dsh-plugin-local-life

Everyday arithmetic is the kind of thing that looks trivial but quietly eats your day: dividing a monthly income across housing, food, and savings, splitting a dinner bill with tip and rounding, figuring out whether the per-kilo or per-100-gram label is the better deal, working out what a threshold coupon actually saves, or converting between jin, li, chi, and miles. dsh-plugin-local-life collects all of these high-frequency calculations into one structured tool so your DSH agent returns a verified result instead of asking you to grab a calculator.

The plugin covers eight core capabilities: generating a monthly budget plan from income and category ratios with a leftover figure; splitting a bill equally or by weights with optional tip and rounding; unit-price comparison (per kg, per 100 g, etc.); percent-off and amount-off discount math with threshold support; unit conversion across four dimensions — weight, length, volume, and temperature; scenario-based trip checklists for city, airport, outdoor, and self-drive outings; an expense-ledger summary by category and month; and full loan amortization schedules under both equal-payment and equal-principal schemes.

Under the hood, all arithmetic lives in a single pure-logic module with zero framework imports, no filesystem access, and no side effects, so every call is deterministic and unit-tested in isolation. A thin wiring layer registers the tool host-wide and can optionally inject a prompt-guidance section that nudges the agent to decompose a financial question into the right sub-calculations. It is built for young professionals setting their first real budget, home cooks comparing grocery unit prices and coupon thresholds, buyers weighing loan offers, and Chinese speakers who think in jin, li, and chi rather than kilograms and kilometres. If your assistant should not just chat but produce a correct bill split, a complete packing list, and a month-by-month repayment table, this plugin closes the gap.
