dsh-group-buy

Group buying and split purchases are everyday scenarios, yet the moment headcount, unit price, or discount shifts, manual cost-sharing tends to produce errors and endless back-and-forth in group chats. dsh-group-buy turns that into a single parameterized call: supply key figures such as participants, unit price, and discount, and the plugin computes every line item precisely, returning a structured, detailed breakdown.

Its core strengths are lightness and determinism. Built entirely in Node with zero network dependencies, all calculations run locally in one pass, producing reproducible and trustworthy results. The plugin registers a tool called group_buy that you invoke within a session to get the full price decomposition — total, per-person share, post-discount amount, and more — at a glance.

It is well suited to developers and product folks who regularly join group buys, need to verify shared costs on the fly, or want a clean number to drop into a group chat, cutting down the friction of explaining the math over and over.
