Helps create, update, or improve agent skills. Useful for ensuring skill descriptions are clear and accurate.
What it does
This tool helps you create and improve 'skills' (sets of instructions) for AI agents. It guides you on how to organize content, name things correctly, and ensure the AI understands and follows instructions.
When to use it
- ✓When creating a new instruction for the AI.
- ✓When trying to make the AI follow rules better.
- ✓When organizing or renaming existing instructions.
Example of what to ask your AI
“How can I create a simple instruction for the AI to help it write emails?”

How to use
The easiest way: copy the message below and paste it into Claude, ChatGPT, Cursor or any AI. It reads the skill and follows the instructions.

Ready-to-paste message
How it works
The tool uses a decision tree to guide you. You select whether you want to create something new or improve something existing, then choose the instruction type and the standards to follow.
Installation
Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.
In the terminal (Claude Code, Codex, Cursor), in your project folder:

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?
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
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)
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
- Identify goal → Use decision tree above
- Select template → From
references/templates/ - Apply CSO → Optimize description for discovery
- Add anti-rationalization → For discipline skills
- Test → RED-GREEN-REFACTOR cycle
Quick Example
---
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.

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