Each tool occupies a distinct stage of the workflow: choose_program selects a program, get_limits_and_costs supplies the reference data, and size_loan performs the calculation. An agent can easily tell which one to invoke based on whether it needs a decision, data, or a number.
All three names are snake_case and follow a verb_noun pattern (choose_program, get_limits_and_costs, size_loan). The convention is predictable and readable throughout.
Three tools is on the low end but each covers a clearly separate function in a narrow domain (program chooser, limits reference, loan sizer). The set is well-scoped rather than padded, though it leaves little room for auxiliary operations.
The surface covers the core workflow end to end: pick a program, look up limits/costs, and size a 223(f) or 221(d)(4) loan. Minor gaps exist—sizing is not offered for 223(a)(7) or 241(a), which choose_program can return, and there is no way to refresh or compare scenarios.
