# ST-MRD-004 - Unreachable Activities

> **Rule ID**: `ST-MRD-004`

**Rule ID**: `ST-MRD-004`

**Scope**: Workflow

## Description

This rule checks whether activities in the file or project have connecting nodes in the flowchart or are not connected to the Start node.

## Recommendation

Workflows should only have the necessary activities for execution, and activities that are commented out or that are not connected to any node in a flowchart should be removed. If there is a need to keep commented activities, add annotations to describe the reason. Consider removing unreachable activities.
