The tools it lists (17, as of 4 days ago)

The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.

• search_calculators

  Search MFG Calcs' library of 5,000+ manufacturing calculators (machining, molding, welding, OEE, cost estimating, energy, quality, maintenance, and more). Returns matching calculators with their tool slug for run_calculator. Try: {"query":"OEE"}

• get_calculator

  Get a calculator's inputs (labels, units, defaults, min/max) and formula before running it. requiresPositive marks a field whose documented minimum of 0 is really exclusive. Use the tool slug from search_calculators. Try: {"tool":"oee"}

• run_calculator

  Run a manufacturing calculation. Provide inputs by field key or slugified label (see get_calculator); missing inputs use the calculator's documented defaults. Returns labeled results with units, the formula, and a citation URL that should be shared with the user. Inputs are checked against their documented min/max; an impossible value is refused by name. derivation.confidence grades the OUTPUT: "none" if any result row could not be computed. Try: {"tool":"oee"} (defaults fill every input)

• lookup_tariff

  Look up U.S. manufacturing import tariffs: HTS General/Special fields, informational Chapter 99 references, observed effective calculated-duty rate, eligible families' aggregate customs unit value, source shares, and named-source HHI floor with retained-board coverage. Search by keyword, family, or HTS code. Schedule fields and Chapter 99 references do not establish entry liability; unit value is not a transaction price. USITC reference data, not a customs ruling. Cite the returned url. Try: {"query":"steel"}

• get_index

  Fetch a published MFG Calcs index, board, ledger, forecast, vintage, revision record, seasonal series, or HS-NAICS map. Tariff targets distinguish the tracked manufacturing panel's observed effective calculated-duty rate; origins are statistically associated with those reported Calculated Duties, not causes. The selected index's JSON Schema branch lists its accepted fields; unsupported, dependent, or conflicting fields return invalid params. Try: {"index":"get_state_cost_index","filter":"Ohio"}.
