These are functions that don’t belong to any specific group. They let you evaluate conditions, mark conversation goals as complete, and extract data from user input using regex.

## [`evaluateRule`](https://docs.cognigy.com/ai/for-developers/function-reference/other/evaluateRule)

**Syntax** `evaluateRule(rule)` Evaluates a condition based on a rule configuration that follows the `left`, `operator`, `right` pattern. This function works similarly to the If Node.

## [`completeGoal`](https://docs.cognigy.com/ai/for-developers/function-reference/other/completeGoal)

**Syntax** `completeGoal(goal)` Marks a goal as `completed` for the conversation.

## [`setRegexSlot`](https://docs.cognigy.com/ai/for-developers/function-reference/other/setRegexSlot)

**Syntax** `setRegexSlot(params)` Extracts Slots from user inputs using a regular expression and writes them to `input.slots`. This function is used by the [Regex Slot Filler](https://docs.cognigy.com/ai/agents/develop/node-reference/ai/regex-slot-filler) Node.
