Advanced Skill Creator

Advanced patterns for creating complex, multi-step skills with error handling and state management.

When to Use

• Multi-step workflows with dependencies
• Skills requiring state persistence
• Complex error handling scenarios
• Integration with external APIs

Patterns

State Machine Pattern

# STATE.yaml
step: 2
status: in_progress
completed:
  - step_1_auth
remaining:
  - step_2_fetch
  - step_3_process
errors: []

Error Recovery

# Retry with backoff
for attempt in range(3):
    try:
        result = api.call()
        break
    except APIError as e:
        if attempt == 2:
            raise
        time.sleep(2 ** attempt)

Best Practices

1. Define clear entry/exit points
2. Validate inputs before processing
3. Log all state transitions
4. Provide rollback on failure
