
Include:
- Comprehensive methodology
- Detailed workflows
- Component documentation
- Advanced usage patterns
- Integration instructions
- Troubleshooting guides
Step 6: Add to Global Context
Update
${PAI_DIR}/global/KAI.md available_skills section to include the new skill so it shows up in the system prompt.
Step 7: Test the Skill
- Trigger it with natural language
- Verify it loads correctly
- Check all references work
- Validate against examples
Skill Naming Conventions
- Lowercase with hyphens:
,create-skillweb-scraping - Descriptive, not generic:
notfabric-patternstext-processing - Action or domain focused:
,ai-image-generationchrome-devtools
Description Best Practices
Your description should:
- Clearly state what the skill does
- Include trigger phrases (e.g., "USE WHEN user says...")
- Mention key tools/methods used
- Be concise but complete (1-3 sentences)
Good examples:
- "Multi-source comprehensive research using perplexity-researcher, claude-researcher, and gemini-researcher agents. Launches up to 10 parallel research agents for fast results. USE WHEN user says 'do research', 'research X', 'find information about'..."
- "Chrome DevTools MCP for web application debugging, visual testing, and browser automation. The ONLY acceptable way to debug web apps - NEVER use curl, fetch, or wget."

Key Principles
- Progressive disclosure: SKILL.md = quick reference, CLAUDE.md = deep dive
- Clear activation triggers: User should know when skill applies
- Executable instructions: Imperative/infinitive form (verb-first)
- Context inheritance: Skills inherit global context automatically
- No duplication: Reference global context, don't duplicate it
- Self-contained: Skill should work independently
- Discoverable: Description enables Kai to match user intent
