Writing Tips

Be Specific

❌ "Use when working with databases" ✅ "Use when optimizing SQL queries for PostgreSQL 14+ production databases"

Be Actionable

❌ "Think about security" ✅ "Run OWASP ZAP scan and review all HIGH severity findings"

Be Structured

Use consistent heading levels:

• ## for major sections
• ### for subsections
• #### for detailed breakdowns

Use Visual Indicators

• ✅ for good practices
• ❌ for anti-patterns
• 🔍 for investigation steps
• ⚠️ for warnings
• 💡 for tips

Include Context

Don't just list what to do—explain why:

## Instead of:
- Use connection pooling

## Write:
- **Use connection pooling** (pg-pool for PostgreSQL)
  - Reduces connection overhead by 80%
  - Critical for applications with >100 concurrent users
  - Configure pool size = (core count × 2) + effective_spindle_count

Skill Maintenance

When to Update

• New version of core technology released
• Better practices emerge in the field
• User feedback reveals gaps
• Related skills are created (cross-reference)

Version Control

Consider adding to frontmatter:

---
name: skill-name
description: One-line description
---

Skill Integration

Cross-References

Link to related skills:

## Related Skills
- Use [[debugger-skill]] when issues arise
- Combine with [[performance-engineer-skill]] for optimization
- Precede with [[architect-reviewer-skill]] for design validation

Skill Composition

Complex workflows can chain skills:

## Workflow
1. Use [[requirement-analyst]] to gather needs
2. Apply this skill for implementation
3. Use [[code-reviewer]] for quality assurance
4. Use [[deployment-engineer]] to ship

Examples

Example 1: Creating a Python Pro Skill

Context: Need a skill for advanced Python development

1. Add workflow: Design API → Type models → Implement routes → Test
2. Include examples: FastAPI route with full type annotations

Result: A focused, actionable skill for modern Python development

Example 2: Creating a Git Workflow Skill

Context: Need to codify team's git branching strategy

Process:

1. Define scope: Git workflow for feature development
2. Identify triggers: "create branch", "make PR", "git workflow"
