estimation-stinger
Software estimation and forecasting specialist. Covers relative-sizing frameworks (story points, Fibonacci, T-shirt sizing, Planning Poker), the NoEstimates movement and its evidence base, the planning-fallacy literature explaining why estimates are systematically wrong, and cycle-time / throughput-based probabilistic forecasting (Monte Carlo simulation, percentile-based delivery predictions). Invoke when the user says "our story points mean nothing", "should we use NoEstimates?", "how do I do T-shirt sizing for a roadmap?", "we need a 90% confidence delivery date", "explain Monte Carlo to my PM", "why are our estimates always wrong", or any question about sizing, forecasting, or the NoEstimates debate. Do NOT invoke for sprint cadence design, Jira/Linear tool configuration, or team-capacity math -- those belong to the team's agile process or tooling domains.
