What problem does it solve? Estimating software project cost and effort is error-prone when done from gut feeling, leading to underpriced quotes and blown schedules. This Skill runs a disciplined SOP that grounds every estimate in historical actuals, market research, and a structured WBS before producing a client-ready quotation. ## Core Features & Use Cases - Historical Calibration: Queries the rsun-citation MCP for past project metrics (variance percentages, similar cases, reusable modules) and adjusts work hours and buffer multipliers accordingly. - WBS & Cost Calculation: Breaks requirements into modules and work packages sized S/M/L/XL, computes person-months, internal cost, margin multiplier, tax, and a 30/40/40 payment schedule. - Deliverable Generation: Creates a Google Sheets estimate from a Drive template and outputs a copy-paste-ready pricing summary. - Use Case: A client asks for a CRM system quote. The Skill analyzes requirements, pulls variance stats showing past CRM projects ran 18% over, applies the correction, builds the WBS, and delivers an itemized quotation sheet. ## Quick Start Ask the assistant to estimate and quote a described project, for example: help me estimate and produce a quotation for a booking system with user accounts and payment integration.
