bookfinder-general

Turn a book in your bookfinder-general library into a reusable skill: a study-skill (frameworks, glossary, on-demand chapters) for any book, or a methodology-skill (a runnable calculator grounded in the book's own numbers) for books with a quantitative model. Use when you want to operationalize a book — not just summarize it — e.g. turn a logistics or formation treatise into an advisor that computes.

Logistic and movement advisor built from Donald Engels, Alexander the Great and the Logistics of the Macedonian Army (1978). Computes daily/march grain-water-forage requirements, pack-animal counts, operational range from a depot, and desert-crossing feasibility for an ancient army; explains Engels's supply constraints. Use when designing or adjudicating army supply/movement (wargame rules, campaign planning, what-if marches) or when reasoning about pre-modern logistics.

Formation-geometry advisor built from Taylor, The Macedonian Phalanx (2020). Computes phalanx frontage, depth, men-to-hold-a-line, sarissa-hedge projection (how many ranks' points reach the enemy), unit breakdown (file -> syntagma -> phalanx), and frontal density vs a Roman line; explains how the phalanx fought and its limits. Use when designing or adjudicating ancient pike/spear formations (wargame rules, scenario setup, what-if deployments) or reasoning about phalanx tactics.
