Produces a conditional collection plan and prioritized missing measurements; does not book transport or arrange collection.

Compare keeping, repairing, or upgrading an owned item with a new or pre-owned replacement. Use when deciding whether an existing item still meets the owner's needs or whether a repair is worthwhile. Produces a conditional recommendation grounded in costs, suitability, and uncertainty; does not diagnose faults or arrange repairs or purchases.

Assemble a complete setup from new or pre-owned items for an outcome such as recording a podcast, starting photography, or equipping a workshop. Use when several components must work together within one budget, including gear the buyer already owns. Produces a compatible bill of materials, alternatives, and acquisition dependencies; does not purchase or reserve items.
