.. _auto_string_is_equal:

*STRING EQUALS WITH*
====================

Compares two scalar strings for exact equality and returns a boolean result. Use this worker in workflow branching logic wherever you need to check whether a string value matches an expected target string.

When to use
-----------

Classification: **process**.

Tagged: ``boolean``, ``branching``, ``comparison``, ``equality``, ``process``, ``scalar``, ``string``.

Inputs

     - Default
     - Required
     - Description
   * - Haystack
     - haystack
     - scalar
     - —
     - ✓
     - The source string to be evaluated (e.g. a variable or extracted text value); compared against the needle for exact equality.
   * - Needle
     - needle
     - scalar
     - —
     - ✓
     - The target string to match against the haystack; provide the exact literal or variable value you expect the haystack to equal.

   * - string_is_equal_output_1
     - string_is_equal_output_1
     - scalar
     - Boolean scalar result — true if haystack exactly equals needle, false otherwise; use this to drive conditional branching in the workflow.
