Technical preview
A deterministic node in a LangGraph workflow
This page is for people building LangGraph workflows and other AI graphs. Your graph gathers evidence. A person admits each answer at an interrupt. SMEme evaluates a deployed decision tree over MCP and returns the next question or a report. The model proposes. It does not choose the conclusion.
The ACME withholding example
The example is an opt-in fictional cross-border withholding decision tree. Loading it creates, Deploys, and Lists one tree on the signed-in account and uses one decision-tree slot. It does not replace the two-question sample that a new account receives.
Fictional technical demonstration only. This decision tree and its synthetic case files are provided solely to demonstrate SMEme and LangGraph integration. They are incomplete and are not legal, tax, accounting, compliance, or other professional advice. They must not be used to determine obligations in any real transaction. ACME, Inc., party D, matter numbers, people, records, and transactions are fictional. Any resemblance to real people, organizations, or transactions is coincidental. The example does not claim to encode complete or current tax law. Provenance records where an answer came from; it does not establish that a source is true, authoritative, current, or legally sufficient. A qualified professional must independently review real decision procedures and evidence. No real taxpayer identifiers, addresses, credentials, account numbers, signatures, personal data, or live private URLs appear anywhere in this fixture. The tax rules, rates, citations, and 2026 statements encoded in the decision procedure have not been reviewed by qualified tax counsel.
Run it
The five-minute steps, expected prompts, and cleanup live in the ACME LangGraph quickstart. After you load the example, that page gives you the case-file download and the command for this deployment and this account.
