Best Practices

Content Quality

✅ DO:

Write clear, detailed SOUL definitions (500+ words)
Include specific examples and scenarios
Define clear boundaries (ALWAYS/NEVER rules)
Test your SOUL thoroughly before publishing
Use proper markdown formatting
Include relevant expertise areas

❌ DON'T:

Copy existing SOULs without significant modification
Use vague or generic descriptions
Omit important operational boundaries
Publish untested SOULs
Include sensitive/private information
Use misleading names or descriptions

Pricing Strategy

Free ($0): Great for building reputation and getting downloads
Low ($1-10): Specialized but simple SOULs
Medium ($10-50): Complex, domain-specific expertise
High ($50+): Highly specialized, enterprise-grade SOULs

Tags & Discovery

Use 3-5 relevant tags
Mix broad and specific tags (email, gmail-automation)
Research popular tags in your category
Use consistent tag formatting (lowercase, hyphenated)

Version Control

Keep your source SOUL.md in version control (Git)
Document changes in commit messages
Consider semantic versioning in your SOUL name/description
Update your published SOUL when making improvements
