Оценка трудозатрат на разработку (PERT, T-shirt, FPA)

project-sizing-guide is a Claude Code skill that assists teams in estimating software project effort using three methodologies: Three-Point Estimation (PERT), T-shirt Sizing, and Function Point Analysis (FPA). It triggers when users ask how long a feature will take, need to break requirements into a Work Breakdown Structure, or require optimistic, most-likely, and pessimistic values with confidence intervals ranging from 68.3% to 99.7%. A bundled `estimate_calculator.py` script lets you compute PERT metrics directly from the command line. Each method follows a defined workflow: T-shirt sizing suits early feasibility and rough budgeting, PERT fits sprint planning, and FPA is recommended for contract bids and large-project RFPs. The skill is designed for product teams, project managers, and anyone involved in effort estimation and project quoting.
