Overview

Enables early pipeline exit on success. Used for idempotency and guard clauses.

On success: marks result with shortcut flag, causing Sequence to exit immediately. On failure: returns empty success, allowing pipeline to continue.

Examples:

Idempotent post creation

sequence(
  shortcut(find_existing_post),  # Found? Exit with existing post
  validate_params,                # Not found? Continue creation
  create_post
)

Guard clause

sequence(
  shortcut(check_already_subscribed),  # Already subscribed? Done
  validate_subscription,
  create_subscription
)
