progressive-estimation
About
This skill provides statistical task estimation using PERT formulas and calibration feedback, specifically designed for AI-assisted or hybrid human+agent development work. It adapts velocity models for different team modes (human-only, hybrid, or agent-first) to improve sprint planning and backlog sizing. Developers use it to replace gut-feel estimates with research-backed confidence bands for more accurate project forecasting.
