Architectural Overview
"This module is grounded in ai engineering patterns and exposes 1 core capabilities across 1 execution phases."
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.
✅ Pre-Deploy Checklist
Before deploying any skill:
-
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

Examples
Create a Tier 1 skill:
mkdir -p ~/.config/opencode/skills/my-technique
touch ~/.config/opencode/skills/my-technique/SKILL.md
Create a Tier 2 skill:
mkdir -p ~/.config/opencode/skills/my-skill/references/core
touch ~/.config/opencode/skills/my-skill/{SKILL.md,gotchas.md}
touch ~/.config/opencode/skills/my-skill/references/core/README.md
