Overview
This skill helps diagnose and fix a critical error pattern where I/O operations (HTTP calls, database queries, file operations) are performed directly in workflow functions instead of in steps. This violates Temporal's determinism requirements.
When to Use This Skill
You're seeing:
- Workflow hangs indefinitely
- Undefined or empty responses
- "workflow must be deterministic" errors
- Network operations failing silently
- Timeouts without clear cause
