Design Philosophy

These skills teach workflows while pointing to live documentation for details that change frequently:

• Step-by-step instructions for common tasks (not just API reference)
• Real user scenario examples with trigger → actions → result
• Error handling and troubleshooting for common failure modes
• references/ directories for detailed lookup tables loaded on demand
• Agents fetch the latest docs, SDK READMEs, and API specs at runtime
• The canonical source of truth remains docs.stackone.com

Documentation Index

StackOne publishes a machine-readable documentation index at docs.stackone.com/llms.txt — agents can fetch this to discover all available documentation pages.
