About this plugin
LLMs have a well-known blind spot with finance math: they misremember PMT formulas, lose precision in compound-interest chains, or return a fabricated IRR when the sign-change pattern doesn't cooperate. dsh-finance pulls that arithmetic out of the model's memory and into a set of deterministic tool calls, so the LLM handles intent and parameter assembly while exact math happens downstream.
Use Cases
- Answering 'what is my monthly mortgage payment and total interest over 30 years?' via a single loan_payment call instead of risking arithmetic drift
- Evaluating a multi-period project's NPV, IRR, and payback period with cashflow_analysis so the IRR bisection is exact and multi-sign-change cases are flagged honestly
- Checking whether a retirement balance survives a fixed monthly withdrawal for a given horizon, or computing the sustainable payout with retirement_plan
Best For
- Developers building finance Q&A or research agents on DeepSeek Harness
- Teams whose chatbot must return exact loan, annuity, or cash-flow figures without trusting the model's mental math
- Integrators who need a zero-dependency, fully deterministic finance module that is auditable and safe to run anywhere
