dsh-breakeven

Before opening a small shop, the question that keeps most owners up at night is simply: how much do I need to sell before I stop losing money? The usual answer is a half-hour battle with a spreadsheet, tweaking assumptions and re-checking formulas. dsh-breakeven collapses that step into a single tool call inside your Agent session, so you get the result immediately without ever opening an external calculator.

The plugin registers a tool called breakeven. You feed it the operating parameters that matter to your scenario such as fixed costs, per-unit margin, and selling price, and it returns the break-even point along with the key figures behind the result. The entire implementation is pure Node.js with zero network calls, which means it runs reliably on an air-gapped host or any environment where outbound traffic is restricted.

It is built for the independent cafe owner, the home baker testing a side hustle, and the corner-shop operator deciding whether a new product is worth the shelf space. It also suits the freelance consultant or startup coach who needs a quick feasibility check during a client call. The goal is not a full financial model; it is a fast, defensible break-even number that tells you whether to dig deeper or walk away.
