Writing Skills (Excellence)

Dispatcher for skill creation excellence. Use the decision tree below to find the right template and standards.

⚡ Quick Decision Tree

What do you need to do?

  1. Create a NEW skill:

    • Is it simple (single file, <200 lines)? → Tier 1 Architecture
    • Is it complex (multi-concept, 200-1000 lines)? → Tier 2 Architecture
    • Is it a massive platform (10+ products, AWS, Convex)? → Tier 3 Architecture
  2. Improve an EXISTING skill:

    • Fix "it's too long" -> Modularize (Tier 3)
    • Fix "AI ignores rules" -> Anti-Rationalization
    • Fix "users can't find it" -> CSO (Search Optimization)
  3. Verify Compliance:

    • Check metadata/naming -> Standards
    • Add tests -> Testing Guide

📚 Component Index

Component Purpose
CSO "SEO for LLMs". How to write descriptions that trigger.
Standards File naming, YAML frontmatter, directory structure.
Anti-Rationalization How to write rules that agents won't ignore.
Testing How to ensure your skill actually works.

🛠️ Templates

  • Technique Skill (How-to)
  • Reference Skill (Docs)
  • Discipline Skill (Rules)
  • Pattern Skill (Design Patterns)

When to Use

  • Creating a NEW skill from scratch
  • Improving an EXISTING skill that agents ignore
  • Debugging why a skill isn't being triggered
  • Standardizing skills across a team

How It Works

  1. Identify goal → Use decision tree above
  2. Select template → From references/templates/
  3. Apply CSO → Optimize description for discovery
  4. Add anti-rationalization → For discipline skills
  5. Test → RED-GREEN-REFACTOR cycle

Quick Example

yaml
---
name: my-technique
description: Use when [specific symptom occurs].
metadata:
  category: technique
  triggers: error-text, symptom, tool-name
---

# My Technique

## When to Use
- [Symptom A]
- [Error message]

Common Mistakes

Mistake Fix
Description summarizes workflow Use "Use when..." triggers only
No metadata.triggers Add 3+ keywords
Generic name ("helper") Use gerund (creating-skills)
Long monolithic SKILL.md Split into references/

See gotchas.md for more.

✅ Pre-Deploy Checklist

Before deploying any skill:

  • name field matches directory name exactly
  • SKILL.md filename is ALL CAPS
  • Description starts with "Use when..."
  • metadata.triggers has 3+ keywords
  • Total lines < 500 (use references/ for more)
  • No @ force-loading in cross-references
  • Tested with real scenarios
