About
PROBE Estimation is a specialized skill for Claude Code that brings the rigor of the Personal Software Process (PSP) to agile story sizing. By mapping story points to size categories and utilizing historical proxy data, it calculates statistically grounded effort ranges—including optimistic, likely, and pessimistic forecasts—rather than relying on subjective gut feelings. This skill automates the tracking of actual versus estimated time, enabling teams to continuously improve their velocity and capacity planning accuracy through automated correlation analysis and performance metrics integrated directly into the development workflow.
