Compute an out-the-door (OTD) estimate or reverse a target OTD into a sales-price ceiling using verified, explicitly supported state rules. Triggers include "compute OTD", "OTD math", "what's my OTD", "reverse OTD to sale price", "算 OTD", "算总价", "calcula el precio final del carro", and "calcula el precio total con impuestos y cargos".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OTD Calculator Use the installed orchestrator's `../orchestrator/scripts/otd_calculator.py`. It resolves the real repository path through Windows junctions. State fees and tax rules come from `data/state_fees.json`; each reviewed field has its own source and effective scope. The result is an **estimate** with explicit fee inputs. A successful calculation does not confirm a dealer offer or the legality/completeness of every fee. Ordinary in-state resident dealer purchases of passenger ICE vehicles are the supported transaction class. Check the current profile table below; an unsupported profile must produce an actionable refusal. ## Required inputs and gate 1. Confirm the state, transaction date, in-state dealer/resident context, passenger ICE vehicle, and whether this is an ordinary purchase. Lease, private-party, EV, commercial, exemption, rebate and new-resident branches need their own official calculation. …

How to install
mdr add daizedong/buy-me-a-car/otd-calculator@sha256:115fb9c3bdca2623The line at the top of this page pins the label git:20261014.37793b4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
