Software tool passes all tests but never runs due to missing scheduler

A software development tool, MCP, was found to have a critical acceptance gap despite passing all 33 of its tests. The tool was designed to scan public sources for relevant conversations but was never actually executed due to a missing scheduler.

To prevent this, a new guard was implemented that checks if daily-running scripts are present in a scheduled workflow, ensuring that tools are not only functional but also operational. AI
