Creating New Skills
When to Create a Skill
After completing work, ask yourself:
- •Would this procedure help on similar future tasks?
- •Did I make mistakes that a checklist would prevent?
- •Is this complex enough that future-me might skip steps?
- •Did I learn a pattern worth codifying?
If yes to any → Extract to skill.
Skill Structure Template
markdown
--- name: Clear Descriptive Name when_to_use: Specific trigger conditions that indicate this skill applies --- # Overview Core principle in 1-2 sentences. What's the key insight? # Implementation Checklist - [ ] First step - [ ] Second step - [ ] Third step - [ ] Verify results # Quality Standards Specific criteria for success: - What must be true when done? - What errors must be zero? - What verification proves it works? # Anti-Patterns Common mistakes to avoid: ❌ Bad pattern - why it's wrong ✅ Good pattern - why it's right # Supporting Links to tools, scripts, or reference docs: - Tool documentation: path/to/tool/docs - Related skills: path/to/related/SKILL.md
Testing Process
Before adding a skill to the library:
- •Write the skill following template above
- •Self-test by following it yourself for a similar task
- •Test on subagent (optional but recommended):
- •Dispatch subagent with realistic task
- •Give subagent access to the skill
- •Watch for places subagent might skip steps or misinterpret
- •Strengthen language where compliance is weak
- •Retest until bulletproof
Adding to Library
bash
# Create skill directory and file mkdir -p ~/.config/agent/skills/skills/[category]/[skill-name] vim ~/.config/agent/skills/skills/[category]/[skill-name]/SKILL.md # Test by using it yourself # Commit when satisfied cd ~/.config/agent/skills git add skills/[category]/[skill-name]/SKILL.md git commit -m "Add [skill-name] skill for [purpose]" # Push if you're working from a fork git push origin main
Categories
Organize skills into logical categories:
- •meta/ - Skills about skills (like this one)
- •research/ - Information gathering and verification
- •data-analysis/ - Working with data, spreadsheets, visualization
- •communication/ - Writing, reporting, documentation
- •automation/ - Task automation, scripting, workflows
- •tools/ - Reference docs for specific tools (supporting only)
Skill vs Tool Documentation
Skill: Process-focused, tells you WHAT to do and WHEN
- •"When analyzing data, always verify with multiple sources"
- •"Use formulas instead of hardcoded values"
- •"Test edge cases before declaring complete"
Tool doc: Tool-focused, tells you HOW to use specific technology
- •"pandas.read_excel() loads Excel files"
- •"openpyxl preserves formulas"
- •"WebFetch retrieves web content"
Put tool docs in skills/tools/[tool-name]/ as supporting material. Put processes in skills/[category]/[skill-name]/.
Quality Checklist for New Skills
Before committing a new skill:
- • Has clear
nameandwhen_to_usein frontmatter - • Includes Overview section with core principle
- • Has Implementation checklist with actionable steps
- • Defines Quality Standards or success criteria
- • Includes Anti-Patterns section if relevant
- • Has been self-tested on realistic scenario
- • Language is strong enough to enforce compliance
- • Placed in appropriate category
Self-Improvement Loop
This is the key to the system:
code
Agent encounters task → Uses existing skill (or creates new pattern) → Learns something reusable → Writes new skill → Future agents use it → System gets smarter
Your job is to recognize when patterns are reusable and codify them. The library grows organically as you work.
