What problem does it solve? Freelancers and engineers who use AI coding agents struggle to turn metered token spend and shipped work into billing paperwork. This Skill converts the waybill ledger's receipts into a client invoice pack or a personal expense receipt without inventing hours or prices. ## Core Features & Use Cases - Client invoice pack: Renders one line item per shipped work entry with recorded hours, PR/deploy links, and disclosed AI assistance costs, plus totals, an AI disclosure statement, and an optional verification offer. - Personal expense receipt: Produces metered AI costs for a period with by-model breakdown and CSV export ready for finance tools, labeled as list-price equivalents rather than a provider invoice. - Facts-only guarantee: Never presents counterfactual estimates as billable hours, never sets rates or prices, and marks missing data with "—" instead of guessing. - Use Case: A freelancer says "invoice my client for last month" and receives an itemized invoice of shipped work with recorded hours and disclosed AI costs, ready to pair with their own rate. ## Quick Start Ask the assistant to prepare your invoice for last month from your waybill ledger.
